Yes. But back to the original thesis of the article ... I suspect the caveman preferred the blond because she was healthy and didn't have rickets, rather than that she was sexy because she was a blue-eyed blond.

Look, in an environment with a serious rickets problem the surviving population can either change its diet or become shorter (thereby requiring less vitamin D and calcium).

Sa'ami definitely changed their diet by adding reindeer to the normal table fare (although they each, supposedly, continue to carry around a fish for "emergency use" for dinner no matter where they might be).

The Inuit changed their stature ~ they really are short. Dwarfism is common with them. In fact, it's also common with the Sa'ami.
