Human Ancestors Had Sex with Now-extinct Relatives -
A new research indicates that our ancient human ancestors may have bred with a now extinct species of humanity before migrating from Africa to Eurasia.
Modern humans who are known as Homosapiens are now the only surviving species of humanity while other who once roamed the Earth, made their way out of Africa before humans did.
Recent genetic analysis of fossils from other ancient human species, such as Neanderthals in West Asia and Europe and the Denisovans in East Asia, have revealed that they once interbred with Homosapiens, giving modern humans genetic mutations that protected them as they began expanding across the globe about 65,000 years ago.
"We found evidence for hybridization between modern humans and archaic forms in Africa. It looks like our lineage has always exchanged genes with their more morphologically diverged neighbors," Michael Hammer of the University of Arizona told TG Daily.
Now scientists have made another discovery that may help them piece together the genetic lineage of modern humans. Researchers from the University of Arizona, who recently analyzed the human genome, discovered that our species mated with a previously unknown species of humanity before our ancient ancestors even left Africa with approximately 2 percent of contemporary African DNA perhaps coming from this lineage.
