You better check on your facts. There is a race of humans who have no Neanderthal DNA. Don't believe the "tweaked" reports that they revised this year after the scientists tried to tell the truth.
Kind of like Galileo and his head on the chopping block for telling the truth about the Earth being round. That kind of stuff that's never changed.

It appears that you are wrong, that 'theory', that African's do not have neanderthal DNA has been disproven

As members of Homo sapiens spread from Africa into Eurasia some 70,000 years ago, they met and mingled with Neanderthals. Researchers knew that later back-migrations of Europeans had introduced a bit of Neanderthal DNA into African populations, but previous work suggested it was a just a smidgen. In contrast, modern Europeans and East Asians apparently inherited about 2% of their DNA from Neanderthals.
Previous efforts simply assumed that Africans largely lacked Neanderthal DNA. To get more reliable numbers, Princeton University evolutionary biologist Joshua Akey compared the genome of a Neanderthal from Russia’s Altai region in Siberia, sequenced in 2013, to 2504 modern genomes uploaded to the 1000 Genomes Project, a catalog of genomes from around the world that includes five African subpopulations. The researchers then calculated the probability that each stretch of DNA was inherited from a Neanderthal ancestor.
The researchers found that African individuals on average had significantly more Neanderthal DNA than previously thought—about 17 megabases (Mb) worth, or 0.3% of their genome. They also found signs that a handful of Neanderthal genes may have been selected for after they entered Africans’ genomes, including genes that boost immune function and protect against ultraviolet radiation. https://www.sciencemag.org/news/2020...eanderthal-dna
That was bad science. The redeeming value of science is that it is ultimately self-correcting.
It was widely held for a long time that species could not interbreed, and if they did, the off-spring would be sterile.
Both have now been proven to be false claims.
Species can and do interbreed, they do so far more frequently than previously believed, and the off-spring may be sterile or not.
