    The myth of the 'pristine, untouched Amazon' was always a European trope. Lidar is proving that ancient civilizations were sophisticated ecosystem engineers, shaping the rainforest for centuries without destroying it.

    • pibaker 2 days ago ago

      My understanding of why Europeans think the americas were pristine and barely touched by human existence is because smallpox was ahead of European explorers and by the time Europeans set foot on many places on the continent, they saw ecosystems that had recovered from human intervention after the local population had collapsed.

      • culi 2 days ago ago

        I've heard that explanation as well. But I don't know if "recovered from human intervention" is a fair characterization since they couldn't have been more than a decade behind the smallpox/diseases.

        Estimates range from 5 to 10 million people in the Amazonian Basin by the time Colombus reached the Americas (though some go as high as 20 million).

        I don't think a few years is enough to erase all trace of human intervention. I think it was just so alien a concept to Europeans who kept very tidy woodlands like dehesa in Spain or the coppiced woodlands of Central Europe. As much as 10% of the soil in Amazonia was man-made terrapreta. And they spread what could best be translated as complex polycultural "orchards" of brazilnuts, aqui, coco, and more. Botanists have been puzzled for years by the hyperdominance patterns of some of these trees until anthropologists realized the human connection.

        Anyways I guess what I'm saying is that the Amazonian landscape management is so radically different from what Europeans know that they likely just didn't realize what was before their eyes.

          > they couldn't have been more than a decade behind the smallpox/diseases

          I think it was much more than this. Remember Columbus landed in 1492 and these areas were very connected with trade networks, including from the Carribean islands to the mainlands. Diseases could have spread through most of both of the continents in a decade. And then places like what became the United States were not regularly seeing Europeans until ~1620, so the apocalyptic plague would have already had a 100 year head start. Places like the West Coast and interiors of the US or interior of South America would have been 200 years or more post-plague.

          Also, many of the earliest explorers of the deep interior often described sophisticated and heavily populated societies. But when others eventually reached those areas to find them sparsely populated wilderness those stories were dismissed as just more legends and rumors of cities of gold. See Francisco de Orellana's description of his expedition down the Amazon for a good example of this.

          The weather there is quite brutal. Roads need tons of maintenance to remain passable. This is one of the reasons rivers are such an important transportation network.

          > Amazonian landscape management is so radically different from what Europeans know that they likely just didn't realize what was before their eyes

          This is an interesting explanation. Also, refusing to document previous occupation is a convenient way to claim land rights.

          • indoordin0saur 2 days ago ago

            To add to that, most of their structures in the Amazon would have undoubtedly been built by wood (plentiful) rather than stone (scarce).

            Also, I think 30 years of a field being abandoned in the Amazon is likely more than enough for it to return fully to jungle. It's not like explorers were running around counting tree rings.

            • b_t_s 2 days ago ago

              It's hard for temperate folks to appreciate just how incredibly agressive tropical vegetation growth can be. I'm only subtropical but I've got a tree that's about 6 years old and a foot in diameter. And that's after I've topped it at 5 ft(0 branches left, just a stump) every 6 months or so just to try to keep it under control. If I'd let it run rampant it would be at full growth now, around 50ft and 1.5ft across. I had another tree that went from 10 inch seedling to 10ft and bearing fruit in 9 months. A field abandoned for 30 years in the amazon is 100% jungle.

            • culi 2 days ago ago

              Actually, the vast majority of structures are earthen. Even the article states as much

          Europeans didn't really get to most of the more isolated inland areas in the Americas until the 1600s or well after that, though.

            >Europeans didn't really get to most of the more isolated inland areas in the Americas until the 1600s or well after that, though.

            It takes more than a few decades for things to regrow. There's a reason that half of all towns in New England have the name "field" in them. The impenetrable thicket that characterizes unmaintained New England land would have been foreign to literally every human to ever set foot there prior to the mid 1700s (decades of re-growth after the natives had been mostly driven off but not long enough for complete cultivation by europeans).

            Now, obviously that's not that far inland, but by the time you're talking about the french surveying the continental interior native populations had stabilized. The worst disease epidemics were very much at 1500s and early 1600s thing.

              Have you ever seen a cleared lot that hasn’t been touched for a decade? We have a few near my house, and it is fascinating how wild they have gotten in such a short time.

              Multiplied 10x and set in the rainforest, I would expect signs of humanity to be completely hidden.

              Amazon is different beast, humidity, insect fast growing plants. It is nasure on hyperdrive. I wouldn't be surprised if things took 5-10 times faster than england. Or any more dry european places.

                  Yeah, i spend some time in south america and you can see that even in Rio. If people left the nature would just gulp it up. fun time sleeping in jungle in Iquitos, its crazy how dens the jungle can be

            • ywvcbk a day ago ago

              The population collapse in New England happened only a couple of years before the Plymouth colony was established though (they didn't have any meaningful contact with the Spanish colonies where it happened in the mid and early 1500s).

              Of course probably it took quite a bit more for it to reach the Amazon but it's not like Europeans were that familiar or explore the region that much until the 1800s or so.

            • walthamstow 2 days ago ago

              Is -field really that common? I live in old England and many towns here are called -field, although granted not as many as -ton/-don.

              • cucumber3732842 2 days ago ago

                Not as common as old England but vastly more common than the rest of the country because the charters had to be petitioned for and approved by several layers of intolerable assholes so unoffensive descriptive names like <thing>field were preferred over just about everything else. See also North/South/East/West<thing that was previously approved>. Kind of like how modern corporate safe culture bland-washes everything.

                They mostly gave all the waterways colloquial names based on the Indians and of course that got copy-pasta'd onto all sorts of charts and maps so the government couldn't redefine those even if they wanted to.

                Most of the rest of the country (including the mid Atlantic despite being settled at the same time) was far more deliberately surveyed and named.

          There wasn't a single civilization there. The same way if you arrived in Greece during the roman period you'd have 2000 year old temples to look at and if you go there now you have both the 4000 year old ones and the 2000 year old ones. In the amazon some of the stuff that is there was ancient already at the time of the Discoveries.

          • culi 2 days ago ago

            > There wasn't a single civilization there.

            That's what I said. There have been multiple. The linked article is about the Aquiry civilization which numbered 3 million people in only 3% of the land. The Marajoara outlasted them. The Upano Valley civilization predates both of them by 100 years and built dense garden cities. The Beni Mounds spanned over 20k earthen mounds and human-made forest islands that were connected by massive canals and causeways

          > The World Without Us is a 2007 non-fiction book about what would happen to the natural and built environment if humans suddenly disappeared... it outlines, for example, how cities and houses would deteriorate, how long man-made artifacts would last, and how remaining lifeforms would evolve. Weisman concludes that residential neighborhoods would become forests within 500 years

        • ErigmolCt 2 days ago ago

          A landscape does not become "pristine" a decade after millions of people disappear. The human influence would still be everywhere, but it would not necessarily look like European agriculture

        Europeans often failed to recognize Indigenous land management because it did not resemble European cities or farms

        • jeltz 2 days ago ago

          No, what they failed to recognize was indigenous land management that had been abandoned for many decades. In remote areas smallpox moved quite far ahead of European settlers.

