Stone Age people in northern Scotland buried related males — but not females — together in the same tomb, a new DNA study reveals, creating "webs of descent" across several Neolithic archaeological sites.
In the study, published Tuesday (April 14) in the journal Antiquity, researchers analyzed the DNA of 22 people from five tombs in the county of Caithness and the Orkney Islands in northern Scotland. The tombs were used between 3800 and 3200 B.C., when prehistoric Scotland was transitioning from foraging to farming.
