Mating with Neanderthals and another group of extinct hominids, Denisovans, strengthened the human immune system and left behind evidence in the DNA of people today, according to new research.
Human history was "a lot more complex and interesting" than previously thought, Svante Paabo, director of the Department of Genetics at the Max Planck Institute for Evolutionary Anthropology, told Discovery News
While Europe and Asia might now be viewed as a hotbed of interbreeding, modern humans who stayed in Africa appear to have been active interbreeders as well. Neanderthals and Denisovans weren't present, but other archaic human groups likely were. "Well established is that modern Africans have greater genetic diversity, overall, than the modern populations of other continents," Parham said. "This greater diversity is likely due to what was inherited from earlier forms of Homo, combined with interbreeding between different forms of Homo."

If we are now accepting that interbreeding strengthened our immune systems then what else did it do???

Trust me. I have NO problem with you making this just a "white mans " story. I implore you to leave the rest of us humans out of it.
Don't you mean crossbreeding?
In my humble opinion, it did everything else as well. It helped a great deal with the whole process of evolution....
So is it even accurate then to consider us Homo Sapiens if all these species were interbreeding?
..."This confirms recent findings suggesting that the two populations interbred," Labuda was quoted as saying in a press release. His team believes most, if not all, of the interbreeding took place in the Middle East, while modern humans were migrating out of Africa and spreading to other regions.
The ancestors of Neanderthals left Africa about 400,000 to 800,000 years ago. They evolved over the millennia mostly in what are now France, Spain, Germany and Russia. They went extinct, or were simply absorbed into the modern human population, about 30,000 years ago.
Neanderthals possessed the gene for language and had sophisticated music, art and tool craftsmanship skills, so they must have not been all that unattractive to modern humans at the time....
The modern human/Neanderthal combo likely benefitted our species, enabling it to survive in harsh, cold regions that Neanderthals previously had adapted to.
"Variability is very important for long-term survival of a species," Labuda concluded. "Every addition to the genome can be enriching." news.discovery.com...

Sex With Neanderthals Made Us Stronger
Maybe, but it definitely created today's rednecks...

Any REDNECK farmer could tell you that. You want to line breed to establish a trait and out cross to add vigor to your line.
It is the idiot city folk with the fancy show stock who end up with weakly stock full of genetic defects like Wobbles or hip dysplasia.
