Human Origins

Scientific American reports on a redating of two skulls from Ethiopia that push the earliest evidence for homo sapiens sapiens back to nearly 200,000 years. This puts the earliest fossil evidence in general agreement with dates derived from genetic studies. The theoretical significance of this early dating is that it widens the gap between the first appearance of modern human physiology and the emergence of modern human behavior. Check it out here.


There is an excellent article [actually a press release] on this subject with some nice accompanying photos here.
