Abstract

Different models have been proposed to elucidate the origins of the founding populations of America, along with the number of migratory waves and routes used by these first explorers. Settlements, both along the Pacific coast and on land, have been evidenced in genetic and archeological studies. However, the number of migratory waves and the origin of immigrants are still controversial topics. Here, we show the Australasian genetic signal is present in the Pacific coast region, indicating a more widespread signal distribution within South America and implicating an ancient contact between Pacific and Amazonian dwellers. We demonstrate that the Australasian population contribution was introduced in South America through the Pacific coastal route before the formation of the Amazonian branch, likely in the ancient coastal Pacific/Amazonian population. In addition, we detected a significant amount of interpopulation and intrapopulation variation in this genetic signal in South America. This study elucidates the genetic relationships of different ancestral components in the initial settlement of South America and proposes that the migratory route used by migrants who carried the Australasian ancestry led to the absence of this signal in the populations of Central and North America.

Fao  Karl.

That's amazing.

" introduced in South America through the Pacific coastal route"


Are they saying via the Bering straits or crossing the Pacific?

ROoA has it that the Sahulian element in Native Americans is via NE Asia (presumably by land through Beringia though there were certainly boats in Sahul within the last 50kya). Thus the Sahulian element was partly erased in North America by later Asiatic “migration” (gene flow through ordinary kinship relationships). Part of the ROoA dogma is that whenever possible, only “age of enlightment” Europeans has the ability to travel between continents. __________________________________________________________________________________________________Another possibility is intentional or waif travel directly from Sahul to the Americas very early. IMO Sahulian sealers living on the Greater Antarctica ice is the best explanation. During colder periods the sea ice (for people with small boats), was the most favorable place to live in the World. Seals were the greatest single mass of mammal flesh in the World, and there were marine plant and other marine resources. _________________________________________________________________________________________________People consider this impossible because Antarctica is so inhospitable now. However, the sea ice was much further out during cold periods, and in contact with much warmer water, with a much warmer climate than the Antarctic Coast today. _______________________________________________________________________________________________Relatively full blood Sahulians any place around NE Asia at any time is not evidenced either by the fossil record or genetics. Traces of Sahulian genes in early NE AMHS is due to gene flow out of Sahul such as post Toba. Not from some fantasy Sahulian population in the immediate area. However by invoking unevidenced essential replacements one can “prove” about any fantasy dogma in places and times for which there is little data. ______________________________________________________________Nor do ROoA paleoanthropologists know how to distinguish Sahulians from either Africans or Asians by fossils, so they are not in a position to know how poorly evidenced the hypothesis of Sahulians in NE Asia at any time is. Some how post WW II competency in understanding extant human systematics has become “racism”. Makes teaching and learning MUCH easier, but hardly leads to cogent understanding. ___________________________________________________________________________________________There even have been proposals from biological anthropologists that some how forensic anthropology should be banned (so that murderers can more easily get away with their crimes), because some how having the ability to know the geographic origins of humans remains is “racist”.  The Jomon clearly have some morphological affinities with Sahulians, but these are deep enough this is not detected in genetics for the most part (nor is the Jomon relationships with Europeans or other Asians detected yet in genetics).
