Africans aren’t pure Homo Sapiens either (Archaic species interbreeding in Africa)



African ancestors interbred with Archaic species
Anatomically modern humans interbred with more archaic hominin forms even before they migrated out of Africa, a team of researchers has found. The discovery suggests genetic exchange with their more morphologically diverged neighbors was more widespread than previously thought and all humans today may carry genes from now-extinct Homo species.

When we discuss the origins of modern humans, the term ‘Out of Africa’ is a bit misleading. Our common ancestors came not from Africa as a whole but from a relatively small area somewhere in East Africa. Beginning around 80,000 years ago, this area was the scene of several population expansions that culminated in a ‘big bang’ c. 60,000 BP (Watson et al., 1997). This was a sustained expansion that pushed out of Africa and into Europe, Asia, Oceania, and the Americas.

These modern humans spread at the expense of more archaic ‘hominins’: Neanderthals in Europe and West Asia, and other poorly known groups elsewhere. But the latter were not totally replaced, as seen in the 1 to 4% Neanderthal admixture of present-day Europeans, East Asians, and Papuans. This has led some people to quip that only Africans are pure Homo sapiens:

Better yet, and a blow to Caucasian and Asian racists, the comparison of the human and Neanderthal genome makes it clear that it is only Africans who are 100 percent Homo sapiens, while in European (including American and Australian settlers) and Asian populations one can find up to 4 percent DNA stemming from the archaic and often maligned Neanderthal species – a hominid that went extinct more than 20,000 years ago. (Camphausen, 2010)

Well, no. Sub-Saharan Africans actually have more archaic admixture. The difference is that it came not from Neanderthals but from archaic groups within Africa. About 13% of the sub-Saharan gene pool comes from an earlier expansion of pre-modern hominins that occurred c. 111,000 years ago and seems to correspond to the entry of Skhul-Qafzeh hominins into the Middle East (Watson et al., 1997). This higher level of admixture may have come about because archaic Africans were behaviorally and physically closer to modern humans than the Neanderthals were.

Nonetheless, these ‘Paleoafricans’ were clearly archaic. They lacked something that modern humans had. What was this disadvantage that ultimately removed them from the struggle for existence? The answer is much debated, but most authors posit a limited capacity for symbolic thinking and social organization:

[…] the African exodus was predated by a cultural revolution involving new stone blade technologies, skin working tools, ornaments and imported red ochre […] More advanced symbolic systems in language and religious beliefs could have provided a competitive advantage to a group by promoting coordination and cohesion. (Atkinson et al., 2009)

Thus, when we discuss human origins, the real split was not between Africans and non-Africans but rather between two groups of Africans: archaics and moderns. Dienekes (2005) uses the terms ‘Paleoafricans’ and ‘Afrasians’:

It is common to distinguish between Africans and non-Africans, with the former being much more genetically diverse than the latter. But, the real “gap” in human origins seems to be between the really old Africans (“Paleoafricans”) and the rest (“Afrasians”).

The Paleoafrican element is entirely confined to Africa, while the Afrasian one is found in both Africa and Eurasia. Indeed, modern humans can be entirely split into two groups: (i) a group of “pure” Afrasians which includes all non-Africans, and (ii) a group of Afrasian-Paleoafricans which includes all non-Caucasoid Africans. Human groups of entirely Paleoafrican origin, unhybridized with the younger Afrasians are no longer in existence.

All of this leads to an intriguing conclusion. Since present-day sub-Saharan Africans were used as a benchmark to estimate Neanderthal admixture in present-day Eurasians, and since Paleoafrican gene sequences should be less ‘derived’ and more similar to Neanderthal gene sequences, Neanderthal admixture in present-day Eurasians is probably a bit higher than the estimated 1 to 4%.

  1. Weird video. But can this be the reason why we can not donate bone marrow between races?

  2. Seems like a lot of jealous and envious blacks making more racist comments below,,while the world invented everything in your sight,,and daily existence,most of you are still wearing cock socks,and chucking spears!!!So,what happened,???you need other cultures,and governance, for your survival and daily existence!!that's why your envious and jealous ,and a few of you moved forward,with our teachings,and schooling,and most of all,our generosities !!AND THE WHOLE WORLD KNOWS THIS,PEOPLE AROUND THE WORLD KNOW THIS!!!!!JUST KEEPING IT 100 PERCENT REAL!!!SO,YOU SHOULD RESPECT OTHER RACES,,PERIOD!!!!stop blaming others,you sorry ass losers!