        • suddenlybananas 2 days ago ago

          There's accounts of Europeans encountering cities in the Amazon, people didn't take them seriously since they disappeared in the intervening time.

    • netbioserror 2 days ago ago

      That is definitely not what the Maya did. Or really any civilization with large permanent cities. The record of forest cutting once settlements reach a certain size is consistent and global. The Amazon simply experienced a full civilizational collapse and more than enough time untouched to recover.

      It might suffice to say: The myth of sophisticated indigenous ecosystem engineers who harmonize with nature is a European trope.

      Whenever any culture larger and more settled than hunter-gatherers has traditions of forest management and ecosystem balance, don't immediately attribute to them magical wisdom that Europeans somehow lack. Consider that those traditions are an ancient memory of one or more catastrophic ecosystem collapses and the practices of the people who survived them.

      • culi 2 days ago ago

        I mean throughout the Americas you see really complex polycultural farming traditions including the famous chinampas. In Mesoamerica you also have the milpa cycle which is a system where you clear most herbs and lightly burn it to grow your crops in polycultures. After a few years, you grow more trees and these fields turn more into managed orchards that include both fruit trees and trees grown for lumbar. Eventually you let it progress into a closed canopy system.

        That's just one example, but there are plenty other I could think of that are in very stark contrast to anything you see from European civilizations.

        • somenameforme 2 days ago ago

          With these things it's always an issue of scale. What people don't realize about e.g. homesteading is that it's actually really easy to be entirely self sufficient on very small plots of land. But the tricky thing in the past was transport - when you start shoving many thousands of people into very small areas, you need to start producing more and more food in (relatively) smaller and smaller areas.

          Modern times has alleviated this constraint because of mass transport. Now moving tons of cargo hundreds of miles, or even half way around the world, is trivial and relatively rapid, but in ancient times you're looking at moving small amounts of cargo extremely slowly, all under the time pressure of spoilage/infestation. The way places like Rome solved this, or at least alleviated it, was by using river transport but then you're imposing some significant technological, infrastructural, and geographical requirements on settlements.

          And then you also need to deal with bad harvests, war, and other such issues. In decentralized systems where most are doing their own thing, this isn't such a big deal. But in a heavily centralized system where potentially millions of people are dependent upon deliveries, a single disrupted harvest could spell the end of a civilization if not properly prepared for. And ancient beliefs that things like human sacrifice could ensure rain were likely in opposition to the rational necessity for preparation of inevitable failures.

          ---

          As a related topic, this is also why war is considered a game of logistics. Think about feeding and providing the other necessities for 10,000 people for just one day. Now imagine doing this for weeks, months, and years - when all those necessities need to come through areas that are potentially being attacked. The fact that war with armies of hundreds of thousands is even possible is quite amazing when you think about the logistics involved just to survive, let alone actually engage in combat.

            This is one of the reasons they flourished near river networks that provided easier transport as well as food. They also build canals, but I’m not sure they were for navigation as much as irrigation.

          Interesting. Do you know of anything somewhat similar for Africa, ignoring the lands of Egypt and the lands near the Mediterranean Sea?

          • t-3 2 days ago ago

            If you hadn't excluded them, Morocco has a 2000 year old managed food forest.

          • culi 2 days ago ago

            I recall reading of somewhat similar rotational cropping traditions indigenous to Africa though those centered mostly around root crops like yams. Modern smallholder farms still often practice rotational cropping because of this history (something which the west has only relatively recently come around on).

            East Africa practiced stuff like homegardens which can be complex, multi-layered agroforestry systems that usually surround homesteads. I've heard the Hausa traditionally did something similar.

            I haven't read nearly as much on African agroforestry systems though so I can't recommend much readings. Most of what I recall comes from a college course I took a very long time ago on economic anthropology

              I am not quite sure what you mean by this. Is it consistent with this?

              > From the 9th century to the 11th century, farmers in Europe transitioned from a two-field system to a three-field system.

              > Ancient Near Eastern farmers practiced crop rotation in 6000 BC, alternately planting legumes and cereals.[1][2][better source needed]

              > In China both the two- and three-field systems had been used since the Eastern Zhou period.[3]

              And shouldn't the "West" be capitalized in this context, since it is used as a name?

              Homegardens seem much smaller in scale than large-scale chinampas as practiced by the Aztecs, right?

              • culi 2 days ago ago

                They are larger than you'd think. A couple acres. But chinampas are definitely in another league

    • ErigmolCt 2 days ago ago

      The important lesson is not that ancient people left no ecological footprint, but that a heavily managed landscape can still remain remarkably biodiverse

        The lesson is more that indigenous people were (+ are) part of the ecology, not separate from it or above it. With cultural, social, technological, and spiritual practices that were formed dialectically and hyper-locally with the ecology, as a result of it, and as part of it. Often considered a keystone species in these ecologies.

        • modo_mario 2 days ago ago

          Indigenous people in north america contributed to multiple extinctions.

          This is the noble savage trope you're putting on display

          • cucumber3732842 2 days ago ago

            This has nothing to do with "noble savage" or whatever other ideologically loaded words you want to surgically introduce to manipulate people's opinions.

            Humans are the apex predator. They have a huge influence on whatever the downstream ecological equilibrium winds up being.

            This is hardest to deny in formerly glaciated regions because humans were there exerting pressure on the ecosystem the day after the glacier left (well not quite, but close enough). So if you take for example somewhere like pre-colombian Wisconsin, the development eventually pine forest and then hardwood forest all that happened with humans around eating things. The number of wolves you get depends on the number of deer you have which depends on how many the humans eat. And of course the deer eat things too so they affect the plant balance, which affects the other wildlife. And so on and so on. It's a complex web.

            In places like the Amazon it's less cut and clear because humans showed up around/just before the last serious change in climate (end of ice age) but once again they've been there for the entire development of the "modern" ecosystem so whatever your balance of plants and animals is that balance is reflective of the pressures put on it by human activity.

            • modo_mario 2 days ago ago

              Nah, I was adressing the idiology already present there.

              I don't dispute that humans are in essence a keystone species, part of nature, etc, etc but the OP talked about indiginous people specifically. We can just as easily say that the japanese were ecologically compatible....up to a point.

              The only reason it's brought up is due the idea of the indiginous in tune with nature who was essentially not limited in his ability to further exploit but chooses not to.

              • GroksBarnacles 2 days ago ago

                Shouldn't you consider individual populations, cultures separately, and not be lumping all native people's together? One can do something another didn't.

          • tkel 2 days ago ago

            With regards to the Late Pleistocene extinction overkill hypothesis that you are referring to, your information is out of date, more recent evidence suggests that humans played only a minor or incidental role, with climate change (the end of an ice age), and habitat restructuring being the primary drivers.

