  • Earliest interbreeding event between ancient human populations discovered
    on February 20, 2020 at 7:12 pm

    A new study documented the earliest known interbreeding event between ancient human populations -- a group known as the 'super-archaics' in Eurasia interbred with a Neanderthal-Denisovan ancestor about 700,000 years ago. The event was between two populations more distantly related than any other recorded. The authors proposed a revised timeline for human migration out of Africa and into Eurasia. The method for analyzing ancient DNA provides a new way to look farther back into the human lineage.
