Nature article on DNA and Indigenous Americans

A new article published 22 April 2026 in Nature describes the Evolutionary History and Unique Genetic Diversity of Indigenous Americans. This is the largest genomic dataset of Indigenous Americans to date, helping researchers trace the threads of early migration across the Americas.

It will be interesting to see if this dataset improves future versions of ancestral regions reports from Ancestry, MyHeritage and others. These companies use reference populations in their models, and as the data improves, this can provide more accuracy to these ancestral regions reports.