            I don't think you understand what the noble savage trope is. I'm commenting on the development of indigenous human societies in the Americas. The vast majority of them were ecologically compatible. This is not a commentary on the morality of individuals. To take the Mexica empire as an example, they were not a moral civilization by our standards (neither were the Spanish colonizers), and they had an over-reliance on corn and obsidian, but other than that they survived in a way that did not stress or extinguish or destabilize the surrounding ecology.

            • curioadu 2 days ago ago

              I do not quite buy your arguments, and I am skeptical of several claims that you make. Without specific sources, it is more difficult for me to contest them, though I will not request sources.

              From your perspective, what caused the extinction of several megafauna/large species of animals after the arrival of Aboriginals in Australia?

              • frmersdog 2 days ago ago

                That's mistaking correlation for causation. I don't have proof, but let's consider an alternative: that the climate change that made those areas newly-hospitable to humans made them inhospitable to megafauna. Can you falsify "all of the species were subject to the same environmental shift" before you jump to "arriving humans hunted them all to extinction"?

                (And I recognize the parallels to some unsavory arguments, and would like to point out that the evidence regarding contemporary man-made climate change is strong and sound. But that's with industrialization and a couple orders of magnitude more people on the planet.)

                • graemep a day ago ago

                  I think if you consider that single instance it is mistaking correlation for causation.

                  However, it happens every time, with a lag. In different climates and environments. When humans expanded out of Africa, spread out over Eurasia, reached North America, South America, Australia, new Zealand extinction of megafauna always followed.

                  We know that there was large scale hunting and humans are highly effective hunters. Hunting megafauna is the easiest available food source for a pre-industrial society until they get to the point where there is too little megafauna left (and changes, eventually including farming follow). Unlike large carnivores we are not dependent on hunting megafauna so our human numbers do not drop when they are in short supply.

                  • frmersdog 17 hours ago ago

                    It's still mistaking correlation for causation, even when considering multiple instances, if you can't describe an unfalsifiable mechanic as the cause.

                    There are two problems here:

                    1) It hasn't actually happened every time. Elephants, hippopotamuses, large whales, polar bears, grizzly brown bears, certain large bovines, and moose still exist.

                    2) Extinctions of megafauna are distributed across a time delta from human arrival. I don't know for sure, but I would wager that that delta doesn't necessarily correlate with date (as a proxy for technological development).

                    That is to say, "humans arrive -> everything big dies" is not so cut-and-dry a rule. It should be clear that other factors are involved.

                    I'll suggest a third option: humans hunt megafauna to extinction in the presence of conditions that favor such behavior - perhaps climatic, geographic, and/or cultural. So, it happens. But it doesn't always happen.

                    For the purposes of this conversation, I don't think you've proven the original contention wrong, which was that indigenous people in the Americas found a niche which made their presence and behavior sustainable over long periods of time. If your evidence is the total extinction of American megafauna, then you would be forced to admit that you were incorrect. In fact, you potentially argue for the opposite: in clearing some megafauna but sparing others, humans did indeed carve out a potentially sustainable ecological niche, which their continued presence helps to prove was sustainable. At least, until culturally disparate humans arrived.

                    • graemep 16 hours ago ago

                      A significant number of mega fauna species is hunted to extinction whenever humans arrive.

                      > If your evidence is the total extinction of American megafauna

                      The evidence is the extinction of most American megafauna species.

                      > In fact, you potentially argue for the opposite: in clearing some megafauna but sparing others, humans did indeed carve out a potentially sustainable ecological niche, which their continued presence helps to prove was sustainable.

                      Humans have continued to survive everywhere, so that is evidence the the presence of humans everywhere has been sustainable.

                      The comment making the claim about indigenous societies in the Americas is that they are "ecologically compatible". They are compatible with an ecology they altered. This is, again, true everywhere. You might argue that industrialisation has changed this as a (relatively) stable state is not reached because of continuing rapid change, but it was true before industrialisation.

                      > I'll suggest a third option: humans hunt megafauna to extinction in the presence of conditions that favor such behavior - perhaps climatic, geographic, and/or cultural. So, it happens. But it doesn't always happen.

                      I have two objections to that:

                      1. Its not all megafauna, it is most. Some species can survive humans. 2. The extinctions have happened across many different climates and cultures and on every continent and many islands.

                      It is not proved beyond doubt that humans have always caused extinctions, but the pattern is very consistent, which makes it by far the most likely explanation. Even where hunting is not the direct cause, many things humans do (such as agriculture) will destroy their habitats.

                      Where humans did not arrive until much later than most places (e.g. in places such as New Zealand or Madagascar) megafauna survived until after they did, and were then gone with a few hundred or a few thousand years.

Though, I was not aware of there being competing theories regarding the significant number of extinct megafauna species around the gross time interval of the arrival of Aboriginals to Australia and Tasmania, my apologies. There are two competing set of theories, namely human-caused ones and natural-climate-caused ones, as far as I can tell. I was only aware of or could only remember the first type of theory.

                  For a clearer and possibly more settled and agreed upon example: From your or the other commenter's perspective, what caused the extinction of Moa after the arrival of Maori in New Zealand? Some claims that the Moa went extinct within 100 years of human settlement, and that it had a large population before that

                    >The extinction of all moa species occurred relatively swiftly, between 1380 and 1440, making it one of the most rapid extinctions in history. Contributing factors included habitat destruction through woodland burning, the introduction of non-native predators such as dogs and rats, and the birds' natural life cycle, which featured low egg production.

                    It's not a good example to use to prove your contention, because it's an outlier, and because it involved the use of technology that wasn't necessarily available to other incidences of megafauna extinction.

              What does ecologically compatible mean to you? Because it is expressed as some kind of choice.

              Were the japanese naturally compatible in the distant past? And if in the end this ecological compatibility just so strongly correlated with development and ability than what boundary does it actually refer to?

              • randomImmigrant 2 days ago ago

                Relax. I don’t think the OP means there’s some genetic flaw in Europeans that makes them ecologically imbalanced by nature.

                They’re saying that a lot of indigenous culture and practice was more sustainable. This may be for various reasons, and isn’t true only of American indigenous people but almost certainly people in Japan, India, Australia, etc., where urban civilization that depended on large scale agriculture didn’t take hold.

                This is, if you see it, only evidence that there’s no inevitable path for progress and development for our species. We have the ability to look back, see how different parts of the world handled their engagement with their environment, when and where that degraded, and make changes, proving that none of this is inherent to any part of our species, but rather cultural and social structures that emerged for a bundle of reasons.

                  > They’re saying that a lot of indigenous culture and practice was more sustainable

                  Europe seems very sustainable to me, people have been living there for thousands of years and are still thriving. Why do you say Europeans doesn't have sustainable agriculture? They wouldn't have been able to become so dominant otherwise.

                  • randomImmigrant 13 hours ago ago

                    Because “Europe” hasn’t been one thing for any length of time.

                    And what even does “become so dominant” mean? You do know evolution isn’t some straight accumulative equation, right? Dominance means all things done are good?

                    Dominance over what time scale? Sustainable over what timescale?

