More of the same: getting down with the Denisovans

Researchers from Uppsala University have found evidence for genetic affinity between South East Asians and Denisovans. Instead of comparing whole genomes, they utilized genotype data for many populations and ran a sophisticated model to assess how ascertainment bias (i.e. rare SNPs not being included) could affect signals of archaic admixture. Their study included more than 1,500 samples from geographically disparate regions. Their results indicated genetic admixture among East Asians, and higher genetic affinity between Denisovans and Oceanians (previously known) as well as South East Asians.
