Ayta Magbukon inherited 5% genes from Denisovans. This exceeds Papuans by over 40%. Philippine Negritos admixed with Denisovans around 50,000 years ago. Denisovans settled Pacific islands over 100,000 years ago. Modern humans outnumbered Denisovans leading to their extinction. Ayta Magbukon minimally admixed with East Asian migrants preserving archaic DNA. Other Philippine Negritos diluted Denisovan ancestry through East Asian admixture. Europeans, Asians, Americans average 1-2% Denisovan DNA. Denisovans related to Neanderthals diverged from Homo heidelbergensis 300-400k years ago. Interbreeding occurred at multiple locations and times. No Denisovan skeletons found on Southeast Asian islands despite DNA evidence. Philippine Negritos comprise 25 subgroups on islands. Ayta Magbukon live on Bataan Peninsula Luzon. Denisovans confined to Eastern Eurasia with small populations. Modern humans carried Neanderthal DNA to Europe/Asia and Denisovan to East/Southeast Asia. Soil decay prevents Denisovan bone sequencing on tropical islands.
