You are so stupid cause white people are a GENETIC MUTATION. So how are you gonna be racist to any other skin color when you wasn't even gonna exist? Here's why white people are mutations.
The consensus among scientists has always been that lower levels of vitamin D at higher latitudes — where the sun is less intense — caused the lightening effect when modern humans, who began darker-skinned, first migrated north.
Vitamin D plays an important role in bone growth and the body's natural protection against certain diseases, and the inability to absorb enough in areas of less-powerful sunlight would have decreased life expectancies in our African ancestors. The further north they trekked, the more vitamin D they needed and the lighter they got over the generations, due to natural selection.
This explanation accounts for the world's gradients of skin color traveling south to north, the prevalence of vitamin D deficiency among African immigrants to higher latitudes, as well as the relatively darker skin of Canada's Inuit peoples, who have good levels of vitamin D despite living in the Arctic, due to their diet rich in oily fish.
But other factors might be at work, a new study suggests. From the varying effects of frostbite to the sexual preferences of early men, a host of theories have been reviewed.
Scientists have long known that Africa is the cradle of human civilization. There, our ancestors shed most of their body hair around 2 million years ago, and their dark skin protected them from skin cancer and other harmful effects of UV radiation. When humans began leaving Africa 20,000 to 50,000 years ago, a skin-whitening mutation appeared randomly in a sole individual, according to a 2005 Penn State. That mutation proved advantageous as humans moved into Europe. Why? Because it allowed the migrants increased access to vitamin D, which is crucial to absorbing calcium and keeping bones strong.
The Penn State researchers' findings on the skin-whitening gene
show that skin color accounts for a minuscule biological difference between humans.
When the research was first published, scientists and sociologists feared that the identification of this skin-whitening mutation would lead people to argue that whites, Blacks, and others are somehow inherently different. Keith Cheng, the scientist who led the team of Penn State researchers, wants the public to know that's not so. He told the Post, "I think human beings are extremely insecure and look to visual cues of sameness to feel better, and people will do bad things to people who look different."
His statement captures what racial prejudice is in a nutshell. Truth be told, people may look different, but there's virtually no difference in our genetic makeup. Skin color really is just skin deep.
Skin lightening could also have been accelerated by something as simple as genetic drift, making it “easier” for a pale skin mutations to succeed in northern latitudes.
Though other elements may have come into play and need to be examined further, vitamin D remains the most likely explanation, Juzeniene stressed, especially given its role in overall health.
“If we assume that vitamin D does not play any role in the development of human skin color, neither white nor dark, many people in the world would suffer from vitamin D deficiency,” she said.
THANK YOU allison FOR THIS SEASON!!!! I enjoyed watching every bit of it and the drama by brea was IMMACULATE the looks by nichole was POWERFUL I wish the fans had a all rookie season but I love EVERYONE so much <3 SEASON 4 HERE I COME
