who came first in this world...black skinned or white skinned?

Answer 1

The current scientific belief is that 200,000years ago we all looked about the same as the !Kung in South Africa.

The basis for the assumption is a review of men's y chromosomal DNA (recent) and women's mitochondrial DNA.

We know that the rate of mutation in mitochondrial DNA is roughly stable. We know roughly what the rate of change is (about 15-20,000 years. We also know that the primary control of skin color is melanin (and related compounds).

We know that vitamin D is the only vitamin made by the human body. Vitamin D is a fat-soluble vitamin that is used by the body in the absorption of calcium.

Vitamin D may be absorbed from food by the intestines or may be produced by the skin when the skin is exposed to sunlight. In its active form, vitamin D acts as a hormone to regulate calcium absorption from the intestine and to regulate levels of calcium and phosphate in the bones.

Sunlight is important to skin production of vitamin D, and environmental conditions where sunlight exposure is limited may reduce this source of vitamin D. Lack of vitamin D production by the skin may occur if a person is confined indoors, or works indoors during the daylight hours, or lives in climates with little exposure to sunlight.

Because vitamin D is a fat-soluble vitamin, conditions that reduce digestion or absorption of fats will decrease the ability of vitamin D to be absorbed from the intestines.

When the body is deficient in vitamin D, it is unable to properly regulate calcium and phosphate levels. If the blood levels of these minerals become too low, other body hormones may stimulate release of calcium and phosphate from the bones to the bloodstream to elevate the blood levels,
and that at of osteomalacia or osteoporosis in adults. There are a number of other diseases that can occur from vitamin D deficiency : renal insufficiency, and rickets to name two.

Melanin controls sun exposure. In northern climates a lighter skin is needed in order to allow more sun to affect vitamin D production and processing. In more equatorial regions, less sunlight is needed so and the body needs protection from UV damage. So people who live in equatorial areas tend to be darker.

Scientific American has written several articles about this and National Geographic is actually looking for participants in a genetic migration study check out the links

Answer 2

I would assume that each skin trait evolved independently given the fact that Europeans went to the northern, cooler, and darker climate, and thus developed lighter skin, as they didn't need the skin protection of those that stayed around the Equator. Those primitave peoples that stayed in Afria developed darker skin to protect themselves from the sun, much like a giraffes tounge is black to prevent sunburn.

We dont know if Adam and Eve were white or not. They could have easily been black.

Answer 3

It doesn't really matter, and the people were most likely somewhere around what the middle-east looks like. The fertal cresent is where the humanoid creatures evolved from monkeys (if you believe it) went to. They came from the jungles in africa which shrunk because all of the water was stored in the polor regions on the earth (ice age). I would have to say that black and white people were made at the same time, the white people being the human's who went farther north and the black people staying more in africa.

Or if you believe in religion then just look at the common picture of the god or prophet you believe in and go with them.

Answer 4

No one knows this answer for sure! There were only two at first and they would have been the same color (what ever it was) and then, much later when the whole race was split apart and spoke different, then maybe skin color did change also! We will never know for sure the real answer to a question like this one. Until we know everything as it did happen and not just read about it.

Answer 5

The Yellow skinned.

Answer 6

DNA evidence hints that the dark came first. I would think the light came first, and then got a tan. Or maybe brown, and the browns in the north became white, while the browns near the equator turned black.

Answer 7

I believed tan skinned because God created Adam & Eve in the Garden of Eden which I believe was in the Middle East (N. Iraq), therefore granting them tan skin. Tan skin is a pausable "solution" because darker and lighten skin are similar shades to taned skin. :)

Answer 8

Scientists are going with possibly black or yellow. For a while, it was thought that we all came from Africa, which is still very possible, but now there is talk that maybe man evolved in Africa and China, so further research will tell us later.Black may be the correct answer.

Answer 9

I don't know if there is any evidence to say either way, but I would guess that is was somewhere in between very dark and white. Then, depending on where people migrated to and the climate, people then got lighter or darker through evolution.

Answer 10

Dark. The lighter skinned people came later.
