Scientists analyzing DNA from ancient and modern humans to create a ‘family tree of everyone’

Did you know that it’s now possible to sequence all of your DNA for about the cost of a smartphone? Unifying modern and ancient genomes Building on this approach, in our new research we describe the story of recent evolution among 215 diverse human populations from varying times and geographic locations. The genealogy – lines of descent from our common ancestors – includes the genomes of 3,601 people from three separate datasets, as well as eight high quality ancient genomes. The unified genealogy, or “family tree”, explains the genetic relationships of these thousands of genomes to one another. Comparisons involving non-African populations show that they have many common ancestors originating around 3,000 generations ago.
