１．The genetic affinity between southern Aborigines and Amazonian tribes suggests that human dispersal followed a clockwise coastal route.
２．It is crucial that neither Tianyuan man nor the “Sojin” lineages (ancestors of the Jomon people, related to the Onge)—both belonging to BEA—have been discovered in North America; they were likely overwritten by the subsequent influx of the Siberian Mal’ta lineage.
３．Since the Siberian ANA (Ancient Northeast Asians) could not have transitioned into a maritime population, the ancient South American Population-Y is theoretically most likely derived from the Japanese ” Sojin” lineages migrating southward along the coast.