                    The sad fact is, for any society, short term dominance causes long term instability. That multiplies a lot when you spend hundreds of years accumulating land and control and wealth. It’s sure sweet while the going lasts. Then what happens when there’s pushback?

                    We can’t fully answer that question yet. We’re living through that post colonial era of Europe.

                    My hope is Europe thrives. I doubt it will if it goes back to its old extractive practices. Thankfully, most governments in Europe seem to have moved past that mentality.

        • suddenlybananas 2 days ago ago

          Indigenous people aren't any more or less of the ecology than anyone else, unless you believe in blood and soil. Humans are part of the ecology, being indigenous has nothing to do with it.

          • curioadu 2 days ago ago

            In some ways I agree with you, but I also think that the other commenter indirectly might uncover some insights. For instance, Australian Aboriginals mighy have historically both; fire-stick farmed ("farming" in the sense of clearing land for animals to hunt, apart from some foraging, as far as I can tell) so much and in such a large area that both large animal species and perhaps some plant species went extinct or were greatly decreased in numbers and area; and done it for so many years and generations that the ecology changed and adapted according to repeated and frequent fire-stick farming, to the point of becoming reliant on humans doing fire-stick farming.

            • suddenlybananas 2 days ago ago

              Of course, but that's no different than the changes brought on by urbanization or climate change due to carbon emissions.

              • tkel 2 days ago ago

                Seems as though you are intentionally misunderstanding me. Urbanization is a practice that humans developed without ecological integration, it is a practice of subjugating or disregarding the surrounding ecology, and extermination of most of life within an ecosystem. As opposed to living within an ecosystem for thousands of years, not above or apart from it, most indigenous human societies in the Americas developed in such a way that is compatible and unique to it's hyperlocal ecological niche.

                Do you rely on the surrounding plants and animals in your area for sustenance, creating tools, daily life, etc? You do not, that's what I mean by living above/apart. Living in this way does not lead to an ecological society or a shared knowledge base of the surrounding ecology. Do your spiritual and cultural practices involve or integrate that reliance in some way? That's what I'm getting at.

            Not true, there are obviously other ways. There is an intuitive distinction between living in harmony with natural systems and simply dominating them with technology. That is all you have to believe, it doesn't have to be grounded in ethnonationalism.

            Humans are unquestionably part of the environment, and everything humans do bends the environment to their will, but it would clearly be at odds with how we use words to argue that say a nuclear power station is just as much "part of the ecology" as cultivation of soil.

            • RugnirViking 2 days ago ago

              > distinction between natural systems and simply dominating them with technology

              No? There's a rhetorical distinction, there isn't a physical distinction. It's like holistic medicine vs modern medicine, or wellness vs health, or human-centered design vs regular design, or chemical-free food vs regular food

              Any given thing is one or the other of these soley based on your perspective of it. Im sending this message to you right now by performing a ritual on a object made of rocks some guy found in the ground

              • tempfile 2 days ago ago

                Of course there isn't a physical distinction. This is a bit like saying there isn't a difference between a novel and a poem, because they're just words on a page. The distinction is nonphysical, but it is also obviously not rhetorical either. I said "intuitive" distinction, I'm not sure why you didn't criticise that directly since it admits that the distinction is not completely precise.

                What exactly are you doubting? Is the word "harmony" meaningless gibberish in your opinion? Are there any nonphysical words you admit are meaningful?

              • tkel 2 days ago ago

                Everything is nature , but clearly human society is also distinct. Both can be true. Some anthropologist philosophers have referred to this as "first nature" and "second nature", second nature being human society which is also part of first nature but distinct from it.

                • suddenlybananas 2 days ago ago

                  But you're making out that indigenous people are part of this "first nature" rather than the "second nature", while industrial civilisation is strictly "second nature" which is frankly racist.

                  • tkel 2 days ago ago

                    The 201 definition is that second nature is a realm of development beyond the bio-social realm, that tends to form into institutions that have their own methods and rate of development and change beyond biological evolution (natural selection, gene flow, mutual aid, etc). Bands, clans, tribes, federations, nations, etc.

                    Other animals such as orcas also have been shown to have societies, language, culture, and history that is passed onto children. You could perhaps say that is also second nature.

                    Call it what you want, but clearly modern human society is distinct in that it stands above (quite literally in the form of cities) and uniquely has the ability to threaten the rest of life on the planet. While at the same time being part of nature.

                    Humans are part of the surrounding ecology whether we recognize it or not, as others have noted in this thread. The difference is many indigenous societies have tended to recognize it and integrate it into socio-cultural practices as a necessary part of survival in their local ecology, while our modern human society mostly does not.

                    Consider the Kucadikadi people of now-Mono Lake , whose autonym literally means "eaters of the brine fly pupae". That is how closely their society, culture, and language is related to their local ecology, which "evolved" (in the 2nd nature sense) out of thousands of years of human society development and survival in that place. Notably their society has not developed to threaten or extinquish the brine flies on which they depend.

        • edbaskerville 2 days ago ago

          Unsurprisingly this one generated a lot of responses.

          My working hypothesis for this question involves colonization, technologically driven scales of time and space, and selection. The essence is totally obvious: either you develop sustainable practices or you go extinct.

          Consider a group of people colonizing an area previously uninhabited by humans. When they arrive, they will disrupt the local ecosystem to some extent.

          In some cases, the new combined system of ecosystem structure and human culture will settle into an attractor that can support humans for a long time (relative to frequency of colonization). In other cases, it will not, and the human population will die out. (Externally driven parameter changes can also turn a sustainable system into an unsustainable one.)

          With a low enough colonization rate, most active communities will be operating sustainably.

          Over time, technology increases the rate of spread of humanity. Cultures with more advanced technology increasingly spread into existing settlements as well as taking over existing land.

          But the basic process continues: some systems last; some do not. The ones that last longer are the ones with sustainable practices.

          This process is now operating at a global scale. Either we get sustainable, or things get bad.

          Some people have concluded that the easier path is to colonize other planets.

      The headline literally says they lived in 3% of the forest area, which implies that the vast majority of the rest of the forest actually was untouched

        Perhaps, but was it untouched by design, or was it untouched because it wasn't economically feasible for them to exploit it?

        Those two are very very different when it comes to assigning virtuous environmental brownie-points, and the latter is the default across most civilizations ever known.

            > Since when is "assigning virtuous environmental brownie-points" the topic of discussion?

            I think it's very straightforward. Here's a recap of the thread, you can see it in the quote for the first item:

            1. khanhnguyen8386 implied that they were "sophisticated ecosystem engineers, shaping the rainforest for centuries without destroying it."

            2. smt88 challenged that by pointing that 97% of "the rainforest" was probably untouched by this group, as opposed to shaped deliberately.

            3. I (Terr_) chime in to emphasize that we shouldn't assume a region was intentionally left-alone when the much simpler explanation is that it wasn't practical to exploit it.

            > Your original claim which GP responded to is unrelated to that.

            You have also confused me with some other user.

            • boomlinde 2 days ago ago

              Yeah, I confused you for another user.

