Interbreeding and Human Ancestry

Recent genetic research reveals a complex history of interbreeding among modern humans, Neanderthals, and Denisovans, creating a rich tapestry of human ancestry. Specifically, multiple distinct Denisovan populations have contributed to the modern human genome through several separate interbreeding events, indicating that modern humans carry a genetic time capsule. Notably, all non-African individuals possess some Neanderthal ancestry, while populations like those in Papua New Guinea demonstrate the highest levels of Denisovan genetic contribution, with up to 5% of their genomes derived from these ancient hominins. This new understanding challenges the traditional view of human evolution as a linear process, emphasizing instead a web of complex interactions over time.
