The article doesn’t come out and say it, but it’s the obvious conclusion.
The human family tree just got another — mysterious — branch, an African “sister species” to the heavy-browed Neanderthals that once roamed Europe.
While no fossilized bones have been found from these enigmatic people, they did leave a calling card in present-day Africans: snippets of foreign DNA.
There’s only one way that genetic material could have made it into modern human populations.
“Geneticists like euphemisms, but we’re talking about sex,” said Joshua Akey of the University of Washington in Seattle, whose lab identified the mystery DNA in three groups of modern Africans.
These genetic leftovers do not resemble DNA from any modern-day humans. The foreign DNA also does not resemble Neanderthal DNA, which shows up in the DNA of some modern-day Europeans, Akey said. That means the newly identified DNA came from an unknown group.
“We’re calling this a Neanderthal sibling species in Africa,” Akey said. He added that the interbreeding probably occurred 20,000 to 50,000 years ago, long after some modern humans had walked out of Africa to colonize Asia and Europe, and around the same time Neanderthals were waning in Europe.
In other words, Africans interbred with non-homo sapiens rather than maintaining reproductive isolation and evolving into a new species. The prehistorical Africans cursed themeselves, effectively reversing evolution on themselves, and in the modern day, race mixing with Africans by non-Africans is reversing evolution on one’s own family line. It is a crime against one’s ancestors.
