    Genetics Identifies New Human Ancestor

    New archaic, not Neanderthal, not Denisovan. This is just a first report in the popular press. More will come.

    Which hominin will be responsible this time if the Denisovans must've been in tropical Asia?

    Nobody knows yet. We have no sample of H. erectus DNA except maybe the snippet in Denisovan DNA and any other new creature is theoretical.

    Only the neanderthal admixture is correctly tied to a species, strange as it sounds. Denisova remains are non-diagnostic below genus Homo. Though its undemonstrated Greg Cochran's "mangani" must be something to do with the Iwo Eluru fossil site. And now the Andamanese have absorbed an unknown species of prehistoric man.

    The Denisovans are represented by a finger portion of a child and two molars. All of these bones exceed the dimensions of sapiens (if immaturity is taken into consideration) yet we do not have enough material to make a species call as we did with Neanderthals. There are plenty of species definitions but this is a finer point with genetics alone. If two species can be shown to have been separated for millions of years, say three million, then genetics has no problem with species designations. But if not, then they want to fall back on anatomy rather than make the call themselves.
