This study, led by my PhD student Jiaqi Yang, maps how Denisovan ancestry spread across Europe and Asia. We find several early Europeans with (trace amounts of) Denisovan gene flow, likely due to old migrations throughout Eurasia. There is no evidence of direct contact of Europeans with Denisovans
The first paper, lead by @arevsumer.bsky.social, Kay Prüfer and Johannes Krause, describes some amazing new genomes from Ranis and Zlaty Kun. See Arev’s write-up here:
The most surprising insight is that the Jomon, early inhabitants of the Japanese Archipelago, have much less Denisovan ancestry than all other East Asians - thus the Jomon (partially) descend from a lineage that predates the gene flow between modern-humans and Denisovans

The second paper is a systematic survey of Neandertal ancestry through time; a joint effort with @moorjanipriya.bsky.social ya.bsky.social’s lab at UC Berkeley, co-led by @leonardoiasi.bsky.social and Manjusha Chintalapati. Leo has a great summary of our main findings here:

Yang et al. study Denisovan ancestry in ancient and present-day humans. In contrast to other East Asians, genomic comparisons suggest that the Jomon derived most of their ancestry from a deep lineage…
Variation in Denisovan ancestry across East Asia reflects complex demography and multiple introgression waves. A new study reports that the Jomon population, early diverged ancient hunter-gatherers…
I am very happy to share our new paper on the genetics of some of the first modern humans who ever lived in Europe! We sequenced nuclear DNA from 13 specimens from Ranis in Germany, and found that they belonged to at least 6 individuals. www.nature.com/articles/s41... (1/n)

Gene flow from Neanderthals has shaped genetic and phenotypic variation in modern humans. We generated a catalog of Neanderthal ancestry segments in more than 300 genomes spanning the past 50,000 year...
Out today in @sciencemagazine, we've journeyed into our shared history with Neandertals by analyzing over 300 present-day and ancient modern humans, including 59 individuals who lived between 2,000 and 45,000 years ago.