              Still, I don't get where "virtuous environmental brownie-points" enter the discussion or how the first reply pertains to them. It seems like a simple factual statement that is either true or false and can be evaluated as such without invoking virtuous brownie points.

              That the Amazon remained largely untouched is true regardless of whether that was the result of a deliberate effort, a technological limitation, a lack of need or any other reason. No one uses "preserved" until now. It can simultaneously be true that the populated areas of the Amazon where deliberately and carefully managed by the population and that the Amazon was largely untouched for any other reason.

                > It can simultaneously be true that the populated areas of the Amazon where deliberately and carefully managed by the population and that the Amazon was largely untouched for any other reason.

                Certainly, though nothing about the quoted fact that 97% of forest was uninhabited should lead us to make statements like "the pristine untouched Amazon idea is a European myth", nor does it give any information to go off of regarding their possible knowledge of environmental engineering.

                • boomlinde 2 days ago ago

                  Perhaps they weren't basing their statement on the "quoted fact" which was later posted in response to their statement (which FWIW isn't factual; as someone else points out this was not the only Amazonian civilization).

    • gabriel666smith 2 days ago ago

      Whilst being aware that the civilization in question ended significantly before European arrival in South America, I have two questions that hopefully someone smart here can help with:

      1. The spread of disease (smallpox specifically) being fast enough that most European sources describe a relatively uninhabited Amazon strikes me as potentially interesting. This means that contact and trade was happening between locales. We know that part is true from many sources, but:

      A) Can we roughly model the spread of smallpox by looking for (for example) populated areas mentioned in one European source that are unmentioned, or mentioned as empty, by another source that would have likely crossed paths with that civ?

      B) Can this tell us anything about trade routes and volume? Can we make any inferences about pop density, even very weak inferences, which might help us know where to look for stronger evidence? It does seem like each European discovery historically revises the estimated population(s) upwards.

      2. LiDAR is awesome. Maybe not in the Amazon - in less foliage-dense places - is it being combined with, for example, an EMF (or some other kind of more granular lightweight detection system) - strapped to a drone?

      It feels like once we see something interesting on LiDAR, sending a swarm of lightweight drones with some kind of metal detector sellotaped to the underside is quite a quick way to get interesting information. I don’t know a lot about radio waves, so I don’t know if there’s a suitably lightweight detector for this purpose.

          I wonder if you couldn’t distribute heavier parts across a swarm - perhaps separating the sender and receiver(s) - running the wave at an angle (or many angles simultaneously) to the surface.

          The sources mention mostly aircraft, rather than drones, and human pilots aren’t as good as drones at flying in extremely tight formations, which might allow (if the tech allows in the first place!) parts to be distributed to work around pesky laws of flight.

          • curioadu 2 days ago ago

            Is that vaguely related to slash-and-burn?

            Did it also change the ecological system of Australia? Some articles said that Aboriginals might have caused the extinction of a lot of larger animals in different ways, arguably superficially similar to how the mammuth was made extinct and how lions were hunted to extinction in Europe. https://en.wikipedia.org/wiki/Fire-stick_farming#History . Was the plant diversity changed or lowered by the Aboriginals over the years?

            Is there a difference in the approaches between "fire-stick burning", and the advanced farming or agricultural practices of for instance the Aztecs? Did Aboriginals and some of the Amerindian peoples north of the Aztecs do "fire-stick farming" by simply burning a region and then move in and simply primarily hunt and also gather from certain plants a bit, slightly organized; or did they have large-scale, high-density farming of crops like the Aztecs? Would Pueblos' farming techniques, and those doing Three Sisters farming techniques, be closer to that of the Aztecs than to fire-stick burning? Was fire-stick burning typically more nomadic, and the Aztecs' and others' techniques more sedentary?

            Shrimple as. The scheme worked for millennia with zero problems. Nobody had a problem with beef production until tariffs and other fuckery was invented.

              Beef should not the the main meat in some places. There is a particular problem in the Americas with cattle. Tariffs do sometimes reduce imports from places where cattle are not a great fit - i.e. the very places where forests are cleared too grow grass.

              All the beef (and most other meat too) I eat is grown in the same country. For a premium you can get higher quality local (i.e. same county) meat.

      shaping the rainforest for centuries without destroying it.

      That's the myth. A lot of native populations farmed. Where do you think that farmland came from? It came from tearing down forests and tearing down trees. And yes, ancient peoples could do that with fire, and with older axes.

      And not only was that wood cut down, but it was also used for fuel. Fuel for fires, for cooking. Fuel to warm a house at night.

      Mines were a thing. Copper and lead and other metals were dug up from mines Surface mines were heavily damaging to the environment, with all sorts of minerals being dug up, and washed into the local water and river.

      In fact, the only difference between older civilizations, and our civilization is that we have the technological capability to cause more damage. Native North and South Americans, were not any better, about the environment or living at peace and harmony with nature.

      As an aside the same goes for violence, for war. Endless North American and South American civilizations waged war. They enslaved, they enslaved other civilizations, they warred with one another, they fought constantly, and just as today those nations had peaceful entities and warlike aggressive entities. Nothing has changed, nothing is different between the historical colonialistic civilizations of the West, and the new world.

      The Aztecs were supremely violent, taking over civilizations all over the place, just as colonial as the West was.

      You may wonder why I'm waxing and waning deeply on this topic, but the reason is that there seems to be this predominant thought that somehow, North American civilizations were perfect and pristine, and lived in utter utopian peace with nature and, each other. Nothing could be further from the truth.

      And do you know why? Because they were human beings.

      None of this says that the colonial behavior was perfect when European nations came here. Many things were done that should not have been done.

      However, if you look at the history of the human race, including modern times, colonial behavior has always, I repeat, always been the case. Whether you were the Persian Empire, whether you were what is now India/Pakistan, whether you were China, whether you were any nation on the planet, there has been a history of colonial behavior. This includes all North American and South American peoples.

      China was a wide-ranging number of kingdoms, that eventually settled to the Five Kingdoms and then a unified country. This was colonialism. This was subjugation and conquering of other peoples, until a unified country existed.

      You can look at the Roman Empire, the Grecian Empire, the Babylonians. You can go and look at any culture, any history. You can look at modern times, and you can see what might be deemed colonialistic behavior.

      I cite all of this, because there seems to be recent thought in the last 20 years that somehow, Native Americans and South Americans lived in utter peace and harmony with their environment and each other. Nothing could be further from the truth.

      So back to the original point that kicked off this rantish blather, no ancient civilizations did not live in harmony with the environment on purpose, and any that had the technological capability or the framework of a civilization like the Aztecs, raised their local environment, ripped down forests, had open mines, destroyed the local environment, hands down.

      • graemep 2 days ago ago

        The myth of indigenous people's living in harmony with nature is just the current version of the myth of the "noble savage" and remains a disguise for racism, as it takes away the history and moral agency of such people, and trivialises their culture to a "natural state".

        The fact is that human being usually alter their environment drastically. They might eventually reach a stable state, but after changing. All over the world megafauna disappeared just as human being appeared.

