Yesterday I was notified that The Coming of the Thunder People had been published. I read the article with interest, particularly as it regarded two tribes I am personally connected with, the Chippewa I am related to by blood, and the Tlingit, amongst whom I was raised in Sitka, Alaska. Immediately after reading this article that pointed out the greater Denisovan admixture of the Tlingit and a few Algonquian tribes, the Ojibwa and Cree, I read of @jin-out's interest in the Tlingit and my knowledge of them.

This caused me to realize that the genetic legacy of Denisovan admixture in Native Americans could only be differentiated across the many tribes had some of that admixing happened after ~23kya, when the Siberian forebears of all Native Americans had emigrated to the Americas. If all the Denisovan admixture came from Siberian interactions, the amount of admixture in all the peoples in the Americas would be the same, because they all had the same forebears from Siberia. The only superable explanation for the roughly double dose of Denisovan ancestry in the Tlingit, Ojibwa, and Cree is that long after their ancestors had arrived in the Americas, and diverged into separate tribes from the original cohort, there had been additional admixture from N. American Denisovan sources.
While the Ojibwa and Cree are both Algonquian peoples, the Tlingit are not. It is likely that separate admixture events affect the Tlingit and Algonquian tribes, the latter whom could share such admixture event, being closely related. While I hunted, fished, worked, and partied with Tlingits, in my youth I was not interested in history, and their cultural heritage, which left me largely unaware of it except in particulars I gleaned from casual conversation with my friends, and the art and craft very present locally. Few would live in Sitka with it's many stunning Totem poles and never learn more about them, for example.
The Native American tribes most familiar to people, the Apache, Commanche, Navajo, Hopi, Cherokee, Iroquois, and etc., only share the genetic admixture with Denisovans common to Siberian peoples. Because all Native Americans descend from the initial immigrants from Siberia (according to the official anthropological narrative, backed up by genetic research), the ~double dose of Denisovan ancestry some tribes have did not derive from their roots in Siberia, but was acquired in N. America by those select tribes interbreeding with N. American Denisovans, otherwise it would be shown in all Native American tribes.
For a long time American archaeology officially claimed that no people lived in the Americas prior to ~13kya, when the glaciers had withdrawn enough to leave an ice free corridor between the eastern Laurentide ice sheet, and the Cordilleran ice sheet to the west. However, many well documented and solidly dated archaeological sites in the Americas are now known to be between 20ky and 30ky old. There are some few between 100ky and 250ky old, though these are not only disputed, but ridiculed today.
Denisovans are also said to have gone extinct tens of thousands of years before 13kya, and no one has officially acknowledged they once resided in the Americas. This differential admixture proves Denisovans did live in the Americas, and recently enough to mix with Native Americans after they emigrated from Siberia. This puts official American archaeology between a rock and a hard place, as they first have to admit that Denisovans did live in N. America, and then that they still lived in N. America when Native Americans arrived here. The later they claim Native Americans arrived, the later they must admit Denisovans yet lived, which contradicts the official archaeoanthropological narrative in all three regards. Denisovans are said to have diverged from the Neanderthals (whom we diverged from ~400kya) ~800kya, and could have easily been the humans responsible for sites in N. America 100ky or 200ky old - but the 'official narrative' scoffs at the possibility, and researchers who report such findings are blackballed, denied grant funding, their careers destroyed.
I only just realized it as I was writing this comment, because @jin-out asked me if I was related to the Tlingit (I hadn't yet learned of the book that has been written about it, because I hadn't finished the article in the first link. I have now). Denisovans are thought to have averaged above 7' tall, over 2M in height, and during the 18th and 19th Centuries, even into the early 20th Century, many skeletal remains of 'giants' were documented being found buried in the many mounds across N. America. Hundreds of newspaper articles discuss these archaeological finds at the time, and relate how museums were provided these remains for study, particularly the Smithsonian Institute founded by Ales Hrdlicka - who had proposed the Clovis First hypothesis that the Americas were only colonized after ~13kya.
No museum today admits to ever having received any of these skeletal remains, and the Smithsonian claims all the reports were hoaxes. Ales Hrdlicka was granted a lot of funding as a result of his popular Clovis First hypothesis, and this gave him a financial incentive to conceal evidence of prior population of the Americas the Denisovan remains provided. That popularity was why he founded the Smithsonian, in fact. However the very specific and limited admixture of Native American tribes with Denisovans proves that admixture happened long after the Native Americans arrived in N. America, because if it had happened in Siberia all Native Americans would have that admixture, all of them being descended from that initial emigration from Siberia and diverging into the hundreds of cultures they are now after arriving here.
Anyone familiar with the obvious disingenuity of historical and archaeological 'science' will note the congruence of the destruction of archaeological evidence of Denisovan civilization in the Americas with the false narratives crafted by copyist monks, whom deleted historical narratives and records and revised them according to their political loyalties, and the blatant concealment of facts regarding how the Pyramids and many megalithic sites were constructed, and by whom, ongoing today. While it is difficult to suss out the truth, it is almost impossible to fail to realize the false 'official narrative' Egyptology, particularly, attempts to impose.
The fact of the extensive mounds in N. America, the destruction of skeletons obviously likely to be Denisovan found in them, and the proven Denisovan genetic admixture that could only have resulted from interaction in the Americas after ~23kya, strongly suggests that H. sapiens acquired our civilization from our Denisovan forebears, and this is what fake history and archaeological narratives are concealing from us.
