Cavalli-Sforza, Menozzi and Piazza measured genetic differences between human populations using the fixation index in 1994 [1]. He was not ignorant of genetics, he just chose to shift attention to craniometry instead. And even now that we have far better tools and knowledge, people choose to focus on outdated arguments instead, because they give the answers they want. E.g. by bringing up Gould when his work is no longer relevant.
> To clarify, humans move around a whole lot more than most animals
By what mechanism do you think the visible physiological distinctions between human populations arose? Clearly humans don't (or haven't up to very recently) moved around enough to even them out.
You think those are the only traits that haven't been evened out?
