Many thousands? Scandinavia was iced over until about 9000 years ago, and
the ancestors of modern Scandinavians arrived there only about 4000-5000
years ago.

Charles Darwin presented a nifty one back in 1871 when he brought out _The
Descent of Man_; he called it sexual selection. (However, all of my
responses have been lifted from Jared Diamond's _The Third Chimpanzee_,
published in 1992 by HarperCollins of New York; the ISBN is 0-06-018307-1.)
