When scientists were doing it back in the 1800s it was all about racial purity. Otherwise where did all the oddball racial theories come from? I have no reason to think that it would be any different now. Human beings are sinful fallen creatures prone to the game of oneupmanship.

Oh...now I got you.

The 18th and 19th century scientists and non-scientists who were looking inbto this stuff were so backward in knowledge compared to where we are now and had such an uninformed social overlay that it's hard to make sense about what they said about human races. But I do see your point...

It all came from the eugenics movement. A lot of people noticed that you could improve a particular breed of horses or steer or dogs or whatever by selective breeding and the breed was then strengthened for whatever it was bred to do. Those scientists back then just wondered what would happen if the same selective breeding techniques were applied to humans. That's what they started out studying, what they ended up doing was stuffing whole categories of people into the ovens at Auschwitz. No good came of it.
