As a geneticist, let me tell you something that applies to all humans. 1000’s of years ago, all humans were black. All. Through migration are genes didn’t alter to become white and black. The genes are the same. The difference is how those genes are expressed.

White people express less melanin, they express less mitochondrion in their muscle cells. But the genes are the same. Phenotypically we look different, but our genotypes are exactly the same.

There is a gene called SLC24A5 that is to do with skin pigmentation, it is found in Africans, as well as the palest Europeans. There are two other variants HERC2 and OCA2, that result in light skin, hair and eyes, these variants also arose in Africa. In fact these variants

arise more than a million years ago in Africa and spread to Europeans and Asians. So the genes that cause the light skin in Europe, did in fact arise from Africa. In fact is is the expression of something called eumelanin , which is the pigment responsible for black and brown

skin, hair and eyes. When eumelanin has a knockdown in expression, yellow and red tones are lost, resulting in a lightening of colour of skin, hair and eyes.

So I added that this is a knockdown of those tones, not a knockout of the gene, if it was a knockout, Europeans would be gray.

So to put in perspective, all colors have all the same genes, Africans have genes for light skin, hair and eyes as well as genes for black, brown skin, hair and eyes. These genes are both ancient. We just express them differently, resulting in our phenotype. But we are the same.

But if you want it spelling out really clearly, us Europeans are the mutants of the originals.

*our genes. DAMN AUTOWRECK

And don’t get me started on GMO’s.

Just DO NOT EAT THEM. ☠️☠️☠️☠️☠️☠️🚫🚫🚫🚫
