Neanderthals And Humans Interbred The prevailing belief was that homo sapiens ancestors first mingled with neanderthals in eurasia after a massive exodus from africa about 75,000 years ago. however, the startling revelations from this research expose a far more ancient narrative, one that traces back over 250,000 years, suggesting that early human dna flowed into neanderthals. The study found that humans left africa, encountered and interbred with neanderthals in three waves: one about 200,000 to 250,000 years ago, not long after the very first homo sapiens fossils.
Shock Discovery Humans First Interbred With Neanderthals 250 000 The researchers discovered that all sub saharan populations examined contained neanderthal dna, primarily from this interbreeding event 250,000 years ago. in some specific sub saharan populations, up to 1.5% of their genomes were comprised of neanderthal dna, inherited when humans with neanderthal genes migrated back to africa. As dr. akey and his colleagues reported on thursday, modern humans expanded out of africa and interbred with neanderthals between 200,000 and 250,000 years ago. but dr. akey’s team also found. “this is the first time that geneticists have identified multiple waves of modern human neanderthal admixture,” first of interbreeding: between 200,000 and 250,000 years ago and between. Neanderthals and anatomically modern humans initially interbred 250,000 years ago, a date that is far earlier than previously thought, a new study suggests. until now, neanderthals and.
