Most people alive today carry traces of genes inherited from Neanderthals -- the enduring legacy of prehistoric hookups with our extinct cousins. But researchers have long debated when and where that mingling happened, and whether these were one-off romps or commonplace trysts. Now, an analysis of ancient and modern genomes suggests contemporary people's Neanderthal DNA came from a single, prolonged period of mixing some 47,000 years ago...
To do that, Priya Moorjani, a population geneticist at the University of California, Berkeley, and colleagues analyzed previously sequenced genomes from 59 ancient H. sapiens, mostly from Western Europe and Asia, dating from between 45,000 and 2200 years ago. The oldest included DNA from Ust'-Ishim man in western Siberia (45,000 years old), the Czech Republic's Zlatý kůň woman (45,000 years old), and individuals from Bulgaria's Bacho Kiro caves (35,000 to 45,000 years old) and Romania's Peștera cu Oase caves (40,000 years old).
The researchers next identified regions of Neanderthal DNA in these ancient modern human genomes and in genomes from 275 present-day individuals from around the globe. Then, they used computer software to track the evolution of Neanderthal genes over time across the various ancient and recent populations, estimating approximately how many generations would be needed for the genomes to subtly diverge the way they did. Because the team included the ancient H. sapiens genomes, their analysis reached a level of precision that simply wasn't possible in earlier studies based primarily on contemporary genomes, McCoy notes.
Moorjani and colleagues conclude in the preprint that Neanderthal genes began flowing into the ancestors of people alive today about 47,000 years ago.

“Neanderthals predated recorded history by a lot”
They killed all the historians.
:-)
Africans have very little Neanderthal DNA (.3%) compared to Europeans (1-4%).
The little they have is likely from (relatively) modern breeding with Europeans.
Non-Africans are part Neanderthal, genetic research shows

I believe there's been some miscommunication between you and me. I was supporting the gist of the topic (increasing knowledge that sometime in the past there was some interbreeding among neanderthals). My point that there's a history of bestiality going back at least thousands of years ago was meant to suggest that it takes no small imagination to believe that human beings also got it on with neanderthals tens of thousands of years ago. Perhaps I didn't state that clearly.
It takes no small imagination to call them animals. No miscommunication, you’re a troll.
So the Neanderthals should get reparations
Is that a club in your pocket, or are you happy to see me??
You don't want to do that.
Because biggest body to brain ratio is in birds.
We come in second.
The bird's brain is mostly devoted to sharp, color sensitive vision. It apparently takes a lot of wetware to make that work. It is possible the Neanderthal brain size was for the same thing. Their eyes, were based on the averages of the remains we have found, larger then Sapiens. Tetrachromacy had to come from some where.
A meaningless example. Bird mass is low because it is designed (or evolved, doesn’t matter here) to fly. So any ratio is flawed.
Comparing a whale to a biped is poor enough, but at least they are both mammals.
Comparing two biped apes with 99+% dna overlap and the same basic niche is a fair bet.
We’re all God’s children in the dark.
Almost all of our behavior comes from culture, not biology, so we don’t have to worry about what we inherited biologically.
This stuff is interesting but can lead to unhelpful and even dangerous ideas.
Except in cases of severe abnormality, variations in the brain are totally leveled by our culture-dominant world. And our instructions are fairly simple.
History Debunked channel has good videos about this. Although i can’t find the one specifically where he talks about the particular gene combo that led to the explosion in art and invention.

Sure.
Neanderthals were not animals-they were human beings...
