A groundbreaking genomic study published in Cell Research has identified the highest levels of Denisovan DNA ever recorded in a modern human population—the Ayta Magbukun of the Philippines. The data suggests that multiple waves of interbreeding occurred between Denisovans and early modern humans in Island Southeast Asia.
The study provides a new timeline for human migration, suggesting that Denisovans were present in the region for hundreds of thousands of years before the arrival of Homo sapiens. This paleogenomic breakthrough offers clues into how ancient DNA helps modern populations adapt to local tropical environments and immune challenges.
