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

Originally Published 1 year ago — by Livescience.com

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.

"Revisiting the Origins of Homo sapiens: Insights from Genome Data and DNA Research"

Originally Published 2 years ago — by Reuters

A new study analyzing genome data from modern-day African populations has shed light on how Homo sapiens emerged and dispersed across the continent before spreading worldwide. The research found that multiple ancestral groups from across Africa contributed to the emergence of Homo sapiens in a patchwork manner, migrating from one region to another and mixing with one another over hundreds of thousands of years. The findings did not support a longstanding hypothesis that a single region in Africa gave rise to Homo sapiens or a scenario involving mixture with an unidentified closely related species in the human evolutionary lineage within Africa.