        I see you are very uninformed about the original caretakers of the Australian continent .. who very definitely cultivated the land so that there was an abundance of food safety for all. They were a lot more altruistic, also, about how they prepared food - leaving things in place for any forthcoming caretakers that would enter the region.

        • Jensson 2 days ago ago

          Every population grow to where they barely can support themselves, including Australian natives. It doesn't matter what you do, until we got good contraceptives starvation was a fact in every culture except after periods where food productivity quickly increased or population levels quickly decreased.

          The only way to not starve is to not have sex, and no culture managed that well.

      I've always been confused by the idea that we know all civilisation that has happened on earth, human or otherwise. Written record doesn't go back very far at all, and even archeological evidence is lacking.

      Its believed that homo sapiens have been around for at least 300,000 years and yet we think almost all of that was entirely without civilization.

      We find fossil records of dinosaurs but we have little to no evidence of what would have been before them, presumably there was an extinction event prior to them as well.

      It seems foolish to think we are the latest incarnation of the only chain of civilization that had ever happened on Earth.

        Depends what you call civilization. If there was a civilization what happened to it and why did it leave no trace.

        > We find fossil records of dinosaurs but we have little to no evidence of what would have been before them, presumably there was an extinction event prior to them as well.

        Actually we do have evidence of what came before them, and there were extinction events.

        > It seems foolish to think we are the latest incarnation of the only chain of civilization that had ever happened on Earth.

        We might not know about previous civilizations (that is the point of the Silurian Hypothesis - a lot of traces will disappear over time) but we have no evidence that there was any previous civilization, or of any sufficiently intelligent animal to build one. The oldest stone tools we have found are only about 3m years old.

        You would like the book "Dawn of Everything" by David Graeber.

        It does a lot to talk about modern anthropological studies that corrected a lot of misconceptions about early humans. Really fascinating book, basically postulates that humans have always been imaginative social creatures that were routinely well travelled; and the idea that early humans weren't also politically or culturally advance is wrong. In fact some societies were purposely designed to ensure things like hierarchy wouldn't exist for example; these societies persisted for thousands of years.

        Really interesting book.

        • culi 2 days ago ago

          Yes exactly. The myths of native people being hyperegalitarian, one-with-nature types started because colonists came upon cultures in the North East woodlands. Those same people, just a few decades before that were living in Cahokia which was at one point larger than any city in Europe. It was a massive urban city that was also very hierarchical. The hyperegalitarian Algonquian and Haudenosaunee/Iroquois people were basically the result of a successful political revolution that decided to organize themselves like that in response to the hierarchies they experienced.

            While many Amerindians had impressive achievements considering their almost complete isolation from the rest of the world, your claim seems misleading.

            > At its apex around 1100 AD, the city [Cahokia] covered about 6 square miles (16 km2), included about 120 earthworks in a wide range of sizes, shapes, and functions, and had a population of between 15,000 and 20,000 people.[5][a]

            > During the 1st and 2nd centuries CE, the population of the city of Rome is conventionally estimated at one million inhabitants.

            And there are much better examples according to some sources of large cities in the Americas than Cahokia.

            > Hernan Cortés arrived in Tenochtitlan on 8 November 1519. Although there are no precise numbers, the city's population has been estimated at between 200,000 and 400,000 inhabitants,[27] placing Tenochtitlan among the largest cities in the world at that time.[28] Compared to the cities of Europe, only Paris, Venice and Constantinople might have rivaled it.

            > In the 9th and 10th centuries, Constantinople had a population of between 500,000 and 800,000.[60]

            > With the restoration of firm central government, the empire became fabulously wealthy. The population was rising (estimates for Constantinople in the 12th century vary from some 100,000 to 500,000), and towns and cities across the realm flourished.

            > Kaifeng-Dongjing became largest and most prosperous city in China, with a population of over 400,000 living both inside and outside the city wall. The historian Jacques Gernet provides a lively picture of life in this period in his Daily Life in China on the Eve of the Mongol Invasion, 1250-1276, which often draws on Dongjing Meng Hua Lu, a nostalgic memoir of the city.[14]

            > Around 750 AD, Chang'an was called a "million-man city" in Chinese records; most modern estimates put the population within the walls of the Tang city at around 800,000–1,000,000.[1]

            The Iroquois had slaves, they weren't hyperegalitarian.

            • I-M-S 2 days ago ago

              The Iroquois did not have slaves. You might be thinking of individuals that were sometimes taken as compensation for people killed in battle. However, these people were then fully assimilated into the society with all the rights and obligations of anyone in the clan (in most cases, they would even take the name of the deceased). To call these people "slaves" is much more revealing of the Western civilization than that of First Nations.

              • suddenlybananas 2 days ago ago

                Did those people have the right to leave or do what they wanted?

                >To modern Westerners, the use of such a kinship metaphor suggests and is believed to reflect genuine nurturing and closeness; however, in Africa and elsewhere it conveys an entirely different meaning: authority and subordination.

                >Villagers, forming a gauntlet and armed with clubs, fire-brands, sticks, and other weapons, greeted the prisoners and rained down on these hapless individuals blows designed to inflict pain but not to kill This was often followed by torture and public humiliation and then deliverance to the grieving families, whose "matrons then chose either to adopt or to execute them," or both

                If you look at pages 11-13, there's a discussion of ritual torture to prevent captives from escaping. 13-14 deal with the torture and execution of unruly captives. 15-16 deal with the etymological relationship between "slave" and "pet/livestock" in Iroquonian languages like Mohawk. Pages 17 and 18 discuss people preferring suicide to capture and the sexual exploitation of female captives.

In some cases, captives were only adopted after a period of slavery. For example, the Iroquoian peoples (not just the Iroquois tribes) often adopted captives, but for religious reasons there was a process, procedures, and many seasons when such adoptions were delayed until the proper spiritual times.

                    >In the cultural practices of the Iroquoian peoples, also rooted in a matrilineal system with men and women having equal value, any child would have the status determined by the woman's clan. More typically, tribes took women and children captives for adoption, as they tended to adapt more easily into new ways.

        Our earliest record is the Rigveda (a written down oral tradition, we don't know exactly how far back it goes).

        I suggest you try to read it at least once. It's almost incomprehensible.

        • rishav_sharan 2 days ago ago

          No. And it's not even close.

          Rigveda would be around 1500Bce. Even Sumerian cuneiform would be far older at 3000 bce. If you want oldest oral records, some Australian aboriginal stories would be the ones at 8000 bce

          • gaigalas 2 days ago ago

            The Rigveda is the the earliest unbroken kept record.

            The Sumerian tablets are likely older, but they were forgotten and then re-deciphered. The transliterations still carry educated choices made by a scholar (there's only so much you can do when the record breaks for a long time).

            Meanwhile, we know exactly how people spoke those early vedas because there is a tradition that keeps chanting it, without stopping, since before it was written down. That chanting has error correction mechanisms, redundancy and other impressive features that further place the Rigveda in a unique place among earlier works.

            • rishav_sharan 2 days ago ago

              Can you share some thing to read up on this. Most of these claims do sound fantastical. I am not even sure how would one verify that Rigveda is an "unbroken" oral recitation over thousands of years.

