Ancient Spring - Invasion

The Ancient Beringian (AB) is a human archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site, dated to 11,500 years ago. The AB lineage diverged from the Ancestral Native American (ANA) lineage about 20,000 years ago. The ANA lineage was estimated as having been formed between 20,000 and 25,000 years ago by a mixture of East Asian (~65%) and Ancient North Eurasian (~35%) lineages, consistent with the model of the peopling of the Americas via Beringia during the Last Glacial Maximum.
