Chinese scientists have extracted DNA from the bones of people who lived 4,000 to 5,000 years ago, the state media reported on Monday.
The breakthrough signals the move of China's anthropological research from mostly observation-based studies to advanced DNA analysis, Xinhua news agency said.

Scientists of the Shanghai laboratory had three years ago recovered DNA from the bones of people who inhabited northwest China's Xinjiang Uygur autonomous region 3,200 years ago.
The study of the DNA led to the conclusion that Mongolians and Caucasians had once lived together.

“The laboratory is planning to establish a bone gene database of ancient Chinese,” the report said. Bureau Report
