Europe's fourth ancestral 'tribe' uncovered (BBC)

Geneticists have detected a fourth ancestral "tribe" which contributed to the modern European gene pool.

Research shows Europeans are a mixture of three major ancestral populations - indigenous hunters, Middle Eastern farmers and a population that arrived from the east during the Bronze Age.

DNA from ancient remains in the Caucasus has now revealed a fourth population that fed into the mix.

Details are published in Nature Communications.

Researchers have now analysed genomes from two hunter-gatherers from Georgia that are 13,300 and 9,700 years old. The results show that these Caucasus hunters were probably the source of the farmer-like DNA in the Yamnaya.
