Michael R. Waters commented that "To demonstrate such early occupation of the Americas requires the presence of unequivocal stone artifacts. There are no unequivocal stone tools associated with the bones... this site is likely just an interesting paleontological locality." Chris Stringer said that "extraordinary claims require extraordinary evidence – each aspect requires the strongest scrutiny," adding that "High and concentrated forces must have been required to smash the thickest mastodon bones, and the low energy depositional environment seemingly provides no obvious alternative to humans using the heavy cobbles found with the bones.
Recently, we carried out a stringent test of the null hypothesis of a single founding population of Central and South Americans using genome-wide data from diverse Native Americans. We detected a statistically clear signal linking Native Americans in the Amazonian region of Brazil to present-day Australo-Melanesians and Andaman Islanders ('Australasians'). Specifically, we found that Australasians share significantly more genetic variants with some Amazonian populations—including ones speaking Tupi languages—than they do with other Native Americans. We called this putative ancient Native American lineage "Population Y" after Ypykuéra, which means 'ancestor' in the Tupi language family.
According to the latest paleogenetic data, East Asian populations migrated to Northeastern Siberia ca. 20,000–18,000 cal BP. The migration was accompanied by their mixing with the descendants of the "Ancient North Siberians", represented by the genome from the Yana and Malta individuals. These processes were reflected in the Beringian tradition's wide proliferation in the region and led to the emergence of several ancestral lineages (Fig. 1) in Extreme Northeastern Asia: the Ancient Paleosiberian population represented by the genome of the individual from Duvanny Yar, and the ancestral Native Americans. The latter type subsequently divided into the Ancient Beringians and all other Native Americans (Moreno-Mayar et al. 2018; Sikora et al. 2019).
