"DNA Study Reveals 3 Ancestral Groups Shaping Modern Japanese Population"

A new study suggests that modern Japanese people descend from three ancestral groups, including Neolithic Jomon hunter-gatherers, ancient predecessors of the Han Chinese, and an unidentified group with ties to Northeast Asia. The research also reveals genetic ties with Neanderthals and Denisovans, with inherited DNA linked to complex traits and diseases. The findings, published in Science Advances, provide valuable insights into the genetic and medical characteristics of the Japanese population and could contribute to the development of personalized medicine.
