All Non-Africans Part Neanderthal, Genetics Confirm

https://i1.wp.com/www.africanglobe.net/wp-content/uploads/2013/07/All-Non-Africans-Have-Neanderthal-Dna.jpgIf your heritage is non-African, you are part Neanderthal, according to a new study in the July issue of Molecular Biology and Evolution. Discovery News has been reporting on human/Neanderthal interbreeding for some time now, so this latest research confirms earlier findings.

Damian Labuda of the University of Montreal’s Department of Pediatrics and the CHU Sainte-Justine Research Center conducted the study with his colleagues. They determined some of the human X chromosome originates from Neanderthals, but only in people of non-African heritage.

“This confirms recent findings suggesting that the two populations interbred,” Labuda was quoted as saying in a press release. His team believes most, if not all, of the interbreeding took place in the Middle East, while modern humans were migrating out of Africa and spreading to other regions.

The ancestors of Neanderthals left Africa about 400,000 to 800,000 years ago. They evolved over the millennia mostly in what are now France, Spain, Germany and Russia. They went extinct, or were simply absorbed into the modern human population, about 30,000 years ago.

Neanderthals possessed the gene for language and had sophisticated music, art and tool craftsmanship skills, so they must have not been all that unattractive to modern humans at the time.

“In addition, because our methods were totally independent of Neanderthal material, we can also conclude that previous results were not influenced by contaminating artifacts,” Labuda said.

This work goes back to nearly a decade ago, when Labuda and his colleagues identified a piece of DNA, called a haplotype, in the human X chromosome that seemed different. They questioned its origins.

Fast forward to 2010, when the Neanderthal genome was sequenced. The researchers could then compare the haplotype to the Neanderthal genome as well as to the DNA of existing humans. The scientists found that the sequence was present in people across all continents, except for Africa, and in aboriginal population of Australia.

“There is little doubt that this haplotype is present because of mating with our ancestors and Neanderthals,” said Nick Patterson of the Broad Institute of MIT and Harvard University.Patterson did not participate in the latest research. He added, “This is a very nice result, and further analysis may help determine more details.”

David Reich, a Harvard Medical School geneticist, added, “Dr. Labuda and his colleagues were the first to identify a genetic variation in non-Africans that was likely to have come from an archaic population. This was done entirely without the Neanderthal genome sequence, but in light of the Neanderthal sequence, it is now clear that they were absolutely right!”

The modern human/Neanderthal combo likely benefitted our species, enabling it to survive in harsh, cold regions that Neanderthals previously had adapted to.

I’m not a religious person, but I do believe that some amazing facts were handed down to us through history by the bible. It is my own theory that Neanderthals where the “giants in the earth” from Genesis 6:4. The word “giant” makes us think of “tall,” but the word can also mean very strong.

“There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.” – Genesis 6:4

In my view this sentence convoluted by history and various translations actually explains that  breeding with Neanderthal man (the very strong “sons of God”) resulted in new great physical strength for our species.

    Thank heavens we all have African in our blood lines! All of us coming from Africa.

    We do not know what a human/neanderthal hybrid would look like. Maybe at first they were very tall. Animal hybrids are often larger than their parent species. Take ligers for example…

      Good point! Keep in mind too that there are two ways to cross species. Tigons (female lion + male tiger) do not exceed the size of their parent species because they inherit growth-inhibitory genes from the lioness mother, while ligers (female tiger plus male lion) are much bigger than either patent. When male Homo sapiens first mated with female Homo neanderthalensis the offspring may have been like a tigon, a mix of both traits, but when a male neanderthal mated with a female sapiens the offspring might have been huge. The way genetics works, it could also be that only every once in a while that mix would produce giants, depending on if the mating male neanderthals had inherited particular genes.
