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.

I like how they paint a picture of a neanderthal (much stronger and more powerful than homo sapiens) as showing up with a bouquet of flowers and a box of cholcoates to pick up his date for a romantic evening.
Methinks another scenario may have played out.
Neanderthals (homo sapien neaderthalis) were actually as intelligent, if not more intelligent, than homo sapiens sapiens.
The brain was certainly larger, anyway.
They were not, however, particularly good at having babies. (Possibly because the women were just as large as the men and tended to participate in hunts or war, going by bones evidencing damage, whereas modern humans divided up hunting/war and baby raising.)
Regardless, modern humans with Neanderthal in them, tend to be a tad smarter than average.
So, while I appreciate your post, it’s based on outdated information.
The opposite is true, I think.
Homo sapien sapien women (and men) were weaker and more easily taken.
The stone age was brutal.
“Since Neanderthals weren’t animals, it’s not surprising that it wasn’t mentioned.”
Neanderthals predated recorded history by a lot, which, historically speaking, is a relatively modern innovation.
Biologically speaking, Neanderthals were humans.
You give a neanderthal chick a string of beads, she’s yours.
If she didn’t beat your weak ass, maybe.
I can’t find the study, but the average Neanderthal woman (going by bone thickness) had a bench press north of 355.
LOL!!!
If "modern humans" and Neanderthals could have offspring which were able to have children of their own, doesn't that mean that they belonged to the same species?
It's not new that there was mating between modern humans and Neanderthals, but this study may put it at a much later date than had been guessed earlier.
The children resulting from such matings must have been accepted as members of the group by early modern humans--they weren't shunned.
I thought that, "biologically speaking" even homo sapiens (modern human beings) are animals. So it stands to reason to refer to neanderthals as animals too, however close one may think they were to homo sapiens. Yet they were different enough from homo sapiens IMHO for interbreeding with them to be remarkable, as in remarkably weird.
“Regardless, modern humans with Neanderthal in them, tend to be a tad smarter than average.”
Can you provide links to support that statement?
Regarding modern humans being weaker, I notice women tend to go for the big bad boys.
Hey, Friday night, closing time, dark cave. Why not?
So what’s your problem with the human mating with other animals?
How about you keep your troll behavior out of this topic?
That was obvious, but I was waiting for the troll’s other shoe to drop.
Those earings make her look so hot.
Little hint for ya: The Neanderthal were the intelligent ones. The Homo Sapiens were the idiot invaders.
First, Neaderthals not being stupid:
In a homo sapien sapien (modern human), brain size averages 1,270 cc for males and 1,130 cc for females. Neanderthals averaged 1,600 cc for males and 1,300 cc for females

Second, a little Neaderthal makes you smarter:

The second point is said quietly, because Europeans/Mesopotamians have much greater Neanderthal than the Africans, who have none. But you can go look at a bell curve of IQ by country and derive that on your own.
Now do body size to brain ratio and call me back.
