# Ancient 'ghost lineage' in Africa contributed DNA to modern humans

Researchers have found evidence of a previously unknown ancient human population in Africa, often called a "ghost lineage," that interbred with early modern humans. This genetic signal, detected in modern DNA, adds a new layer to human origins beyond the known Neanderthal and Denisovan contributions. The finding reshapes our understanding of human evolution and the complex web of ancient interbreeding.
