"Apparent variation in Neanderthal admixture among African populations is consistent with gene flow from Non-African populations.
oh did scientists say Nean DNA is found in all africans but to different degrees and foolshly explained it as gene flow from out of africa humans?
Further analyses suggest that these differences are likely due to recent non-African admixture in these populations. After accounting for recent non-African admixture, our results do not support the alternative model of older (e.g., >100 kya) admixture between modern human and Neanderthal-like hominid within Africa.
yes they did. yes they did

Did you even read the paper, or did you just see a title that you liked and quoted it? Here's the last line from the abstract from the paper you just cited:

No, they didn't. No, they didn't.

NO THEY DO NOT. the only person saying that is you. A small percentage of Khoisan have it but the vast majority of them do NOT. The information and citations have been provided in multiplicity. You simply don't read the info or just pretend it doesn't exist. I'm not sure which is worth. Don't you get wifi under your bridge?
Scientists believe humans evolved from ancestral primates in Africa several hundred thousand years ago, but it wasn't until approximately 65,000 years ago that they made their way out of Africa and into the Middle East and eventually the rest of the world. Until recently, that migration has been viewed by most scientists as a one-way trip. Gene studies over the past several years has turned that thinking around, however, as its been found that many people in several parts of Africa have European or Asian gene segments in their DNA. In this latest study, the researchers have found evidence of Eurasian genes in tribespeople who were thought to have a purely African ancestry.
Evolutionary Tree Information:
Both fossil and genetic evidence indicate that Neanderthals and modern humans (Homo sapiens) evolved from a common ancestor between 500,000 and 200,000 years ago. Neandertals and modern humans belong to the same genus (Homo) and inhabited the same geographic areas in Asia for 30,000–50,000 years; genetic evidence indicate while they may have interbred with non-African modern humans, they are separate branches of the human family tree (separate species).
In fact, Neandertals and modern humans may have had little direct interaction for tens of thousands of years until during one very cold period, modern humans spread across Europe. Their presence may have prevented Neanderthals from expanding back into areas they once favored and served as a catalyst for the Neanderthal’s impending extinction. Over just a few thousand years after modern humans moved into Europe, Neanderthal numbers dwindled to the point of extinction. All traces of Neanderthals disappeared by about 28,000 years ago. The most recently dated Neanderthal fossils come from western Europe, which was likely where the last population of this early human species existed.
Humans and Neanderthals may have coexisted in Europe for more than 5,000 years, providing ample time for the two species to meet and mix, according to new research.
Using new carbon dating techniques and mathematical models, researchers examined about 200 samples found at 40 sites from Spain to Russia, according to a study published Wednesday in the journal Nature. They concluded with a high probability that pockets of Neanderthal culture survived until between 41,030 and 39,260 years ago.
Although this puts the disappearance of Neanderthals earlier than some scientists previously thought, the findings support the idea that they lived alongside humans, who arrived in Europe about 45,000-43,000 years ago.
"We believe we now have the first robust timeline that sheds new light on some of the key questions around the possible interactions between Neanderthals and modern humans," said Thomas Higham, an archaeologist at the University of Oxford who led the study.
The fact thousands of apes remains found in any given pit a million year ago while ancient humans only a finger for dinosivan, a skeleton for Peking man, etc.

Evolution starts with the premise that life already exists. The scientific process used to describe how life began is called Abiogenesis and that is still only a hypothesis. Evolution could be the answer to how and god could very well be the answer to why since evolution doesn't address god in the slightest.
Abiogenesis & Evolution
The important thing to remember is that evolutionary theory is a scientific theory about how life has developed — this means that it begins with the premise that life already exists. It makes no claims as to how that life got here. It could have developed naturally through abiogenesis. It could have been started by a divine power. It could have been started by aliens. Whatever the explanation, evolutionary explanations begin to apply once life appears and begins to reproduce.
