Genetic data points to ancient liaisons between species.
Archaic humans such as Neanderthals may be gone but they're not forgotten — at least not in the human genome. A genetic analysis of nearly 2,000 people from around the world indicates that such extinct species interbred with the ancestors of modern humans twice, leaving their genes within the DNA of people today.
The discovery, presented at the annual meeting of the American Association of Physical Anthropologists in Albuquerque, New Mexico, on 17 April, adds important new details to the evolutionary history of the human species. And it may help explain the fate of the Neanderthals, who vanished from the fossil record about 30,000 years ago. "It means Neanderthals didn't completely disappear," says Jeffrey Long, a genetic anthropologist at the University of New Mexico, whose group conducted the analysis. There is a little bit of Neanderthal leftover in almost all humans, he says.
The researchers arrived at that conclusion by studying genetic data from 1,983 individuals from 99 populations in Africa, Europe, Asia, Oceania and the Americas. Sarah Joyce, a doctoral student working with Long, analyzed 614 microsatellite positions, which are sections of the genome that can be used like fingerprints. She then created an evolutionary tree to explain the observed genetic variation in microsatellites. The best way to explain that variation was if there were two periods of interbreeding between humans and an archaic species, such as Homo neanderthalensis or H. heidelbergensis.
"This is not what we expected to find," says Long.
Using projected rates of genetic mutation and data from the fossil record, the researchers suggest that the interbreeding happened about 60,000 years ago in the eastern Mediterranean and, more recently, about 45,000 years ago in eastern Asia. Those two events happened after the first H. sapiens had migrated

Well, I knew the HT pic would be before reply #10. She just fits into this thread.
Degenerates try to breed sheep and horsed also. One of the early DNA tests was contaminated with human DNA from the technician. There are not enough DNA tests to confirm this theory. Probably someone seeking money to keep his plush job.
They apparently still do. Got to any “peace” march and you can see the proof.
Presently they have been replaced by sheep!!!!
That's what I hear, anyway.
It would explain my high school football coach.
We’re on Post 26 already, and still no pic of the Michelle Wookie/chimp photo.
Genesis 6
1And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
2That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
3And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
4There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
That picture has been out there a long time and I don’t remember what it is based on but it usually has redder hair - what is called “the ginger gene.” Actually, it looks a lot like my adopted daughter but then red hair pops up in my extended family too. My only niece and four of my nephews all had red hair as toddlers and their kids are popping out with red hair.
That explains my ex-mother-in-law ...
Well, that explains my Ex-husband, LOL!
Ba-Dump-Dump! Thanks! I’ll be here all week. Try the veal and don’t forget to tip your waitress!
if wookies can breed with neanderthals... than anything is possible
All the features that are used to decribe Neanderthals can still be found in the human population today.
Although, you may be insulting the Ns. After all, their culture survived hundreds of thousands of years, whereas liberal destroy a culture in decades.
Also, their enemies and problems weren't susceptible to sweet talk and throwing money at them. They just wanted to eat ‘em. sort of like the Muslims, today
So many questions, but I need to stop laughing first.
Guilty.
