An ancient, shared set of human-specific genes underwent changes in a geographically isolated population after around 300,000 years ago, scientists say.

“The fact that we can reconstruct events from hundreds of thousands or millions of years ago just by looking at DNA today is astonishing,” stated Aylwyn Scally of Cambridge University. That sums up ...

New research reveals ancient humans in southern Africa lived in isolation for nearly 100,000 years. This led to unique ...

It seems that southern Africa provided an ecological refuge where people adapted successfully for more than 200,000 years – ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.
