Ancient DNA Unveils Human-Neanderthal Interbreeding Timeline
TL;DR Summary
New research has refined the timeline of interbreeding between modern humans and Neanderthals, indicating it began around 50,500 years ago and lasted for about 7,000 years. This gene flow left non-African populations with 1-2% Neanderthal ancestry, contributing beneficial traits like immune resilience and skin pigmentation. The study also identified "Neanderthal deserts" in human genomes, areas devoid of Neanderthal genes likely due to lethal gene variants, enhancing our understanding of human adaptation and migration.
