Present-day Asians and Native Americans are descended from a group of people who were already in China 40,000 years ago, according to an analysis of fossil DNA published this week.
The genetic analysis showed that the early modern humans in Beijing had already diverged genetically from the ancestors of modern-day Europeans.
The researchers took nuclear and mitochondrial DNA from a leg bone found in the Tianyuan Cave in China in 2003.
Using this, they reconstructed the genetic profile of the leg’s owner, a person who lived at a very interesting time in the history of modern humans, the researchers said in a statement Monday.
“This individual lived during an important evolutionary transition when early modern humans, who shared certain features with earlier forms such as Neanderthals, were replacing Neanderthals and Denisovans, who later became extinct,” said lead author Svante Paabo, of the Max Planck Institute for Evolutionary Anthropology.
