Ancient DNA analyses show that – unlike elsewhere in Europe – farmers from the Near East did not overtake hunter-gatherer populations in the Baltic. The findings also suggest that the Balto-Slavic branch of the Indo-European language family originated in the Steppe grasslands of the East.

In contrast to Western Europeans, new research finds contemporary East Asians are genetically much closer to the ancient hunter-gatherers that lived in the same region eight thousand years previously. 

Several major studies, published today, concur that virtually all current global human populations stem from a single wave of expansion out of Africa. Yet one has found 2% of the genome in Papuan populations points to an earlier, separate dispersal event – and an extinct lineage that made it to the islands of Southeast Asia and Oceania.

Using ancient DNA, researchers have created a unique picture of how a prehistoric migration route evolved over thousands of years – revealing that it could not have been used by the first people to enter the Americas, as traditionally thought.

Populations of hunter-gatherers weathered Ice Age in apparent isolation in Caucasus mountain region for millennia, later mixing with other ancestral populations, from which emerged the Yamnaya culture that would bring this Caucasus hunter-gatherer lineage to Western Europe.

New research dates plague back to the early Bronze Age, showing it had been endemic in humans across Eurasia for millennia prior to the first recorded global outbreak, and that ancestral plague mutated into its bubonic, flea-borne form between the 2nd and 1st millennium BC.
