  • I apologize for the double reply, truly. Didn’t want to add a huge amount of text in an edit since I figured you’d reply quickly.

    I’ll summarize my rebuttal thusly, and you can decide for yourself if you want to continue.

    I think we’re arguing over the definition of species using two separate definitions. Encyclopedia Brittannica indicates that genetic species is a distinct definition from the definition of biological species.

    Is it fair to say that genetically these homonids are extremely closely related, but had distinct populations with distinct traits and morphology over time and across large geographies due to adaptive pressure?

    So then the debate centers on when or if speciation occured with each of those definitions, which I don’t think is a really productive exercise. We’re basically saying the same things just differently.


  • And apologies, I did you a disservice by not replying to your single citation.

    At the top of the definition:

    however. Some examples include the ecological species concept, which describes a species as a group of organisms framed by the resources they depend on (in other words, their ecological niche), and the genetic species concept, which considers all organisms capable of inheriting traits from one another within a common gene pool and the amount of genetic difference between populations of that species.

    The definition of genetic species are distinct due to more than just “can they successfully interbreed”. It’s more about their genetic drift and timeline.

    Your own text extraction says things like “usually” and “almost always”, because we have distinct examples of this happening over and over.

    Like most of science and nature it’s messy and categories are imperfect, but we use what we got to do the science we can.

    Annoyed or excited. Call it “stimulated”. Also often happens when they see a toy or a pounce target.

    Usually with domestic cats the ears being in a relaxed ‘up’ state show this cat is annoyed but not truly unhappy. Maybe even trying to wriggle away.

    Generally if you see highly dilated eyes and ears back, the cat is about to attack or pounce.

    However I’ll caveat that second part with the fact that it depends on the cat. I’ve seen cats maul from a submissive/passive position with ears up and eyes nearly closed. Like humans, every cat is different and every situation is going to be unique. They’re intelligent animals with unique personalities and nature/nurture, which is why they’re such excellent companions.
