Neandertal and Denisovan Blood Groups Deciphered CNRS, July 28, 2021 Blood group analyses for three Neandertals and one Denisovan by a team from the Anthropologie Bio-Culturelle, Droit, Éthique et Santé research unit (CNRS / Aix-Marseille University / EFS) confirm hypotheses concerning their African origin, Eurasian dispersal, and interbreeding with early Homo sapiens. The researchers also found further evidence of low genetic diversity and possible demographic fragility. Their findings are published in PLOS ONE (28 July 2021). The extinct hominin lineages of the Neandertals and Denisovans were present throughout Eurasia from 300,000 to 40,000 years ago. Despite prior sequencing of about 15 Neandertal and Denisovan individuals, the study of the genes underlying blood groups had hitherto been neglected. Yet blood group systems were the first markers used by anthropologists to reconstruct the origins of hominin populations, their migrations, and their interbreeding.
