This article I posted yesterday further complicates the issue:

Spread Of Modern Humans Occurred Later Than Previously Thought, Profs Say

"The spread of modern humans out of Africa occurred 40,000 to 50,000 years later than previously thought, according to researchers including one Texas A&M University anthropologist. "

Its an interesting puzzle.

I think with the techniques that archaeology and other sciences are now working with the answers will be forthcoming though.
