I have a lot to say about the new study of African genomes by Joseph Lachance and colleagues , which I think is tremendously exciting, along with the new preprint from Joseph Pickrell and colleagues on the arXiv, which includes some similar analyses with SNP data. But I'm on my way to Africa myself today for a week, and don't have time to post all my thoughts about the new papers until I arrive there. So I'll try to post these over the weekend.
For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.
From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.
The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.
