Genetic analysis of modern humans found DNA suggesting we interbred with Neanderthals at least twice.
A genetic analysis of nearly 2,000 people from around the world indicates that such extinct species interbred with the ancestors of modern humans twice, leaving their genes within the DNA of people today.
Sarah Joyce and Jeffrey Long analyzed 614 sections of the human genome and created an evolutionary tree to explain the observed genetic variation.
The best way to explain the variations was if there were two periods of interbreeding between humans and an archaic species, such as Homo neanderthalensis or H. heidelbergensis.
