Study Suggests Modern Humans Share DNA with Neanderthals

The study of Neanderthals has given thrilling new awareness among researchers, suggesting that Neanderthals and humans may belong to the same species. Research indicates that the two species coexisted for more than 1,000 years, with possible 'exchange of ideas' through imitation of each other's jewelry and stone tools. Studies also suggest that humans have Neanderthal DNA, and that the reason why some people are 'morning people' may lie in the genes of archaic humans such as Neanderthals. This has reignited a debate among scientists about whether Neanderthals should be considered to be the same species as early modern humans, and could reshape the history of human evolution. Some humans may have inherited their biological clocks from archaic humans through interbreeding. Recent discoveries are upending the view of Neanderthals as genetically inferior to modern humans, challenging the consensus that Neanderthals and Homo sapiens were separate species.
