This eagle-taming huntress represents an enigmatic prehistoric people known as “Population Y”, whose existence has been inferred from traces of ancestry they left behind in the genomes of modern Australasians and some Native American groups in South America. It’s possible that the Population Y people migrated to the Americas millennia before the primary ancestors of modern Native Americans (the latter arriving around 15,000 years ago), and human footprints in New Mexico dated to 23,000 years ago may record their presence.
