Mutually beneficial partnerships between genomics researchers and North American Indigenous Nations are rare. Here, we present one such partnership that provides insight into the peopling of the Americas and furnishes a new line of evidence that can be used to further treaty and Indigenous rights. We show that the genomics of sampled individuals from the Blackfoot Confederacy belong to a previously undescribed ancient lineage that diverged from other genomic lineages in the Americas in Late Pleistocene times. Using multiple complementary forms of knowledge, we provide a scenario for Blackfoot population history that fits with oral tradition and provides a plausible model for the evolutionary process of the peopling of the Americas. One-Sentence SummaryPreviously unknown genomic lineage in North America revealed in present-day Indigenous community and historic ancestors.