  3. W W says:

    This would mean that native Americans, the last ones in the chain, are the most evolved. They would be ahead of the Chinese had they not been conquered and suppressed. Pyramids, math, science are some of the things they contributed. Incas had a huge civilization.

  4. Asians bred with denisovans…..

  5. I've never seen more hateful comments white and blacks being racist people thinking 4% neanderthal makes you a full blown ape even though every race has neanderthal in them can we all just live life and love each other pay taxes get amazing scores on our sats and act classes get into a really good college make alot of money a house get a car provide for a family even if you have 4% of something else in us we are all human do the same things look the same us stop being hateful.

  6. fert jurt says:

    slavic dna show romani gypsy state founded by the first romani king in europe.

  7. This is a bunch of Bs. They got the DNA from a South Carolina man and now created a whole scenario over something that is obliviously anomalous.

  8. No human comes from monkeys black or white and if we did they would have been made a beast by now in one of these secret government labs around here and they haven’t why because they cannot play God they can’t even make breast milk like a human mother because there is vitamins in nutrients that can only comes from the human breast it can’t be copied humans can only breed with humans period

  9. All this artificial intelligence is saying a whole lot of nothing trying to sound smart but sounds dumb instead

  10. Dave G says:

    50,000 years ago,Africans bread with REAL MONKEYS.A monkey like ansester callled( nigeris biglipes )came into to there cribs cuse it wanted some BUBBLE BUTT,BUBBLE BUBBLE BUBBLE BUTT.

  11. The only ones that hafe there own origin are the sans tribesmen in africa. Most others doo look it up. Some aboriginal australians hafe there own dna. Tells me somethings rong. Just a matter of time that they find out the native american indians were always here in america.did now the oldest bones hafe been found in japan. Look it up

  12. It's quite obvious from these comments that a little knowledge of genetics and history is a dangerous thing without the proper intellect and perspective to interpret it. It may be a mistake that scientists announce all their new discoveries to the general public.

  13. They can not get over that Neanderthal thing so here you have this bull shit pseudoscience!

  14. Ha ha ha you want to share your monkey genes.but not for us

  15. Oxtoa Wolf says:

    So Africans came from more primitive Africans okay. Does that mean their IQs actually improved from an even lower average? Evolution?……

  16. Max Maxim says:

    Right we have evolved just like everyone else

  17. Jay Seholm says:

    this is fucking bullshit

  18. Tam says:

    Ha ha ha! This just goes to show you how desperate the "white" (pink to be exact) devils are. Always comparing themselves to us Africans. We Africans are pure blood humans. You on the other hand are not humans. Just accept your inferiority and non-human status and deal with it. Synthing different materials with your fake robot voice just goes to show how desperate these animals are. I apologise to the animal kingdom because even animals are superior to you and deserve to be here unlike you – that's why you are dying off. You are not humans unlike us. Just accept your neanderthal non-human blood and degeneracy.

  19. Joe Duke says:

    But… Barrack Obama…. Usain Bolt … rappers…. ball players!! Booo hooooo.

  20. Lmao Afrocentrist are in denial of them being Neanderthals as well

  21. Video contradicts itself many times .

  22. Joe Soap says:

    This discovery sure seem to bother lot of people. Not sure why, doesn’t really matter where you come from but what you have accomplished, that should be what bothers them

  23. Clearly blacks are still black and nonblacks are not, also you all have animal FUR clear proof of human hybrids.

  24. Warning mass cancer (from all sides) below.

  25. No doubt. A Neanderthal produced this video. Geneticist have proved that Neanderthal DNA (2%-10%) have been found in every race, except Africans. That includes Caucasians. See National Human Genome Research Institute. Furthermore, Caucasians are only 6000 years old (see OCA2 gene). Original man (Africans) are millions of years old. These facts prove that out of Africa theory where Africans migrated then bred with Neanderthals is bullshit. Yet, Caucasians have African DNA? How did other races and Caucasians acquire Neanderthal DNA, but not Africans? Who created Caucasians?

