Or yellow people for that matter. Black people have black kids. They then have black kids of their own. How did white people in fact come from black people? Could you take a population of black people today, and run a eugenics program on them, and make white people using nothing other than selective breeding? Sure, there might be mutation every once in a while, one in every billion black couples might pop out a white kid just randomly, but it would be a drop in the ocean. What kind of factors could have selected in favor of a whole race of millions of white people emerging? Discuss.
Didn't you know? Blacks and Asians and all non-whites share ancestry with monkeys. White people were created from scratch by God.
Chemicals in our skin that react to the enviroment. Over long periods of time. Correction: Ah screw it.
Why do white people exist? Because it's more fun than not existing. (And you thought you were going to get a long, detailed, scientific explanation... )
Thousands of generations of living in low sunlight would to do it. High skin melanin content becomes more and more useless over time, wait a few hundred thousand years and bam! white dudes
In a lower-sunlight environment, you need less melanin in order to get the same UV rays for proper Vitamin D production. Lifespans of black people in northern Europe were likely right around childbearing age until they started giving birth to white people who more consistently survived to childbearing age. At least that's what I remember from High school biology.
This doesn't explain the, you know, total lack of any large scale young-death-problem or widespread vitamin D deficiency disorders among the present day black minority populations of Canada, Scandanavia, et al.
i don't suppose the centuries of improvement in diet and importing food have any bearing on it at all
Blacks have been living in northern latitudes for 3 - 4 centuries, first as slaves, later as migrants. For most of this time, all the fancy vitamin supplements we have today did not exist. E.g. in the mid-1800s if you were a slave in America the place to escape to was Canada. And thousands of slaves did escape thence via the underground railroad. But you don't hear of them getting rickets or their kids getting rickets... IOW maybe vitamin D wasn't the real culprit for the emergence of whitey.
Of course, scientific and technological advancement has negated the need for natural human evolution. How do white people survive in the tropics? Sunscreen, protective clothing, shelter, etc. How do blacks retain Vitamin D in colder climates? Food pumped with nutrients, multivitamin tablets, etc. Or if you mugs wanna get technical with it: "Humans have pigment cells, which contain pigment granules called melanosomes. In people of European descent, the melanosomes are fewer, smaller, and lighter than those from people of African ancestry, while the melanosomes of East Asians show intermediate properties.[38] According to a 2006 study by 10 scientists, lighter pigmentation observed in Europeans and East Asians is due to independent genetic mutations in at least three loci. They concluded that light pigmentation in Europeans is at least partially due to the effects of positive directional and/or sexual selection. According to the study, the results also strongly suggest that Europeans and East Asians have evolved light skin independently and via distinct genetic mechanisms.[39] People with a light-skin-causing mutation at the gene SLC24A5 apparently proliferated as humans moved northward into what is now Europe, where there is less sunlight available; explaining between 25 and 38% of the European-African difference in skin melanin index.[40][41] The advantage of light skin in higher latitudes is that it does not block sunlight as effectively, leading to increased production of vitamin D3, necessary for calcium absorption and bone growth[42]. "
rickets was endemic across the northern US and europe until the mid 1920's, the worst effected being blacks and redheads. anyone heading towards newfoundland would've lucked out though, cod's a decent source of vitamin D and cod liver oil was taken in the region prior to its use to combat rickets. try again.
i'm being a bit bitchy towards slough here aren't i? i think thats my minds way of telling me to fuck off to bed.
Wasn't there a super volcanic eruption around 75,000 to 80,000 years ago that pared the human population down to about 5,000 individuals? That might account for the change. A supervolcanic eruption would have blocked out most of the sun for years.
Na it's normal to be like that with him. He is a waste of skin after all. Now i'm off to bed before the sun comes up.
