    Neanderthal and Denisovan interbred with an archaic hominin

    See:
    https://www.biorxiv.org/content/10.1101/657247v1

    Since it's a pre-print the whole paper is available.
    "Abstract

    Previous research has shown that modern Eurasians interbred with their Neanderthal and Denisovan predecessors. We show here that hundreds of thousands of years earlier, the ancestors of Neanderthals and Denisovans interbred with their own Eurasian predecessors—members of a “superarchaic” population that separated from other humans about 2 mya. The superarchaic population was large, with an effective size between 10 and 46 thousand individuals. We confirm previous findings that: (1) Denisovans also interbred with superarchaics, (2) Neanderthals and Denisovans separated early in the middle Pleistocene, (3) their ancestors endured a bottleneck of population size, and (4) the Neanderthal population was large at first but then declined in size. We provide qualified support for the view that (5) Neanderthals interbred with the ancestors of modern humans.


    Author summary
    We show that early in the middle Pleistocene, long before the expansion of modern humans into Eurasia, the “neandersovan” ancestors of Neanderthals and Denisovans undertook a very similar expansion. In both cases, an African population expanded into Eurasia, endured a narrow bottleneck of population size, interbred with indigeneous Eurasians, largely replaced them, and split into eastern and western sub-populations. In the earlier expansion, neandersovans interbred with a “superarchaic” population that had been separate since about 2 mya and may represent the original expansion of humans into Eurasia."

    history repeats itself : the story of the 700 ka Neandersovans is similar to the story of the 50 ka modern humans

    So the Neandersovan was not Heidelbergensis or we dont know yet? They probably compared it with the genome of Atapuerca. Start to become very interesting.

    Interestingly enough recently this paper came out:
    https://advances.sciencemag.org/content/5/5/eaaw1268

    Article about it:
    https://www.smithsonianmag.com/scien...ght-180972184/

    Actually fits the timeline proposed in this paper.

    The Neanderthal & Denisovan samples we have are still very few. It is possible that they have only captured a fraction of genomic diveristy within and between these species.