  26. Sorry but when i hear robot voices I stop immediatly the video

  27. jim crow says:

    Why are Neanderthal people always shown wearing a fur loincloth and a rug? Euro/Asia was in an Ice Age, colder than Siberia or Canada today. Neanderthal's had needles and were able to make sophisticated weather resistant clothing. Stop spoon feeding us Bullshit.

  28. There was never a group of ape people ever to exist. All of this garbage is just a bunch of idiotic hogwash. All of this crap is useless information and it means nothing at all.

  29. Bob Aldo says:

    The very idea of "pure homo sapiens" is utterly absurd in any case.

  30. Do not forget the brood of vipers among you

  31. bikernvet says:

    what bullshit ! why are africans the dumbest race if they are so pure ?

  32. No such thing as mating with Archaic species. Different species cant produce viable offspring

  33. Boo Hefner says:

    Not even willing to watch this bullshit! You cave beast never stop with the lies! You're not human and we are, accept it!

  34. Wasp Pride says:

    Compare white success verses black. Lol.

  35. 23 Skiddoo says:

    Send in the kangz.

  36. LOL . This is stupid.

  37. Evolution has come a long way in a hundred and sixty years. Not one fossil link to establish a bull from its variant deposits.

  38. LMFAO…. African ppl are the ONLY pure human race of ppl left on the earth but you definitely tried it tho

  39. That’s only because they had started interbreeding with you Neanderthals/Cromagnons/Denisovans, etc., and taking upon themselves, some of your inherent genetic flaws, weaknesses and aberrations. None of that changes the fact that even now, the overwhelming majority of so-called ‘black’ Africans are human and genetically pure, despite the best efforts of the white/melanin recessive ‘species’ to deliberately ‘miscegenate’ us. You can blame our inherent genetic dominance for that. All it takes is the infusion of a relatively ‘un-miscegenated’ black man’s sperm to undo several generations of inferior white/melanin recessive genetic taint. This is a proven and irrefutable fact, and is precisely one of the many reasons why the white/melanin recessive species so fear, envy, hate and persecute members of the so-called ‘black’ race

  40. All this is bullshit.

  41. David Raye says:

    So what a small subset is not all Africans just as not all Caucasians have Neanderthal DNA and not all Asian's have Neanderthal or Denisovan

  42. Well, no hatred but Meiky, dear, honestly where would one begin to answer this hodge-podge of cherrypicking pseudo-science. If by "The Pop-Up Theory of New Species Creation" you mean the right mutated gene or genes created totally by CHANCE responding beneficially to some change in environment( weather, predators, new chemicals in your Pop-Tarts) then you aren't saying anything different than Darwinian Theory. Throwing, extraordinarily, complex String Theory and Quantum Physics into the mix of a biological process doesn't serve you well, Meiky. The Bhagavad Gita, notwithstanding, HOW do strings( different levels of sub-atomic vibration) serve to, instantly create groups, thousands of miles apart, so convergently genetically stable that they can get it on and produce viable offspring when they meet. How does this mechanism work or are you just manufacturing a disconnected garbage cluster of everything you're vaguely familiar with and creating a hypothesis??
    This video, itself filled with so many yet unproven assumptions and surmises ( listen carefully to how they present "facts"), is drawing an army of frenzied, silly, unscientific, sometimes vicious (not you, Meiky) responses out of the woodwork.

  43. 100% bullshit!
    “You read books and find statements that such and such a society or archaeological site is [claimed to be] 20,000 years old. We learned rather abruptly that these numbers, these ancient ages, are not known (speculations and imaginative guesses); in fact it is about the time of the first dynasty in Egypt that the date of any real certainty has been established.”

    – Dr Willard Libby, Nobel Prize winner who invented Carbon Dating and who also worked on The Manhattan Project

    “No matter how “useful” it is, though, the radiocarbon dating method is still not capable of yielding accurate and reliable results. There are gross discrepancies, the chronology is uneven and relative, and the accepted dates are actually selected dates. This whole blessed thing is nothing but 13th century alchemy, and it all depends upon which funny paper you read.”

    – Dr Robert Lee

    African Niggers are black Canaanites – period – fullstop – end of.

  44. The complexity of the DNA molecule, and the "code" within it, disproves the evolutionary theory.
    Only fools and rascals believe such a disproved theory.