              • gaigalas 2 days ago ago

                This is a well-known, established scholarly fact.

                https://en.wikipedia.org/wiki/Padapatha

                > The oral tradition of the Vedas (Śruti) consists of several pathas, "recitations" or ways of chanting the Vedic mantras. Such traditions of Vedic chant are often considered the oldest unbroken oral tradition in existence, the fixation of the Vedic texts (samhitas) as preserved dating to roughly the time of Homer (early Iron Age or 800 BC).

                https://ich.unesco.org/en/RL/tradition-of-vedic-chanting-000...

                > The value of this tradition lies not only in the rich content of its oral literature but also in the ingenious techniques employed by the Brahmin priests in preserving the texts intact over thousands of years. To ensure that the sound of each word remains unaltered, practitioners are taught from childhood complex recitation techniques that are based on tonal accents, a unique manner of pronouncing each letter and specific speech combinations.

        So what do you claim as 'not foolish' to think?

        That there were non-human civilizations before the dinosaurs?

        Do you consider ants/bees to have civilizations or is it just humans currently?

        Or do you mean that there were human civilizations in the prehistory? And what do you mean by that – is it foolish to think that they were hunter gatherers for hundreds of years?

        I don't mean to make strawmans, that's why I'm asking.

        • _heimdall 2 days ago ago

          Well for starters I'd say my basic point is that its foolish to assume nothing came before what we do know about. There could have been past human civilizations, with enough time any natural building materials would effectively vanish. More interesting to me, though, would be non-human civilizations that could have existed well before humans ever came around.

          I don't consider animals to have civilizations simply for having complex groups (ants or bees, for example). Though separately they do absolutely have emotions, family bonds, and long memories. My cows have proven that, each one is a different personality with their own clicks among the herd, and each cow treats the me and my wife differently so its not like "this one's always mean, this one wants to be petted" etc.

    There’s an incredible story about Orellana, who captained the first journey down the Amazon River in the 1500’s with Gaspar de Carvajal taking notes. They described cities of hundreds of thousands of people, and sailing for days going through city after city.

    Decades later people tried to repeat the journey and didn’t find major cities, ultimately calling Carvajal a liar. The reality was everyone died due to new diseases. It’s hard to imagine the impact disease had on South America in particular

    • tastyfreeze 2 days ago ago

      North America as well. Estimates are that 80-95% of the native population on the continent in 1492 had died from new diseases. Unfortunately, much of the evidence of large scale habitation in North America was plowed under to build farms. In South America the forest at least slowed the complete destruction of evidence.

      I suspect that as more of the Amazon gets scanned with lidar Carvajal will be vindicated.

          It's based on the fact that we don't know.

          We've seen multiple times in archeology when we've originally thought of places as "failed state" or "collapsed" it's actually turned out to be a conscious rejection of that way of life. Most famously Cahokia. Which at one point was a larger city than any city in Europe. We now know that it didn't "collapse" so much as there was a political revolution and people decided to move towards different ways of life.

          > A lack of resistance and no sanitation

          Precolombian north america actually had really sophisticated sanitation. In urban areas they pretty advanced waste management. In other areas, a lot of their seasonal mobility was possibly driven by sanitation needs. And they have really in depth practices around the ways they treat waterways and waste placement.

          The problem was actually the exact opposite. Compared to Europeans, they were obsessive about soap and cleanliness. But Europeans lived in really dense villages alongside their livestock for many generations and they suffered greatly from it. The history of Europe is basically one outbreak after another. But ofc over time some amount of immunities developed

          Maybe if North Americans had less sanitation and kept livestock they would've developed their own deadly diseases too that would've killed Europeans.

          • InTheArena 2 days ago ago

            This is commonly repeated, but if you go look at actual record keeping - at the history of early North American and Caribbean/Bahamas colonization through the period where there stopped being as much cross-cultural contact - we see epidemic after epidemic wipe our colonials as much as any. The mortality rate is staggering - even places that should have shown this the most - Haiti for example, the documented evidence was far closer to 100% mortality to Europeans, and significantly less for indigenous. Coming to Haiti during the Haitian revolution was a death sentence for all of the people who lived in squalor in one of the densest cities in Europe - Paris.

            Cultures coming together historically were deadly. There is a school of thought that argues that the Persian and Roman downfall was directly associated with the ability of diseases to transit roads.

            Of course, this is the stuff that we have records for. It's possible that there was a undocumented mass extinction event, But I tend to be skeptical of historical claims that are based on extremely localized and limited archeological projections.

            • culi 2 days ago ago

              Well regardless, we know North American natives had extensive sanitation practices and epidemics were quite rare. Syphilis, tuberculosis, intestinal parasites, and Chagas disease were all present but rarely turned into mass outbreaks.

                I didn;t say that it didn't - in fact, the reality was mass casulty events where common in a way that is unthinkable. We do _ in fact_ have plenty of mass graves for colonists. The lack of evidence of the same on the American Indian side makes me skeptical of the whole narrative.

                i think it's quite likely that the casualties where in similar scope across two different civilizations, but that the colonialists advantage (if you can call it such) of excess population and higher density of settlers, meant that the colonialists simply outlasted a far smaller population group.

                • ab5tract 2 days ago ago

                  You’re doing a lot of heavy lifting with this word colonist. The mass graves are either “imported criminal” (being in debt was a crime) or slave populations.

                  The North American cities were certainly more advanced in terms of sanitation than anything in Europe at the time. You had stuff like dual aquaducts differentiating drinking water from washing water and public cleaning crews and urban waste maangement and people bathed daily.

            Plenty of Native Americans (in both continents) survived the European diseases. but just looking at the North, the English colonists interacted heavily with Native Americans - hence the story of Thanksgiving. The "French and Indian War" pitted an alliance of the French and Indian nations against the English settlers.

            It was a deliberate genocide campaign in the 19th century (a good 300 years after initial European contact) that largely exterminated native cultures from what is modern USA.

            The current color of the continent is not some accident of "oh well we didn't know any better about disease". In Central and South America (and the far North), native cultures survived to a much greater extent and are still visible today.

          there are recorded incidents: https://project1492.org/small-pox-blankets/

          the controversy is mostly around whether or not it was a systemic, pervasive form of biological warfare. the evidence base is fairly small but needs to be considered in context of Native American cultural habits around durable recordkeeping (eg trade ledgers) vs colonial, and if colonists would record such an act

          there was also active ethnic cleanses and genocides committed by the US government repeatedly throughout US history too and those are very well documented, all dotted with stories as bad or actively and intentionally worse than biological warfare

          "He was speaking in opposition to a treaty that proposed the Cherokees sell off 20 million acres of homeland—a large portion of present-day Kentucky and Tennessee. This tension exploded with the commencement of independence hostilities in July 1776; some Cherokee leaders sided with the British, and in response the US charged thousands of colonial troops with “the utter extirpation of the Cherokee Nation.”

          https://sites.uab.edu/humanrights/2017/04/17/indian-removal-...

