DNA proves Black people are the only ones with 100% human DNA

For years, Black people have been seen and treated as less humans and in some cases were even called monkeys, but recent DNA study proves that Black people are actually the only ones with 100% human DNA.


A Harvard researcher has declared that Africans are the only race that has 100 percent human DNA while the rest have Neanderthal DNA in them (which makes them the closest relative to monkey)s. While this seems controversial another separate study colludes with the Harvard study.



Dr. David Emil Reich, a genetics professor at Harvard, and his colleagues analyzed the genetic variants of 846 non-African people, 175 people who live in the sub-Saharan region of Africa, and a 50,000-year-old Neanderthal man.


They have found out that nine genetic variants found in humans are associated with specific traits that can be found in Neanderthals. The same genetic variants are the same ones responsible for such diseases, such as Type-2 diabetes, Crohn's disease, lupus, optic disk size, and biliary cirrhosis.


The Harvard researcher and his team also found that this Neanderthal DNA affects how keratin filaments developed. As opposed to humans, Neanderthals have more keratin filaments than humans making their skin tougher. This allows them to survive in harsh, cold, climates. That DNA was beneficial to the human survival in such climates.


A separate study conducted by Dr. Benjamin Vernot and Dr. Joshua Akey from the University of Washington yielded the same conclusion after the scientists analyzed the genetic makeup of 286 East Asians and 379 Europeans.


According to the duo, Neanderthal skin genes are present in Europeans and East Asians. On the other hand, the rest of the genes are not compatible with the human genome and they most probably become extinct. One area of the human genome where the Neanderthal DNA is absent is that which affects human language and speech.


Harvard researcher DR. Reich said that the goal of the study is to understand how this DNA impact the biological impact of how human and Neanderthal DNA flow. It will also show the scientists what genes have been preserved and which ones have been rejected through the process of natural selection


It has more recently been discovered that all NON AFRICANS possess a small mixture of Neanderthal in their DNA. Studies have shown that once man began to migrate from East Africa and into colder climates, they interbred with Neanderthals, thus mixing the gene pool. It is hypothesized that Neanderthals evolved from Homo Heidelbergensis. Black Africans do not possess Neanderthal DNA because their ancestors did not migrate through Europe/Asia. In theory, Black Africans would represent pure modern Humans


Neanderthal Man died out about 30,000 years ago, but he left some of his DNA behind, especially in people scientists are delicately calling “non-African.” Neanderthals lived in Europe and Asia, but didn’t get to Africa. Early humans in Europe and Asia hooked up with the Neanderthals, so to speak, and although these were two different species, they were close enough genetically to have offspring, and some of those offspring (unlike, say, mules) were fertile. So Whites and Asians today have inherited 3 to 7 percent of genomes from Neanderthals.


Europeans looked down on Neanderthals—until they realized they shared their DNA


Once upon a time, scientists were convinced that Aboriginal Australians were further down the evolutionary ladder from other humans, perhaps closer to Neanderthals. In 2010 it turned out that Europeans are actually likely to have the most drops of Neanderthal blood, metaphorically speaking. In January 2014 an international team of leading archaeologists, geneticists, and anthropologists confirmed that humans outside Africa had bred with Neanderthals. Those of European ;6and Asian ancestry have a very small but tangible presence of this now-extinct human in our lineage, up to around 7 percent of our DNA.

People in Asia and Australia also bear traces of another known archaic human, the Denisovans. There is likely to have been breeding with other kinds of human as well. Neanderthals and Denisovans, too, mated with each other. Many in the deep past, it seems, were pretty indiscriminate in their sexual partnerships.

“We’re more complex than we initially thought,” explains John Shea. “We initially thought there was either a lot of interbreeding or no interbreeding, and the truth is between those goalposts somewhere.”

The discovery had important consequences. It raked up a controversial, somewhat marginalized scientific theory that had been doing the rounds a few decades earlier. In April 1992 an article had been published in Scientific American magazine with the incendiary title "The Multiregional Evolution of Humans." The authors were Alan Thorne, a celebrity Australian anthropologist, who died in 2012, and Milford Wolpoff, a cheery anthropologist based at the University of Michigan, where he still works today. They hypothesized that there was something deeper to human difference, that perhaps we hadn't all come out of Africa as fully modern humans after all.

However, Academics in the West and in Africa today generally accept that humans became modern in Africa and then adapted to the environments where they happened to move to fairly recently in evolutionary time—these are only superficial adaptations, such as skin color. But not everyone everywhere agrees. In China, there's a common belief among both the public and leading academics that Chinese ancestry goes back considerably further than the migration out of Africa.

"There are many people who are not happy with the idea of African origin,” Says Eleanor Scerri, an archaeologist based at the University of Oxford who researches human origins. “They have co-opted multiregionalism to make a claim that this is a simplistic idea, that races are real, and that people who have come from a particular area have always been there.” She tells me that this thinking appears to be prevalent not only in China but also in Russia. “There is no acceptance that they were ever African.”


For some, an unwillingness to accept African origins may be motivated by racism or nationalism, but this isn’t the case for all. There are those for whom it’s simply a way of squaring old origin stories with modern science. In Australia, for instance, many indigenous people favor the multiregional hypothesis because it sits closer to their own belief that they have been here from the very beginning. Indeed, this is an origin myth shared by cultures in many parts of the world.


But truth is, every human being on the planet today can be raced back to an African woman. Africans are simply the original modern humans.
