Two Baby Girls, Who Lived and Died in the Last Ice Age, Reveal Lost American Ancestor Group

The two infants were ceremonially buried by a previously unknown population of ancient humans around 11,500 years ago. Their remains were found at Upward Sun River, a site in Alaska. DNA analyses show that the two girls were likely cousins, and descend from people separated from a population in eastern Asia, which remained isolated for thousands of years before migrating into Alaska, sometime after 15,000 years ago.

Named the Ancient Beringians — for the Bering Land Bridge that once connected North America to Asia — they were a “sister” population, or clade, that shared recent common ancestors with modern Indigenous North and South Americans. Their tool technology also appears to descend from Asian tools. Both the human remains at Upward Sun River and modern Native Americans were descended from the same ancestral source, which carried a mixture of East Asian and Mal’ta-related ancestry (the Mal’ta were an ancient population near Lake Baikal in modern Siberia, known largely from the remains of a four year old boy who died around 24,000 years ago).

Of course, all this latest find shows is that the Ancient Beringians existed about 11,500 years ago, and that they descended from the same group as modern Native Americans. We do not know what happened to this population after these two little girls died. This find does not tell us if the Ancient Beringians persisted, intermarrying with what would become modern North and South Americans. It does not tell us if they died out, perhaps because of climate change at the end of the Ice Age making their way of life untenable, or even because of conflict with other indigenous groups. These two young relatives raise many questions, and answer only a few.

historical-nonfiction:

The name jaguar is derived from the Native American word yaguar, which means “he who kills with one leap.”

tauntedoctopuses: It would be nice to know what specific Native American group/language this was from.

According to the Online Etymology Dictionary, jaguar comes from the Tupi word “jaguara.”

The Tupi were a large indigenous people in Brazil, who lived along the Atlantic coast and parts of the Amazon rainforest. Some of their words made it into Portuguese, including “jaguar,” from which it was borrowed directly into English. Save for a few isolated communities, the Tupi have been wiped out by Portuguese enslavement, European diseases, and ongoing assimilation.
