I don't see how one leads to another. The effect of living in Australia on a population of humans is entirely different than the effect of selectively being breeding dogs to be small and obedient. Just because both circumstances can exert selective pressure does not mean they are the same. Humans the world over, despite different geographies, have the same problems to contend with-- that's not the same thing as what we do when we selectively breed chihuahuas and great danes.

I’m not saying there are differences in (pick a trait, any trait). I’m saying that anyone who tells you that differences don’t exist has to prove it. Rice farming is a very different way of life to pastoralist is very different to hoe agriculture is very different to hunting and gathering. Some populations have been following the ~same lifestyle for over a thousand years. There’s no principled reason that can’t cause populations to diverge. If someone wants to say different populations are the same in some non-metaphysical way they need to prove it. They can’t just assert it. Religion works on faith. Scientists bring facts.

  The main reason differences don't exist is that the group of people they always want to claim has the differences (black people) aren't genetically related to each other and have more diversity than the rest of humanity.

  >Religion works on faith. Scientists bring facts. What does religion have to do with this? I didn't say to to rely on faith, rely on the scientific institution that already came to a concensus a long time ago. The studies are out there, if you want to see proof. Just because I don't have them on hand doesn't mean they don't exist and need to be taken on faith

    > Just because both circumstances can exert selective pressure does not mean they are the same. Selective pressure makes change. Different selective pressure makes difference. Reproductive isolation makes large differences possible. Humans have lived in very different environments and been reproductively isolated. There is no a priori reason to believe human populations are the same on every trait. And they’re not. Similar on most things but not on everything.
