Ancient DNA Reveals the Two Origins of Humanity

For much of the 20th century, researchers assumed that modern humans emerged from a single ancestral population within Africa. But a groundbreaking new analysis—powered by advanced genome reconstruction and a novel computational framework known as COBRA—suggests a far more complex origin story. According to this new genetic model, Homo sapiens did not arise from one lineage, but from the long-term merging of two deeply divergent ancestral populations. These groups split from each other roughly 1.5 million years ago, evolving separately for over a million years before eventually mixing again around 300,000 years ago—well before our encounters with Neanderthals or Denisovans. The primary lineage appears to contribute nearly 80% of our genetic makeup, likely connected to hominins resembling Homo heidelbergensis. The second, making up roughly 20%, may represent a population with ties to Homo erectus. This ancient genetic blending may have shaped not only our physical traits but also aspects of our cognition and behavior. https://www.nature.com/articles/s4158... #HumanOrigins #AncientDNA #HomoSapiens #HumanEvolution #DNAResearch #COBRA #HomoErectus #HomoHeidelbergensis #Paleoanthropology #AncientHumans
