Are other races more evolved than Blacks?

It isn't hard. The vast majority of the DNA inherited from Neanderthals is the same as what we already have.

I'm going to make a couple assumptions here for the sake of making the math easy.

Assumption 1: Humans (and Neanderthals) split from chimps about 5 million years ago.
Assumption 2: Humans and Neanderthals split 500 thousand years ago.

So if the difference between humans and chimps is 1.2% the difference between humans and Neanderthals is about 1/10th of that or 0.12%. So if a human inherited 2% of their DNA from Neanderthals they got about 128 million pairs, but only about 153,600 of those pairs are different from human DNA. That's .002% of your 6.4 billion base pairs only accounting for about 1/5th of the difference between the populations discussed in my previous post.

I was asking you to explain why Africans don't have any of that Neanderthal DNA.

Africans living north, east and west of Sahara do have Neanderthal genes in amounts comparable to much of Euroasia population.     Africans living to the south of Sahara don’t.

The reason is simply.   For close to a hundred thousand years prior to the modern era, modern human migration and genes primarily flowed from south of Sahara northwards.      So Neanderthal genes, which l previously had primarily been found in Eurasia, were comparatively impeded from counterflowing south into subsahara Africa.

After the beginning of modern era and its globalization, undoubtedly Neanderthal genes carried by Euroasians have been flowing back into sub Saharan Africa at much greater rate than modern human genes have been flowing out of sub Saharan Africa historically.     But there have not been comparable amount of time, a few hundred years vs tens of thousands,  for the results of the counterflow to disseminate thoroughly into the sub Saharan population.
