Diversity the key to human survival

Study Offers New Twist in How the First Humans Evolved

A new genetic analysis of 290 people suggests that humans emerged at various times and places in Africa.

...Dr. Scerri speculated that living in a network of mingling populations across Africa might have allowed modern humans to survive while Neanderthals became extinct. In that arrangement, our ancestors could hold onto more genetic diversity, which in turn might have helped them endure shifts in the climate, or even evolve new adaptations.

“This diversity at the root of our species may have been ultimately the key to our success,” Dr. Scerri said.
