@gcochran99 has a review of @carlzimmer's new book in @QuilletteM. Cochran wants to talk about race, & though he manages to talk around the topic, race & behaviour. He gets the issue wrong in an instructive way. @Anthrofuentes @hvierich @HollyDunsworth @Graham_Coop @geneticsODhttps://twitter.com/ent3c/status/1014852548380028929 …

Human cognitive evolution occurred within the same environment for at least a million years: the collective cognitive niche (culture).

Evolution among the ancestors of modern dogs [ wolves] occurred within the same environment for at least a million years , which is you can't even tell the difference between border collies and pit bulls.

That's sarcasm. There's no such thing as evolutionary momentum: if you split a population and expose the two daughter populations to different selection pressures, they start changing & diverging. It doesn't matter how long they were a single population before.

Surely you are not going to suggest a human requires a different cognitive suite to master living in New York or being literate or planting rice or looking after cows than they need to live in the Kalahari, or the Arctic and live in a forager culture?
