Why Did People Become White?
Live Science ^ | 9/2/2009 | Heather Whipps

Posted on 09/02/2009 12:47:20 PM PDT by SeekAndFind

Humans come in a rainbow of hues, from dark chocolate browns to nearly translucent whites.

This full kaleidoscope of skin colors was a relatively recent evolutionary development, according to biologists, occuring alongside the migration of modern humans out of Africa between 100,000 and 50,000 years ago.

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.

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.

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.

Probably ruddy - that's the literal meaning of the Hebrew 'dm

Why are middle easterners considered "white?"

Why the fudge do moronic Americans use the 19th century junk-science term "caucasian."

Why do we, alone among nations, categorize "hispanic" as a separate racial category?

Why do retards in the New York area refer to Latinos as "Spanish."

Not so fast. There is growing evidence that the Out of Africa was just one more Liberal brain fart. Modern man seems to have evolved separately in Europe, and possibly Asia as well, from Homo erectus.

Well, if you believe in evolution, then it occurs to me that the earliest humans had white skin at the very beginning simply for the reason that animals with fur tend to have light skin as there is no need for such a high melanin content.

As the earliest humans lost the need for hair that covered ones entire body, our skin gradually darkened to protect us from the sun.

I always thought it was because God took us out of the oven too soon. The next batch he burnt black. The third batch came out a beautiful tan and was just right. At least this is how my Indian anthropology professor explained it.

They needed to camouflage themselves when hunting in snow and they didn’t know how to tan hides and dye them white yet, so they simply told their bodies to do the evolution thing and turn white. There, logical explanation for everything.

The naturally darker ones bred more while the pale ones said "Ow! Ow!" because of their sunburns when they tried to.

It’s an evolution things—higher levels of melontonin protect the person from the effects of the sun. Hence, one becomes “bronzed” or “tanned” when they spend a long time in the sun.

I think because they hunted by day. Or lived in the snowy areas where they could blend in. Like good Cammo. Blacks were probably nocturnal hunters.

There is no clear definition of “race,” or which precise set of people make up one particular race. That doesn’t mean the term is per se meaningless, however. The best approach I know is to consider genetic distance: The more genes two people have in common, the smaller their genetic distance, and the more genes differ, the greater. Now you can draw a circle of a certain constant genetic distance around any given person and declare all people who fall inside this circle his “race.” This is a meaningful concept, even if there is still some arbitrariness in it, namely the value of the radius. Depending on how you choose the radius, you may consider Germans and Poles to be different races, or the same. You may even consider whites and blacks to be of the same race if you only choose the radius large enough.

So, regarding hispanics, it is not entirely stupid to consider hispanics a different race from whites because it seems pretty certain that you can choose the radius in a way that will clearly seperate them. Whether it is important, or desirable to do so, that is a different question.

Most evidence supports the first humans emerging out of Africa. As such they would have black skin.

According to some of the more benighted and ignorant creationists, the human genome can only be ‘degraded’ after the Fall of mankind. White skin is caused by mutations that render nonfunctional some of the genes that would make the skin black.

Thus according to that way of “thinking” blacks are not only the first humans, but also more in the ‘perfect’ original state of mankind - and whites have degraded from that more perfect state of humanity.

Indian anthropology?

Deep common ancestry of Indian and western-Eurasian mitochondrial DNA lineages.

http://www.ncbi.nlm.nih.gov/pubmed/10574762

Kivisild T, Bamshad MJ, Kaldma K, Metspalu M, Metspalu E, Reidla M, Laos S, Parik J, Watkins WS, Dixon ME, Papiha SS, Mastana SS, Mir MR, Ferak V, Villems R.

Department of Evolutionary Biology, Tartu University, Tartu, 51010, Estonia.

About a fifth of the human gene pool belongs largely either to Indo-European or Dravidic speaking people inhabiting the Indian peninsula. The ‘Caucasoid share’ in their gene pool is thought to be related predominantly to the Indo-European speakers. A commonly held hypothesis, albeit not the only one, suggests a massive Indo-Aryan invasion to India some 4,000 years ago [1]. Recent limited analysis of maternally inherited mitochondrial DNA (mtDNA) of Indian populations has been interpreted as supporting this concept [2] [3]. Here, this interpretation is questioned. We found an extensive deep late Pleistocene genetic link between contemporary Europeans and Indians, provided by the mtDNA haplogroup U, which encompasses roughly a fifth of mtDNA lineages of both populations. Our estimate for this split is close to the suggested time for the peopling of Asia and the first expansion of anatomically modern humans in Eurasia [4] [5] [6] [7] [8] and likely pre-dates their spread to Europe. Only a small fraction of the ‘Caucasoid-specific’ mtDNA lineages found in Indian populations can be ascribed to a relatively recent admixture.

Actually, Adam is derived from Adamah, which is the Hebrew word for dry dirt or dust. Adam was taken from Adamah. God made man from dust and to dust he shall return. I don't place any importance on the idea that ‘dm denotes that Adam had a ruddy complexion.

It strikes me that very dark pigmentation is as specialized as, or even moreso than, very light pigmentation.

The whole “Out Of Africa” thing was designed to subvert the dominant paradigm of the era in which it was first introduced, imho. It was, and is, political. The “scientific” assumptions upon which the theory was based, are sketchy, as we’re seeing now.

The ugly thing about this theory, is that it’s racist, itself. The base assumption is that the smart ones got out. What does that say, about those who remained? Just about the same thing Darwin said, come to think of it.

Jesus looks pretty white in that Last Supper painting and that Renaissance painter guy was a pretty smart dude.

Why the fudge do moronic Americans use the 19th century junk-science term "caucasian."

Because if you say Caucasoid, Europid, or Europoid it rhymes with hemorroids.

Why do we, alone among nations, categorize "hispanic" as a separate racial category?

Because they were mean and pissed off enough in the 1960's to scare the people who passed those laws - squeaky wheel gets the grease.

Why do retards in the New York area refer to Latinos as "Spanish."

Because they are from Spanish Harlem.

There!

Since the bottom of feet and palms of the hands are white, wouldn't that mean that white is the default color?

Also, I've read that black babies come out white, and turn black later.

It’s more specific than that, Adamah. It means red clay, the red clay of Israel. A ruddy complexion is reddish. So, there is some basis for the contention.

Personally, I didn’t like being called a “Son of Shem.”

Avoiding ovens you caucasoids so like is another reason.
