Despite the fact that science shows the origin of man to be in Africa, there are those here who refuse to accept the probability that Africa may just have been a wee bit more advanced than Europe.

8 Incredible Things About Black Genetics That Will Amaze You

Back in 2008, a Cornell University study revealed that the genetics of Europeans have far more harmful mutations than people of African descent. These harmful mutations have continued to build up and continue to plague European bloodlines.
Black People Are Genetically More Diverse Than White People
The same Cornell University study also revealed that people of African descent had far greater variations in their genetics than their European counterparts.
Black Genes Prove the First Humans Are at Least 70 Percent Older Than Previously Estimated
After one African man, Albert Perry, passed away, researchers discovered an unusual distinct Y chromosome. While all humans had previously been traced back to one common ancestor, referred to as Adam, DNA technicians traced Perry’s lineage to a much earlier time. It means that Perry, and others with the same distinct Y chromosome, found in a small area of Cameroon, actually are not descendants of “Adam.” Their origins push the dawn of humanity back from 140, 000 to 338,000 years ago — or 70 percent earlier than previously estimated, according to the study.
Black Babies Advance Earlier and Faster Than European Babies
In The Developmental Psychology of the Black Child, Dr. Amos Wilson analyzes studies conducted by white social scientists that revealed significant differences in how quickly Black babies seemed to develop compared to European babies. The study found that at only 9 hours old African babies were able to prevent their heads from falling backwards. It took European babies roughly six weeks to accomplish this. By the time African babies were 11 months old, they were able to climb the steps alone while European babies typically didn’t accomplish this until they were 15 months old. The study focused specifically on African babies, but Wilson explains that the same trends were also found to be true in Black children of other nationalities.
Some African Genes Represent a More Complex Image of the Evolution of Modern Humans
In 2011, researchers discovered human fossils from a Nigerian site called Iwo Eleru. The fossils turn out to be an incredibly rare mix of ancient and modern features, which suggests that this was the result of breeding between archaic and modern humans. According to Chris Stringer of the Natural History Museum in London, this is a sign of a “more complex scenario for the evolution of modern humans in Africa.”
The Miracles of Melanin
The very pigment that gives Black people their skin complexion is the source of many miraculous health benefits. Melanin provides incredible protection against the negative effects of ultraviolet radiation, neutralizes harmful effects of others forms of radiation, fights off signs of aging and so much more. Perhaps even more astounding is melanin’s unique ability to absorb certain energy sources such as light and sound waves, and convert them into reusable energy.
West Africans Are Genetically Better Sprinters
James M. Tanner, the author of The Physique of the Olympic Athlete, pointed out the major racial differences among athletes in the Olympics and discovered that there is a reason so many of the top track and field competitors are of African descent. Studies revealed that the muscle composition of West Africans genetically allows them to be “the most anaerobically efficient athletes” due to the way their bodies process energy.
Kenyans Are Genetically Proven to Have High Endurance
Recent studies revealed that Kenyans have “little ammonia accumulation in their muscles from protein combustion and less lactic acid buildup. They have more of the muscle enzymes that burn fat, and their glycogen reserves are not burned as quickly, which improves endurance.”

Whites Genetically Weaker Than Blacks, Study Finds
White Americans are both genetically weaker and less diverse than their black compatriots, a Cornell University-led study finds.
Analyzing the genetic makeup of 20 Americans of European ancestry and 15 African-Americans, researchers found that the former showed much less variation among 10,000 tested genes than did the latter, which was expected.
They also found that Europeans had many more possibly harmful mutations than did African, which was a surprise.

