It’s difficult to study how ancient populations changed using the archaeological record alone. Here's a fascinating story about scientists sequencing and analyzing ancient DNA to trace human evolution. We learn that "Every person alive on the planet today is descended from people who lived as hunter-gatherers in Africa," and, when we compare the genetic research with the artifacts left behind, we learn a story of how "regionalization" affects cultural traditions and also the flow of genes.
Newly sequenced African aDNA shows dynamic ancient migratory patterns and interactions around the Later Stone Age that shaped human history.
