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

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 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:

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:
