Explain this...

https://medlineplus.gov/genetics/underst...erthaldna/

"The percentage of Neanderthal DNA in modern humans is zero or close to zero in people from African populations, and is about 1 to 2 percent in people of European or Asian background."

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.

Probably the most likely explanation is that Neanderthals didn’t live in Africa.

Yeah, that's pretty simple. For there to be a defining genetic remnant there has to have been more recent or constant selective pressure, which would strongly imply an extant population to breed with. In the context of this thread..though, it's pretty strange all the way down to the bottom. HSN is a contemporaneous evolution with respect to HSS. Not a step on the way to us, or in any sense less evolved than ourselves. The origins of our revulsion to mixed race marriages may lie here, ironically.

There used to be more of us, we're all that's left.

Do you really need someone to explain why a population that never left Africa has no ancestors from a population that never lived in Africa? Since the answer to that is apparently yes I''ll add pictures. Maybe that will make it easier for you.

Here is what the currently known evidence tells us. It is subject to change if new evidence becomes available.

The earliest hominids are know to have left Africa at least 700,000 years ago. The only know evidence of this population was found in East Anglia, England. This population is thought to have died out leaving no modern descendants.

Another wave of hominids left East Africa 500,000 to 600,000 years ago. Populations from this wave eventually evolved into Neanderthals in Europe and Denisovans in Asia. Eventually some of the European Neanderthals also migrated to Asia where at least some of them interbred with the local Denisovan population. While all this was going on some portion of the population that was still in Africa got busy evolving into modern humans. This gave us four distinct populations. Neanderthals living in Europe, Denisovans living in Asia, a Neanderthal/Denisovan mix living in Asia, and modern Humans living in Africa.



Sometime before 40,000 years ago some of the modern humans left Africa again and migrated to Europe and Asia where some of them interbreed with the people that were already there. This left us with seven distinct populations. Modern Humans (in Africa, Europe, and Asia), modern/Neanderthal mix in Europe, modern/Denisovan mix in Asia, modern/Denisovan/Neanderthal mix in Asia, Neanderthals in Europe, Denisovans in Asia, and Denisovan/Neanderthal mix in Asia.



Eventually all the Neanderthal, Denisovan, and Neanderthal/Denisovan hybrids died out. This left us with modern humans living in Africa, in Europe, and Asia. Along with modern/Neanderthal hybrids living in Europe and in Asia. Modern/Denisovan and Modern/Denisovan/Neanderthal hybrids living in Asia.



This is why we have people in Africa with no Neanderthal or Denisovan ancestors. People in Europe with no Neanderthal or Denisovan ancestors. People in Europe with Neanderthal but no Denisovan ancestors. People in Asia with no Neanderthal or Denisovan ancestors. People in Asia with Neanderthal ancestors. People in Asia with Denisovan ancestors. And People in Asia with Neanderthal and Denisovan ancestors.

It also explains why while it currently looks like all native Americans migrated from Asia, about half of them have no Neanderthal or Denisovan DNA and the other half have both Neanderthal and Denisovan DNA. Their ancestors came from two separate populations in Asia.

Wah, wah, wah....the staff won't close this thread. Instead of letting it die a natural death, I'm gonna post in it every few days. The logic of Huggy.
