Hybrid Humans: Scientific Evidence Of Our 800,0... -

The "800,000-year" marker often refers to the estimated time when the lineage of Homo sapiens split from the lineage that led to Neanderthals and Denisovans. We shared a common ancestor—likely —around this time.

Perhaps the most intriguing part of the story is the evidence of "ghost" populations found in the genomes of West African groups. Computer modeling suggests that ancient humans in Africa interbred with a yet-to-be-discovered hominid group that split from our line hundreds of thousands of years ago. We have no fossils of them, only their "shadows" left in our DNA. Why It Matters Hybrid Humans: Scientific Evidence of Our 800,0...

Even after hundreds of thousands of years of separation, our biology remained compatible enough to merge back together when we crossed paths again. "Ghost" Populations The "800,000-year" marker often refers to the estimated
