What can DNA tell us about the migration of the earliest modern humans and other hominins? In episode 98 of Parsing Science, we talk with João Teixeira from the University of Adelaide about his research which examined the genomes of modern humans to investigate the interbreeding between ancient humans and modern human populations who arrived in Southeast Asia around 60,000 years ago.  His article, “Widespread Denisovan ancestry in Island Southeast Asia but no evidence of substantial super-archaic hominin admixture,” was multiple coauthors and published on March 22, 2021 in Nature Ecology and Evolution.
