Not just Neanderthals: Ghost lineage in Africa left its mark on our DNA - Ars Technica

Core Impact Points

• The study found that a significant portion of modern humans in the US carry DNA from a previously unknown human lineage, which is estimated to have originated in Africa around 100,000 years ago.
• This 'ghost lineage' is thought to have interbred with modern humans, resulting in the transfer of genetic material from one species to another.
• The discovery has significant implications for our understanding of human evolution and the genetic diversity of modern humans, and may shed new light on the origins of human diseases.
• The study used advanced genetic analysis techniques to identify the presence of the 'ghost lineage' in modern human DNA, and found that it is present in individuals from diverse geographic and ethnic backgrounds.
• The researchers believe that the 'ghost lineage' may have played a significant role in shaping the genetic diversity of modern humans, and may have contributed to the development of certain human traits and characteristics.
