The new paper was published on Feb. 20, 2020 in the journal Science Advances and demonstrates the earliest known interbreeding event in Eurasia between ancient human populations known as the “super-archaics” with a Neanderthal-Denisovan ancestor – occurred about “700,000 years ago.”

Applying a new method for analyzing ancient DNA Dr. Rogers’ latest paper proves a mating event occurred between two populations that were “more distantly related than any other ever recorded,” and that scientists never knew about this early episode of interbreeding. Four proposed episodes of gene flow point to the hitherto unknown event some 744,372 years ago, suggesting interbreeding had taken place between super-archaics and Neanderthal-Denisovan ancestors “in Eurasia,” which suggests the timeline for humans migrating out of Africa and into Eurasia needs revision.

Studying genomes, the team of genetic scientists estimated that the super-archaic separated into its own species about two million years ago, which is supported with human fossil evidence in Eurasia that dates to 1.85 million years old. Nathan S. Harris and Alan A. Achenbach from the Department of Anthropology at the University of Utah, who also contributed to the study, said the first two human migrations into Eurasia occurred about two million years ago when the super-archaics migrated into Eurasia and subsequently expanded into a large population.

I think that was about a more recent interbreeding event.

1) Dates match.
2) “Out of Africa” matches.

I wonder with this interbreeding if both sexes mated with both sexes of each species and how they reacted when the babies were born.

Hmm.

Hmm.

Mixed race babies even today aren’t always accepted imagine mixed species children, obviously they survived but I wonder if at first they weren’t.

By definition, there’s no successful breeding between different species of animal. There’s some fuzz around the definition at the margins, but if there was large scale interbreeding between these various groups, then they were subspecies of a single species.

Knowledge of procreation is a rather recent development.

Yes I was wondering about that they have to be very similar genetically

Homo heidelbergensis was the common ancestor of the Denisovans and the Neanderthals.

>>This ghost species may have been late H. erectus, H. heidelbergensis, or a close relative. One or more late-surviving members of this ancient group met and mated with the ancestors of living Africans sometime in the past 124,000 years, the modern genomes suggest.<<

>>But Wall and others warn their methods cannot rule out that the “ghosts” could be one or several groups of modern humans in Africa that were separated from other moderns for so long that their genes looked “archaic” when the groups finally came together again and mixed. <<
