New Type of Ancient Human Found—Descendants Live Today?

I do not disagree that OOA is a contending theory. The problem is with assuming that migration is the only explanation for the current genetic situation and that it is thus the necessary conclusion to draw from the available evidence.There are other ways of explaining the current genetic situation; the recent findings outlined in the OP suggest that those other ways may be more accurate than the current scientific community (OOA proponents) has thought.Jon

Wikipedia on Multiregionalism:

​

The hypothesis holds that the evolution of humanity from near the beginning of the Pleistocene two million years ago to the present day has been within a single, continuous human species. This species encompasses archaic human forms such as Homo erectus and Neanderthals as well as modern forms, which are held to be subspecies, and evolved worldwide to the diverse populations of modern Homo sapiens sapiens. The theory contends that there was some human genetic continuity in various regions of the world as well as gene interchange between the regions.

I've already addressed several of your points earlier on in the thread in replies to other members, especially Bluejay.I will add, however, that the 95% needn't happen over night. Given time and a continued disparity in population density, size, and centrality, one populations genetic information can certainly swamp out the information from another population, without super exoduses taking place from the former to the latter. As an additional tid bit, skeletal evidence seems to suggest that early sapiens in Europe share a larger number of Neanderthal traits than later sapiensi.e., the skeletal evidence seems to be of a 'transitional' sort:

Wikipedia on Lapedo Child:

​

The Lapedo child is a complete pre-historical skeleton found in Portugal. In 1998, the discovery of an early Upper Paleolithic human burial at Abrigo do Lagar Velho, by the team led by pre-history archeologist Joo Zilho, has provided evidence of early modern humans from the west of the Iberian Peninsula. The remains, the largely complete skeleton of an approximately 4-year-old child, buried with pierced shell and red ochre, is dated to ca. 24,500 years BP. The cranium, mandible, dentition, and postcrania present a mosaic of European early modern human and Neanderthal features. This (morphological) mosaic indicates admixture between late archaic and early modern humans in Iberia, refuting hypotheses of complete replacement of the Neandertals by early modern humans and underlining the complexities of the cultural and biological processes and events that were involved in modern human emergence.

In fact, much of the skeletal evidence we find continually draws the OOA model into question, as we find varieties of regionally continuous traits, seemingly 'transitional' varieties, etc. Now, as the OP brought up, even the genetic evidence is drawing the OOA model into question.Jon

Any on-off discontinuities are a) not inconsistent with MH, and b) not sufficient for speciation.Jon

I don't entirely understand the question. What do you want me to compare Africans, Neanderthals, etc. to? One another? Modern humans?Jon

But that is simply not true. Modern humans have maintained their identity as a single species for thousands of generations (even if we just start the count at AMH) despite the rarity and sporadicness of super exoduses and mass migrationsgenetic flow is clearly sufficient, since it's been the primary method for maintaining a mostly singular human identity for at least 60,000 years or so.Along with this, no groups have been found to be isolated long enough to diverge into entirely new specieson-off periods of connectedness to the main population permits genetic flow, which either swamps out their novelties or spreads them to the population at large, in either case preventing speciation of such groups.Such an isolation is necessary for OOA. What would have permitted this?Jon

Even if they show divergence, the present continuity of the genetic material of these ancient populations shows that the divergences weren't sufficient for speciation. That's all that's necessary for MH. My question was to point out that temporary isolation does not necessitate speciation. So long as any temporary periods of isolation do not produce speciation, then any such periods are not inconsistent with an MH model.MH does not require constant continuity.Jon

And so long as the inflow of African DNA is constant and large enough, that dilution is diminished over time. Hence why I pointed out apparent transitional skeletal evidence; these folk appear members of the 'diluted' generations.Jon

Is there any reason to believe such gene flow did not take place? And what sort of evidence leads you to conclude a divergence great enough for speciation? May I ask where you grabbed this number from and why you think this continuity of 350,000 years had to be seamless?Jon

I am not sure I understand the point you're trying to make. No one has ever denied the genetic dilution. And as the beneficial mutations spread through the peripheral populations, the number of genetically African based individuals would increase relative to the other members of the population, thus increasing the likelihood of an individual carrying African-based (sapiens) traits being mated with over another member of the population.Jon
