They Found 7,000-Year-Old Bones in the Amazon DNA Matched a Population From the Pacific Ocean

Researchers discovered 7,000-year-old human remains in the Amazon with genetic signals matching Pacific populations. This discovery challenges the traditional \"single arrow\" migration theory, suggesting a complex history of ancient seafaring, multiple migratory waves, and potential trans-oceanic contact, though scientists remain cautious due to the challenges of ancient DNA degradation and reference bias.
