    Some rare Y and mtDNA lineages from Beringia at the beginning of the Holocene

    You already posted the DNA you wanted in 2020, now you could tell where to look for it . Here is one:
    How to explain the gene flow eastwards and westwards from Bering Strait in the early Holocene, spreading the many arctic traits of the skulls of Native Asians and Americans today, and some rare Y and mtDNA lineages. These Y and mtDNA lineages for not having participated in the first waves that populated America had to be in a very restricted place away from the region of departure of these early Americans - arctic Beringia. In Beringia at the beginning of the Holocene which human groups have come up with new techniques for hunting, fishing or stone working, which would give them a decisive advantage to penetrate already occupied territories, what cultural innovations? Maybe you know, I confess my limitations. What I do know is that 11 Kya, though having a central lake, around a millennium, the Bering Strait was a narrow corridor of approximately 100 km around the Chukchi Peninsula in the arctic Beringia. Currently, even though we pushed marine mammals to near extinction and overexploited the remaining marine organisms, migrations in the Bering Strait alone in marine mammals (whales, seals, walruses and some polar bears) are estimated to be hundreds of thousands or even a million, not to mention salmon ... .11 Kya, since the oceans were almost virgin and the colder waters of the time produce more biomass, they would be incomparably more numerous, only a biologist can calculate. Calculate the easy fisheries in these bi-annual migrations on the fiord that linked the Arctic and the Pacific is more complex. In the initial channel only fish would pass, which would attract the polar bears, later the seals, the walruses and finally the whales. One whale supports a group of Inuit’s, almost a whole year. Gathering the other species, and the calculation of the number of inhabitants of this corridor should be in the order of millions, even discounting the part of this abundant fountain of resources (food and preserved foods; skins and bones to make the structure of kayaks and dog sleds; whale oil skins; walrus ivory for sculpting…) which would be exchanged for terrestrial mammal skins (the skins of marine mammals except polar bears either have no fur or are very thin). But land mammal skins were most likely to be obtained by warrior action, because the risky, aggressive, exploitation and conquest behaviors induced by this excess of animal protein do not fit in with negotiation and dialogue, nor would there be fur for such demand. These warrior expeditions to Alaska and Eastern Siberia also used to capture slaves who would work in the dangerous whaling. The centuries that lasted these fisheries around the Chukchi Peninsula must have deposited a lode of artifacts and human fossils on site, preserved with the help of the arctic climate (low temperatures and poor sediment production). To study this site, although the technology is not here yet (eventually it will be. We'll need remote-sensing technology similar to GPR that can be deployed under water to penetrate sediment and identify buried artifacts and features) we can identify shelter ports on the side fjords; sites of capture strategic (gorges through which the canal would pass; rocks over it), the attached beaches where the carcasses of the mammals would be dismantled and the attached caves, made on the permafrost (now filled with recent sediment) to store the oil and meat of the cetaceans. Most other places of human occupation will be close to these, preferably in sheltered places. Gorges are easy to identify, lie at the intersection of Quartzsite ridges or other hard rocks and the canal. The carved walrus ivory that may appear in adjacent archaeological sites of the time, in the Chukchi Peninsula and the interior of the continent, can tell us if the legends and gods of the region today are heirs of those of the past . Before being flooded the sides of this channel may also have been a slope used to crush herds. I have already sent this to the great lord of arctic archeology Vladimir Pitulko. Can you help advance the field work despite the glacial gravel and other sediments being heavy ?
