Another interesting find about human evolution

Just recently Newsweek had an article about how lice helped us understand human evolution better. It wasn't quite as new a concept as Newsweek made it appear - Sciencenews wrote about the subject in 2003 in an article called The Naked Truth? Lice hint at a recent origin of clothing, and the original 2003 study can be found here (use the links in the right-hand side). Still, it is and interesting article, and worth reading, even if the idea isn't as revolutionary as Newsweek wants to make you believe.

Now I see that Science Daily has an article about how tooth decay helps us understand it better as well.

Tooth Decay Analysis Supports 'Out Of Africa' Theory Of Human Evolution

A New York University College of Dentistry (NYUCD) research team has found the first oral bacterial evidence supporting the dispersal of modern Homo sapiens out of Africa to Asia.

Isn't it great with different branches of science work together? I am looking very much forward to eharing more about this study, and what it can tell us about our common ancestors.
