A landmark genomic study published in Nature Genetics has analyzed 13,000-year-old human remains from the Montana Rockies, revealing a previously unknown genetic sub-pulse within the Clovis culture. The research, led by a global consortium of paleogenomicists, identifies a distinct lineage that diverged shortly after the initial entry of humans into North America, suggesting a more complex social and migratory landscape than previously modeled.
The study utilized high-coverage sequencing to pinpoint specific alleles associated with high-latitude cold resistance and respiratory efficiency. These findings provide critical evidence for how early Paleo-Indians adapted to the rapidly fluctuating environments of the late Pleistocene, rewriting the timeline of genetic diversification in the Americas.
