sorry mike. My comment "there must have been some sudden change" was paraphrasing how biblically oriented people view evolution. In fact the article on the separation between chimps and humans suggests this took nearly four million years, hardly a sudden change. Therefore I agree totally with your comment above. The only minor disagreement I have would be that there are probably only five separate regional variations of humans. It's hardly an important disagreement. If you look at my previous postings on the subject you will see that I believe the biblical perspective has influenced the ready acceptance of the out of Africa theory. They believe there must have been a sudden leap at some time.

I actually reckon the white skin and blond hair of many Europeans goes back to Neanderthals. After all they lived for 200,000 years in a region of winter snow and they are not the only creature to change from white to brown with the seasons.
