Were Relations Between Neanderthals And Humans Hostile or Friendly – 1565 days old

Its not possible that they were friendly. That would be romantic and unrealistic assumption

Well it's not like there were warriors and warfare back then. Most likely men were horny and would fuck anything in those days, and who knows, they might have found Neanderthal women attractive or something, or vice versa (since it's we who have 1-4% Neanderthal admixture, it's quite likely that some Neanderthal males got very turned on by human women). And it could also be that human males got very tribal when they noticed Neanderthal males having sex with our women, and exterminated them over it.

You don't know what you're talking about. There are plenty of Neanderthal genes in modern populations. Actually, the majority of the Neanderthal genome can be found spread around in modern populations. The suggestion that hybrid males were sterile is based on two observations. Firstly, the Neanderthal admixture on the X chromosome is just one fifth of the admixture on the autosomes. Animal studies have shown that male infertility genes are especially prominent on the X chromosome (males have just one X chromosome, females have two). Secondly, genes expressed in testes show less Neanderthal admixture than genes expressed in any other tissue, further confirming that the fertility of hybrid Neanderthal-AMH males was significantly reduced (if not completely lost).

But, there is still clearly Neanderthal admixture in the autosomes, so hybrid females must have been fertile. And if the admixture initially occurred between Neanderhal males and AMH females, only the AMH mtDNA would be passed on to the hybrid females, who could then spread the Neanderthal genetic material to future humans. Males from future generations who inherited Neanderthal ancestry on certain X chromosomal genes, or genes expressed in testes, continued to experience reduced fertility, all the way to the present day.

Genes are in any part of your DNA thus they would be in any and all tissue of anyperson,so Neanderthal showing up less in testees doesn't make any sense at all.For example geneticists are using your spit not testees to point you have Neaderthal admixture.

Its ironic that you mention Neaderthal mtDNA hybrid expression would show up more in Neanderthal and Human hybrids, the funny thing is there has been no evidence of any Neanderthal mtDNA at all,I find it very hilarious because your point redundant.

However, recent computer models suggest the genetic similarities shared between Neanderthals and modern humans could also be due to the two species sharing a recent common ancestor rather than hybridization.

Compassion Helped Neanderthals Survive

They have an unwarranted image as brutish and uncaring, but new research has revealed just how knowledgeable and effective Neanderthal healthcare was.

The study, by the University of York, reveals that Neanderthal healthcare was uncalculated and highly effective – challenging our notions that they were brutish compared to modern humans.

The researchers argue that the care provided was widespread and should be seen as a “compassionate and knowledgeable response to injury and illness.”

Probably hostile, that's why Neanderthals are all dead.

The hostility must have increased as humans began spreading out more. Neanderthals had weird browridges with protruding bones, and probably (at least in some parts of Europe) much lighter skin, whereas the new homo sapiens immigrants were all super dark, so that must have resulted in a very real tribal conflict. However, at least initially, early contacts with Neanderthals and the first OOA group, must have had some sexual relations and minor gene flow to our ancestors.

You really think homo sapiens wiped out the Neanderthals? That would make sense, but it could also have been that Neanderthals really weren't that numerous, and were inferior hunters compared to homo sapiens, and they obviously didn't have agriculture to their advantage either (which humans lacked also when the last Neanderthal was extinct).

I remembered this story from my youth :-https://en.wikipedia.org/wiki/Neanderthals_in_popular_culture

In Poul Anderson's "The Long Remembering", a modern man undertakes a "mental time travel" enabling him to experience the life of a very remote ancestor, a Cro-Magnon hunter setting out to rescue his mate who was kidnapped by the "Goblins" (Neanderthals) living across the river. The story makes the startling assumption that blond hair and blue eyes were Neanderthal characteristics (which would imply that modern humans having such hair and eyes have more of a Neanderthal ancestry than others).
