Scientists Find A DNA Change That Accounts For White Skin
Washington Post ^ | December 16, 2005 | Rick Weiss

Posted on 12/15/2005 10:05:07 PM PST by RWR8189

Scientists said yesterday that they have discovered a tiny genetic mutation that largely explains the first appearance of white skin in humans tens of thousands of years ago, a finding that helps solve one of biology's most enduring mysteries and illuminates one of humanity's greatest sources of strife.

The work suggests that the skin-whitening mutation occurred by chance in a single individual after the first human exodus from Africa, when all people were brown-skinned. That person's offspring apparently thrived as humans moved northward into what is now Europe, helping to give rise to the lightest of the world's races.

Leaders of the study, at Penn State University, warned against interpreting the finding as a discovery of "the race gene." Race is a vaguely defined biological, social and political concept, they noted, and skin color is only part of what race is -- and is not.

In fact, several scientists said, the new work shows just how small a biological difference is reflected by skin color. The newly found mutation involves a change of just one letter of DNA code out of the 3.1 billion letters in the human genome -- the complete instructions for making a human being.

"It's a major finding in a very sensitive area," said Stephen Oppenheimer, an expert in anthropological genetics at Oxford University, who was not involved in the work. "Almost all the differences used to differentiate populations from around the world really are skin deep."

Who's Allah? Is he any relation to Satan? No offense, I'm just curious.

This doesn't mean that either shade is superior to the other.

As a blonde, blue-eyed, light-skinned girl, I always wondered what the hell I was selected for for living on this planet.

So all the men of the world could have somebody to buy drinks for. ;-)

I think it was just a poorly worded way of saying that differentiation of humans by color is one of the sources of strife, not white skin per se.

I don't give the MSM the benefit of the doubt

Well.. Here's the way Uncle Remus tell's it:

WHY THE NEGRO IS BLACK

ONE night, while the little boy was watching Uncle Remus twisting and waxing some shoe-thread, he made what appeared to him to be a very curious discovery. He discovered that the palms of the old man’s hands were as white as his own, and the fact was such a source of wonder that he at last made it the subject of remark. The response of Uncle Remus led to the earnest recital of a piece of unwritten history that must prove interesting to ethnologists.

“Tooby sho de pa’m er my han’s w’ite, honey,” he quietly remarked, “en, w’en it come ter dat, dey wuz a time w’en all de w’ite folks ’uz black—blacker dan me, kaze I done bin yer so long dat I bin sorter bleach out.”

The little boy laughed. He thought Uncle Remus was making him the victim of one of his jokes; but the youngster was never more mistaken. The old man was serious. Nevertheless, he failed to rebuke the ill-timed mirth of the child, appearing to be altogether engrossed in his work. Mter a while, he resumed:

“Yasser. Fokes dunner w’at bin yit, let ’lone w’at gwinter be. Niggers is niggers now, but de time wuz w’en we ’uz all niggers tergedder.”

“When was that, Uncle Remus?”

“Way back yander. In dem times we ’uz all an us black; we ’uz all niggers tergedder, en ’cordin’ ter all de ’counts w’at I years fokes ’uz gittin’ ’long ’bout ez well in dem days ez dey is now. But atter ’w’ile de news come dat dere wuz a pon’ er water some’rs in de naberhood, w’ich ef dey’d git inter dey’d be wash off nice en w’ite, en den one un urn, he fine de place en make er splange inter de pon’, en come out w’ite ez a town gal. En den, bless grashus! w’en de fokes seed it, dey make a break fer de pon’, en dem w’at wuz de soopless, dey got in fus’ en dey come out w’ite; en dem w’at wuz de nex’ soopless, dey got in nex’, en dey come out merlatters; en dey wuz sech a crowd un um dat dey mighty nigh use de water up, w’ich w’en dem yuthers come long, de morest dey could do wuz ter paddle about wid der foots en dabble in it wid der han’s. Dem wuz de niggers, en down ter dis day dey ain’t no w’ite ’bout a nigger ’ceppin de pa’ms er der han’s en de soles er der foot.”

The little boy seemed to be very much interested in this new account of the origin of races, and he made some further inquiries, which elicited from Uncle Remus the following additional particulars:

“De Injun en de Chinee got ter be ’counted ’long er de merlatter. I ain’t seed no Chinee dat I knows un, but dey tells me dey er sorter ’twix’ a brown en a brindle. Dey er all merlatters.”

“But mamma says the Chinese have straight hair,” the little boy suggested.

“Co’se, honey,” the old man unhesitatingly responded, “dem w’at git ter de pon’ time nuff fer ter git der head in de water, de water hit onkink der ha’r. Hit bleedzd ter be dat away.”

