Scientists have way more DNA from ancient Europeans than Africans. Now analysis of a genome from nearly 20,000 years ago is answering questions about the continent’s past.
of the oldest African DNA is pushing back against this bias, and in the process revealing how our ancestors lived and moved around the continent tens of thousands of years ago. The findings add further evidence to the idea that, at some point around 20,000 years ago, some people in Africa started to come together in larger, more settled populations.
Thompson and her colleagues analyzed the DNA of 34 individuals—six of them for the first time—who lived in Africa between 500 and 20,000 years ago. By analyzing specific regions in these genomes, they were able to model how ancient populations may have moved around between 50,000 and 20,000 years ago.
Diyendo Massilani, a geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, says that these findings should lead to more work into ancient African DNA. “It’s proof that there is definitely potential in Africa—that we can find fossils, we can find DNA,” says Massilani, who was not involved with the research.

Donald Trump's DNA, Not Deposition, Sought in Defamation SuitA lawyer for a woman who accused former President Donald Trump of raping her in the mid-1990s and then filed a defamation lawsuit against him said Tuesday she will not seek to depose Trump prior to trial because it would cause unnecessary delay, but added that a DNA sample was still being sought.
