Ancient Human Genome Throws New Light on Origins

September 29, 2014 12:31 pm | News | Comments

What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip of Africa tell us about ourselves as humans? A great deal when his DNA profile is one of the "earliest diverged"– oldest in genetic terms– found to-date in a region where modern humans are believed to have originated roughly 200,000 years ago.
