Scientists have conducted a high-resolution paleogenomic analysis on skeletal remains found near Hinkley Lake, dating back approximately 11,500 years. The study, published in Nature Genetics, reveals a distinct genetic pulse that does not match known Paleo-Indian groups, suggesting a "ghost lineage" that likely split from ancestral Beringians earlier than previously theorized.
This discovery challenges existing models of the early colonization of North America by showing more complex migration waves during the late Pleistocene-early Holocene transition. Researchers believe this group may have remained isolated in a glacial refugium before interacting with other expanding populations in the interior plains.
