Denisovan's tooth

Sexual relations between ancient humans and their evolutionary cousins are critical for our modern immune systems, researchers report in Science journal.
Mating with Neanderthals and another ancient group called Denisovans introduced genes that help us cope with viruses to this day, they conclude.
Previous research had indicated that prehistoric interbreeding led to up to 4% of the modern human genome.
The new work identifies stretches of DNA derived from our distant relatives.
In the human immune system, the HLA (human leucocyte antigen) family of genes plays an important role in defending against foreign invaders such as viruses.
The authors say that the origins of some HLA class 1 genes are proof that our ancient relatives interbred with Neanderthals and Denisovans for a period.

whereas the recent migrants from Africa wouldn't have had these genes,
Why not? Who says? They just drop a dubious fact into the mix without support or explanation.

“These factors include resistance to HIV replication within CD4 immune cells as well as a mutation, so far found only among Caucasians, in a receptor on immune cells that may make these cells tougher for the virus to infiltrate.”
Ever seen a beautiful woman with a butt ugly man?
It was a few years back in Louisville Kentucky. I met a family of Russian-Jewish immigrants. They had an attractive daughter in her early 20s but the entire family I swear to God had a lot of the physical attributes one thinks of as Neanderthal; the brow ridges, big noses, weak chins and stocky builds. I remember thinking at the time, 20 years ago, there must be an isolated village in Russia where Neanderthal survived.
Even with all these traits they were not unintelligent or unattractive. As a matter of fact I found the daughter very attractive.

Neanderthals are not a different species.
They are Homo Sapiens Neanderthalensis as compared to our Homo Sapiens Sapiens.
We are of the same species, different family, so there is no reason why they couldn’t interbreed.
I personally doubt they were really from a different family.
We were probably, maybe not quite, but as closely related as the different ethnicities are today.
Projectile weapons such as slings, atlatls, and bows probably made homo sap a superior fighter.
“our ancestors”
My understanding of genetics is that there is not just one genome,so to say “our ancestors” is introducing a universalism that is not warranted.
All the anti-white propaganda coming out of supposedly unbiased academia is sickening,and it`s been going on for decades.
I’m sure that helped.
But if they got a hold of you, you were screwed, in more ways than one. :)

So...you’re saying the Neanderthals were rich?
Possibly..! Lol They carried the biggest clubs around.

Thanks decimon. There were two other Neandertal articles online, not sure everyone would appreciate if I posted the accumulated backlog from last night's downtime though. ;')To all -- please ping me to other topics which are appropriate for the GGG list.The Neandertal EnigmaFrayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127] |

It’s sorta funny. A few years ago, not very many in fact, we were being assured that DNA testing positively PROVED that modern man and Neanderthals never mated AND couldn’t interbreed.
One theory advanced, if I recall correctly, was that modern men woukd have found Neanderthals sexually unattractive.
Seeing that men have been known to mate with walruses, I found that idea a little thin, myself.
