Analysis of ancient proteins in Homo erectus teeth suggests that Denisovans interbred with this early human species, and that modern humans subsequently inherited some of this DNA through later interbreeding with Denisovans. The research uses protein analysis to overcome the limitations of ancient DNA degradation, providing new insights into human evolutionary history. This finding helps explain previously mysterious genetic contributions to both Denisovans and modern human populations.
Background
Modern humans interbred with archaic hominins like Neanderthals and Denisovans as they migrated out of Africa, and genetic evidence suggests these archaic groups also interbred with even earlier hominins. However, identifying these more ancient contributors has been challenging due to DNA degradation over time.
