    Barely related but the headline reminded me of this video on the ontology of dogs and their infectious cancers.

    A bit of a dry subject to be sure, but I had never heard of infectious cancers before.

    In summary: a lot of information on how canines are related to each other. With a short segment how there is an infectious cancer found on dogs that is genetically different from any existing breed and as such could be considered it's own species.

      it is possible for an oncocyte [cancerous cell]

      to lose the features that define it as a subunit of tissue.

      in this case warts, or tumour cells may be transplanted during surgery, to a person that has nicked themselves with a scalpel or other such instrument, it is not impossible for a technician to have this happen while preparing a biopsy.

      the way a virus promotes cancer is by inserting, into genetic locus [address] that is close enough to the start of an "oncogene" that cancer results.

      biological development is a strange bird, for example a tumour with promiscuous histocompatability, that is still "a dog" from a genetic perspective.
