Ancient Mongolian cemetery reveals power and status mattered more than blood ties‎

On the edge of the Mongolian steppe, overlooking where two rivers meet, lies an ancient cemetery. Buried within are two families, traced through ancient DNA across six generations, surrounded by dozens of "strangers." The obvious assumption is that this was a family cemetery. But a recent study used machine learning and a technique borrowed from evolutionary biology to reveal that what really mattered was wealth, status and political power, not blood.
