ancient family trees

Ancient DNA studies have moved on from finding out about amazingly old individuals. The latest thing is to sequence entire groups of humans who have been dead for centuries or even many millennia, and derive their family relations. A recent study of neolithic burial has set the record with a family tree connecting more than 60 individuals.

I used this as an occasion to round up a few other examples of family histories revealed by sequencing ancient DNA and to argue that, like ordinary family history, this is a way of unveiling the human histories that for one reason or another have remained hidden. My feature is out now:

Based on ancient DNA sequenced from 64 individuals buried at Gurgy, northern France, researchers have constructed the largest ever family tree of prehistoric people. The portraits are artistic impressions incorporating some details derived from the genome information. (Painting: © Elena Plain; reproduced with the permission of the University of Bordeaux/PACEA.)