Then why don't we see a gradual darkening again as we head north?

"Darwinist 'evolution' also claims that life came from non-life,"

"Actually, the theory of common descent says exactly the opposite, that all extant populations evolved from earlier populations."

This is what happens when ignorance tries to lay an ambush with bait and switch bombs. The theory of common descent itself must begin out of nothing, (or from the Big Bang, which itself was created out of nothing according to Darwinist theology). You claim nothing existed before the "Big Bang", but that the "big Bang" created life and everything else; (in other words, 'nothing' created the "Big Bang", which in turn created everything else. So silly.

Darwinists claim that all of creation came out of nothing, the universe emerging for the first time from the, ahem, "big bang". Ask any good Darwinist what existed before their "big bang", and the answer is 'nothing'. So we have 'nothing' causing a "big bang", which caused life in all of its forms, and the entire, ever-expanding universe as well. So once again I will say: "Darwinists claim that life came from non-life, and that everything proceeded from nothing". Which is, of course, rubbish. Old, rotting rubbish at that.

"Creationists, on the other hand, actively promote the idea that life came from non-life, witness Genesis 2:7"

More nonsense from the uninformed. Genesis clearly reveals that life came from God, "Who Am". God indeed created everything out of nothing, for before His creation there was nothing but Himself. When God fashioned man's body from the clay of the earth, man was still made from 'nothing', because God then "breathed into his (man's) nostrils the breath of life", which is the spirit and soul, (the image and likeness of God).

No, it begins with a population of uniform imperfectly replicating organisms. Where those uniform imperfectly replicating organisms ultimately originated is beyond the scope of common descent. Stop lying about evolution.

So once again I will say: "Darwinists claim that life came from non-life, and that everything proceeded from nothing". Which is, of course, rubbish. Old, rotting rubbish at that.

You're right. It is rubbish to say that "Darwinists claim that life came from non-life, and that everything proceeded from nothing." Why do you repeat claims about "Darwinists" that you know are a lie? Why do you attribute claims to them that you know that they do not make?

Bet asians (Yellow)

What Asians? You mean IRanis or Indians or Russians (that big chunk of Mother Russia that's in Asia?) who are Indo-Europeans /Aryans or Dravidians or the Jews, ARabs etc. (who are Semitic, a branch of the Caucasians). he South East Asians are more brown than yellow in color and even the far easterners -- the mongoloid race is far more closely related to the caucasaian race than either is to the African races.

No, the theory of common descent doesn't specify where the first life came from. Some scientists believe that it arose through natural procecesses affecting complex organic molecules, my own personal belief is that it was created by the Almighty. But that's not a question that evolution even pretends to be able to answer.

(or from the Big Bang, which itself was created out of nothing according to Darwinist theology)

Canard. The Theory of Evolution has nothing whatsoever to do with the Big Bang, except for the fact that both are scientific theories. They're not related in any way, except in your mind. And I'm not sure why you believe that God could not have been responsible for the Big Bang -- to me, it is the greatest evidence for His existence yet known.

"Darwinists claim that life came from non-life, and that everything proceeded from nothing". Which is, of course, rubbish.

Yes it is rubbish, because I'm a "Darwinist" and I do not believe that -- you're tilting at strawmen.

To build on your theory, which is one I am also familiar with, if you buy into natural selection at all, it would also make sense that in the lighter, more colorless climate of the north, that a camouflage effect would be useful among a nomadic people, in much the same way as it benefits animals. It might not play as much of a role, but worth consideration nonetheless.

No matter; I've always believed that blackness or whiteness, as a genetic component, was environmentally functional. As an aesthetic component, I think our creative God just loves variety. Imagine if flowers and birds were only one color.

Wow, so they've identified the white gene as responsible for all of the strife in the world. What racist rubbish.

Racist Idiots!

You are kidding, right? Don't you know all people are created equal, with exactly the same attributes. No group has any genetic attributes that benefit them over another.

Just kidding. Two things genetically different primarily responsible for "White Men Can't Jump" syndrome. Routing of muscles in "upper thigh" (over the butt - thus "Baby's got back" is an accurate observation) plus the ratio of fast twitch to slow twitch muscle.

Look at long distance running, where these attributes do not dominate the equation.

But these facts do not stand in the way of the racist NBA not employing more white men to better represent the general population.

'Caucasian' is a geographical term, not a racial term.

D'uh, Caucasian is a racial term. You have three main races: Caucasians, Orientals and Negroids. The Caucasians are separated from the other two by the Sahara, the Tibetan plateau, the Gobi and Siberia.