How Europeans evolved white skin
How Europeans evolved white skin
By Ann Gibbons
Common European traits like pale skin evolved relatively recently in central and southern Europe.
Most of us think of Europe as the ancestral home of white people. But a new study shows that pale skin, as well as other traits such as tallness and the ability to digest milk as adults, arrived in most of the continent relatively recently. The work, presented here last week at the 84th annual meeting of the American Association of Physical Anthropologists, offers dramatic evidence of recent evolution in Europe and shows that most modern Europeans don’t look much like those of 8000 years ago.
The origins of Europeans have come into sharp focus in the past year as researchers have sequenced the genomes of ancient populations, rather than only a few individuals. By comparing key parts of the DNA across the genomes of 83 ancient individuals from archaeological sites throughout Europe, the international team of researchers reported earlier this year that Europeans today are a mix of the blending of at least three ancient populations of hunter-gatherers and farmers who moved into Europe in separate migrations over the past 8000 years. The study revealed that a massive migration of Yamnaya herders from the steppes north of the Black Sea may have brought Indo-European languages to Europe about 4500 years ago.
Now, a new study from the same team drills down further into that remarkable data to search for genes that were under strong natural selection—including traits so favorable that they spread rapidly throughout Europe in the past 8000 years. By comparing the ancient European genomes with those of recent ones from the 1000 Genomes Project, population geneticist Iain Mathieson, a postdoc in the Harvard University lab of population geneticist David Reich, found five genes associated with changes in diet and skin pigmentation that underwent strong natural selection
First, the scientists confirmed an earlier report that the hunter-gatherers in Europe could not digest the sugars in milk 8000 years ago, according to a poster. They also noted an interesting twist: The first farmers also couldn’t digest milk. The farmers who came from the Near East about 7800 years ago and the Yamnaya pastoralists who came from the steppes 4800 years ago lacked the version of the LCT gene that allows adults to digest sugars in milk. It wasn’t until about 4300 years ago that lactose tolerance swept through Europe.
When it comes to skin color, the team found a patchwork of evolution in different places, and three separate genes that produce light skin, telling a complex story for how European’s skin evolved to be much lighter during the past 8000 years. The modern humans who came out of Africa to originally settle Europe about 40,000 years are presumed to have had dark skin, which is advantageous in sunny latitudes. And the new data confirm that about 8500 years ago, early hunter-gatherers in Spain, Luxembourg, and Hungary also had darker skin: They lacked versions of two genes—SLC24A5 and SLC45A2—that lead to depigmentation and, therefore, pale skin in Europeans today.
But in the far north—where low light levels would favor pale skin—the team found a different picture in hunter-gatherers: Seven people from the 7700-year-old Motala archaeological site in southern Sweden had both light skin gene variants, SLC24A5 and SLC45A2. They also had a third gene, HERC2/OCA2, which causes blue eyes and may also contribute to light skin and blond hair. Thus ancient hunter-gatherers of the far north were already pale and blue-eyed, but those of central and southern Europe had darker skin.
Then, the first farmers from the Near East arrived in Europe; they carried both genes for light skin. As they interbred with the indigenous hunter-gatherers, one of their light-skin genes swept through Europe, so that central and southern Europeans also began to have lighter skin. The other gene variant, SLC45A2, was at low levels until about 5800 years ago when it swept up to high frequency.
The team also tracked complex traits, such as height, which are the result of the interaction of many genes. They found that selection strongly favored several gene variants for tallness in northern and central Europeans, starting 8000 years ago, with a boost coming from the Yamnaya migration, starting 4800 years ago. The Yamnaya have the greatest genetic potential for being tall of any of the populations, which is consistent with measurements of their ancient skeletons. In contrast, selection favored shorter people in Italy and Spain starting 8000 years ago, according to the paper now posted on the bioRxiv preprint server. Spaniards, in particular, shrank in stature 6000 years ago, perhaps as a result of adapting to colder temperatures and a poor diet.
Surprisingly, the team found no immune genes under intense selection, which is counter to hypotheses that diseases would have increased after the development of agriculture.
The paper doesn’t specify why these genes might have been under such strong selection. But the likely explanation for the pigmentation genes is to maximize vitamin D synthesis, said paleoanthropologist Nina Jablonski of Pennsylvania State University (Penn State), University Park, as she looked at the poster’s results at the meeting. People living in northern latitudes often don’t get enough UV to synthesize vitamin D in their skin so natural selection has favored two genetic solutions to that problem—evolving pale skin that absorbs UV more efficiently or favoring lactose tolerance to be able to digest the sugars and vitamin D naturally found in milk. “What we thought was a fairly simple picture of the emergence of depigmented skin in Europe is an exciting patchwork of selection as populations disperse into northern latitudes,” Jablonski says. “This data is fun because it shows how much recent evolution has taken place.”
Anthropological geneticist George Perry, also of Penn State, notes that the work reveals how an individual’s genetic potential is shaped by their diet and adaptation to their habitat. “We’re getting a much more detailed picture now of how selection works.”

The study focused specifically on African babies, but Wilson explains that the same trends were also found to be true in Black children of other nationalities.
Some African Genes Represent a More Complex Image of the Evolution of Modern Humans
In 2011, researchers discovered human fossils from a Nigerian site called Iwo Eleru. The fossils turn out to be an incredibly rare mix of ancient and modern features, which suggests that this was the result of breeding between archaic and modern humans. According to Chris Stringer of the Natural History Museum in London, this is a sign of a “more complex scenario for the evolution of modern humans in Africa.”
The Miracles of Melanin
The very pigment that gives Black people their skin complexion is the source of many miraculous health benefits. Melanin provides incredible protection against the negative effects of ultraviolet radiation, neutralizes harmful effects of others forms of radiation, fights off signs of aging and so much more. Perhaps even more astounding is melanin’s unique ability to absorb certain energy sources such as light and sound waves, and convert them into reusable energy.
West Africans Are Genetically Better Sprinters
James M. Tanner, the author of The Physique of the Olympic Athlete, pointed out the major racial differences among athletes in the Olympics and discovered that there is a reason so many of the top track and field competitors are of African descent. Studies revealed that the muscle composition of West Africans genetically allows them to be “the most anaerobically efficient athletes” due to the way their bodies process energy.
Kenyans Are Genetically Proven to Have High Endurance
Recent studies revealed that Kenyans have “little ammonia accumulation in their muscles from protein combustion and less lactic acid buildup. They have more of the muscle enzymes that burn fat, and their glycogen reserves are not burned as quickly, which improves endurance.”
8 Incredible Things About Black Genetics That Will Amaze You
Whites Genetically Weaker Than Blacks, Study Finds
White Americans are both genetically weaker and less diverse than their black compatriots, a Cornell University-led study finds.
Analyzing the genetic makeup of 20 Americans of European ancestry and 15 African-Americans, researchers found that the former showed much less variation among 10,000 tested genes than did the latter, which was expected.
They also found that Europeans had many more possibly harmful mutations than did African, which was a surprise.
Whites Genetically Weaker Than Blacks, Study Finds
You don't seem to have that kind of problem when the study say things about blacks.
The last 400 years tells us about reality. And that reality is not good for whites.
Some blacks helped build America 400 years ago.
Something tells me those that did are far removed from IM2 and his "gibs me dat".
Whites have been about gobs me dat since they got here.
Me when the stupid race wars heat up
We know that you've been asleep your entire life.
I'm just left hoping you don't actually have to serve any white families as part of your case load.
I'm just sad that an ignorant person such as you is allowed to teach children. You are stump stupid. I talk about whites who are racists and your stupid ass hears I hate all white people. Gaslighting does not work on me, nor does your victim mentality. No wonder our country is falling behind.
This made me laugh out loud, so thanks for that. I always appreciate a good laugh
well if yall are so advanced and superior how in the hell did blacks end up enslaved and oppressed by the evil ignorant inferior whitey like you claim !
