The Neanderthals, the Denisovans and Us
Recently published study in Nature shows not only multiple instances of Sapiens/Neanderthal crossover, but also a solid link to Denisovans. The link was found in Melanesian populations, a good distance away from the known Eurasian remains of Denisovan populations.
Not particularly new, but more confirmation of the interbreeding of modern humans and multiple co-existing offshoots. Very interesting stuff.

Although Neandertal sequences that persist in the genomes of modern humans have been identified in Eurasians, comparable studies in people whose ancestors hybridized with both Neandertals and Denisovans are lacking. We developed an approach to identify DNA inherited from multiple archaic hominin ancestors and applied it to whole-genome sequences from 1523 geographically diverse individuals, including 35 new Island Melanesian genomes. In aggregate, we recovered 1.34 Gb and 303 Mb of the Neandertal and Denisovan genome, respectively. We leverage these maps of archaic sequence to show that Neandertal admixture occurred multiple times in different non-African populations, characterize genomic regions that are significantly depleted of archaic sequence, and identify signatures of adaptive introgression. |