          "Throughout American history, the treatment of indigenous Native Americans has violated numerous articles of the United Nations Universal Declaration of Human Rights. These violations resulted in the loss of numerous Native American homelands, the Cherokee being only one example, and the genocide of numerous other smaller tribes since the beginning of European colonization. This is largely due to Eurocentric ideals, like the natural law of the Puritan worldview, which elevates the status of European peoples over that of indigenous, Native American peoples through a biased worldview. This mindset is so pervasive and powerful that it still prevails today, evidenced by modern films and television that paint Native American tribes as savage, ignorant and of ill intent toward the “white man”, and the policies of the current United States government."

            From your reference: "it is the colonizers who get to write the history"

            There's a simple explanation for this. The colonists were literate, and would keep diaries and write letters about their experiences. Churches would log births, deaths, and marriages. Printers would print newspapers. Later, these materials were fodder for academics who converted them into historical narratives.

            The Indians were not literate and so did not write letters and keep diaries.

            Even things like the number of Indians cannot be pinned down with any precision.

            • culi 2 days ago ago

              I don't think that's true. Mesoamerica had a very rich tradition of papermaking (Amatl) that predated paper in Europe (though probably not Chinese). Colonists severely repressed, criminalized, and even destroyed the paper and writing systems. Thousands of Maya codices were burned in 1562. Almost all pre-colombian libraries (amoxcalli) were destroyed

              We've deciphered Nahuatl and Maya script but Zapotec, Olmec, Isthmian, Quipu, and other scripts are still not well understood

              • curioadu 2 days ago ago

                The destruction during the Spanish conquests of the Aztecs and others was terrible. It was also rather disorganized initially, especially due to the huge delays regarding communication between the Americas and Europe.

                In regards to paper, while the Aztecs had impressive achievements, especially considering the almost complete isolation of the Americas from the rest of the world (is there any civilization close to the achievements of the Aztecs and other Amerindians in Africa south of Egypt?), are you sure that amatl/amate counts as paper? It was possibly stretched bark, and not woven.

                https://en.wikipedia.org/wiki/Amate#True_paper

                > The Maya used a writing material called huun starting from the 5th century. It was made from the inner bark of the wild fig tree. It was cut and stretched thin rather than made of randomly woven fibers, which according to one source, disqualified it as true paper.

                  Mali? Great Zimbabwe?

                  • desotus 2 days ago ago

                    The Mali Empire was not far south of Egypt, it overlapped with the Sahara and was relatively late, 1235-1610, and is primarily known for its rich natural resources, namely gold, which cannot be said to be an achievement. It was significantly large and did last for centuries, at least. It had lots of contact with others, such as regarding the empire more or less adhering to Islam. There are some mosques there, but some of them are adobe buildings, and some of them were reconstructed in the 1900s. Apart from gold, which is not an achievement, what achievements did the Mali empire have that comes close to that of the Aztecs and other Amerindians? Manding languages did not have their own script as far as I can tell, only Arabic and Latin.

                    .

                    Great Zimbabwe's Great Enclosure is something, but it seems much less impressive than that of for instance Chichen Itza, despite being younger. And Great Zimbabwe must have had international trade, given artifacts from China was found there. On the other hand, archeologists and Europeans accidentally damaged it, and time wore it down, and thus it might have been more impressive than the current ruins indicate. The building approach with small, mortarless stones, and wooden lintel instead of arches or huge stones, despite the time period being 1100s to 1500s, might have limited what could be constructed, but perhaps the original edifices employed other techniques as well than wooden lintel. Though I do not understand how the wooden lintel survived that many centuries. Dry climate?

                  Aksum for a start.

                  • curioadu 2 days ago ago

                    Aksum was more east of Egypt than south, right? And part of it lay in the Arabian Peninsula.

                    • graemep 2 days ago ago

                      More south than east.

                      It conquered part of the Arabian peninsula.

                      https://en.wikipedia.org/wiki/Aksumite_Empire

                      • desotus 2 days ago ago

                        It more or less bordered or was really close to Egypt, and it was on the very coastal edge of the African continent, as close as is possible to the Arabian Peninsula, and even conquered territory outside Africa. And if the conquered parts are included, it was somewhat east as well at the very least. Did it only conquer in that direction? There are the Adwa mountains (and even the active stratovolcano Adwa), somewhat separating Axum from its south-western direction further into Africa. The capital Axum was at a very high elevation in the highlands, like more than 2000 meters above sea level, and relatively close to the other major cities. Deserts might also have separated stretches of the empire to its west. It also must have had a lot of foreign influence, as per the Greek writing on some of its coins. And the capital Axum itself was relatively close to the coast. And one description I found just mentioned coastal or near-coastal Axum cities, not cities much further inland. Adulis was coastal, and Matara like Axum was not far from the coast. I do not know if it had any other cities. One source mentions Ptolemais Theron as a coastal city. And then some writers describe the Aksum empire as highly cosmopolitan, like Adulis having a large Greek population.

                        If it had partial natural borders like deserts, mountains and an active volcano, somewhat separating it from the rest of Africa in its south-western and western direction, and sizable numbers of Greeks and other peoples, and located on the very edge of Africa as close as possible to the Arabian Peninsula, it doesn't really seem to me to be the best example, upon closer examination. I can sort of understand why you would mention it as an example, though

              If 90+% of whatever society you are from was killed off by disease, and the people who came across the survivors treated them as little better than cattle and systematically destroyed any remaining trace of your society, how literate would history judge you to be?

              • parineum 2 days ago ago

                Literate has a definition that requires the ability to read and write. The North American native population was, by definition, illiterate. They had no written word.

                It doesn't mean they were stupid, they obviously picked it up quickly when they were exposed to it

            • paimapi 2 days ago ago

              the Native Americans were highly literate, they just didn't record granular details to ledgers because they didn't have strictly hierarchical institutions that utilized this data for controlling their population

              there is so much easily searchable resources for this and though it might not be your intent, your comment reads as willfully ignorant for being so broad and bought into the type of 16th century Puritan Eurocentrism that many of the articles above discuss in depth

                Highly literate? From your britannica reference:

                "No native writing system was known among Indigenous peoples of North America at the time of first European contact"

                And yes, I was referring to the North American Indians. I know the Mayans had writing. I even have a book on the Mayan writing system.

                > they didn't have strictly hierarchical institutions that utilized this data for controlling their population

                People did not write letters and keep diaries in order to control their population.

                The book "Empire of the Summer Moon" which is a history of the Commanche empire, and the book laments that their only sources were diaries and letters written by colonists.

                • curioadu 2 days ago ago

                  I wonder if one could group Central American and North-Central-American civilizations and peoples into two gross and very approximate groups:

                  1: Sedentary farmers like Aztecs and possibly Pueblos and those doing Three Sisters farming, some of them like the Aztecs having significant civilizational achievements all considered.

                  2: Hunting nomads, first doing fire-stick farming to create good conditions for hunting animals as well as gather certain plants, and later utilizing horses after their introduction from Europe.
