When genus homo emerged in Africa, their original color was black. The melanin in their skin acted as protection against the high level of ultraviolet radiation in African equatorial regions. They later spread to almost every corner of the globe and developed into various forms of the genus homo.
As they moved away from tropical sunshine, the advantage of a dark skin diminished, and another factor came into play. One of the essential vitamins is vitamin D. Most vitamins must be in food. D is an exception; humans can make it in the skin if and only if they are exposed to good sunlight. It became an evolutionary advantage to lower the amount of melanin in the skin, and the nearer the poles, the more important to do so. The further from the equator, the lighter the skin.

This is not just some wild theory; a classic confirmation occurred in UK a few decades ago. A number of children in northern England were found to have rickets. This is a disease which makes children grow up bow-legged. It is a well known symptom of vitamin D deficiency. Rickets was once common in northern England, especially in poorer families. It had quickly been eliminated when manufacturers of flour were compelled to enrich it with vitamin D.

It had now reappeared suddenly, but only in the children of immigrants from India/Pakistan. These families mostly ate rice; when they did eat bread it was made from chapati flour, imported from India, and not enriched. When enrichment was made compulsory for imported flours, the rickets quickly stopped. Indian children still have dark skins, and northern England still has little sunshine, but vitamin D did the trick.

As to the disparity in numbers between blacks and whites, truly coal-black people are found in tropical regions that are open to the sun, not heavily forested areas, not 'jungle'. The proportion of earth's habitat meeting these criteria is remarkably small.

Furthermore, the introduction of the gene for pale skin and red hair has been credited to the Ice age Neanderthals who first populated the northern zones of Eurasia. Without this adaptation it would have been difficult for modern humans to thrive in the northern reaches of our planet. After the most recent Ice Age ended, the limited sun light in the region continued to favor the survival of modern humans with this genetic anomaly of light skin color.

Why does a black man have a larger penis than a white man?

I'm not aware of any occation that required that both white men and black men to whip it out and measure. Men are too obsessed with penis size. Inch here quarter inch there whatever.

Why are Australopithecus Homo habilis and Homo erectus are different from Homo sapiens?

. Australopithecus, Homo habilis and Homo erectus are different from Homo sapiens because the Homo sapiens have a larger brain mass and larger skull structure. The modern human today is related to the early homo sapiens but back then they where a lot shorter and more robust than we are today. And th (MORE)

Why did Homo erectus Began to migrate to Africa?

They didnt migrate to Africa. They started out in Africa and migrated to everywhere else in the world. If you why did they begin to migrate out of Africa then it might be because they slowly began to move from place to place for more food or better climate.

If homo erectus were the first people on earth then where does Adam and Eve come from?

\nFrom the imagination of a people who had no access to science.\nThey are metaphorical symbols for the IDEA of human origin.\n. \nIn point of fact, Genesis can be seen to be an allegory of the true origins.\nFirst light, then stars and planets, then the earth, then the creatures of the sea then th (MORE)

How did homo sapien come to north America?

Honestly, no one knows. There are several competing theories, and it is possible that each is correct to some degree. We suspect that about 30,000 years ago, groups crossed Beringia (the land bridge that existed across the Bering Straits. They followed herds possibly, down through present day Canad (MORE)

How did homo sapiens differ from homo erectus?

Homo erectus are different from Homo sapiens in many ways. First, Homo erectus has a thick skull and a forward sloped forehead .In comparison, Homo sapiens have thinner skulls and their heads don't slope forwards. Homo sapiens have advanced verbal and written language however, Homo erectus does comm (MORE)

Where did homo sapiens come from?

The current best theory of the origins of modern man point to western Africa as the place where first animals that can be called Homo Sapiens appeared. The earliest fossil that has been classified as Sapiens was found in the valley of the Omo river in south-western Ethiopia and are dated at arou (MORE)

Why is man known as Homo sapien?

\nThe word "homo sapien" in greek means "wise man" or "thinking man". This was to make the mental capacity different to an earlier human species, such as, say, "homo erectus" or "the walking man". These creatures could walk and act like us, but weren't as smart or social. So modern humans get the ho (MORE)

Where did homo sapiens evolve?

Why is Homo in Homo sapiens capitalized?

This is the convention in the system of binomial nomenclature (two-part names) developed by Linnaeus in the 18th century.

Africa is the original birthplace of Homo sapiens. It has been proved that the human race originated in Africa. A good short reference about the subject is "The Journey of Man" by Spencer Wells.

In what sense is a man Homo Viator?

Well, a 'homo viator' means 'pilgrim man', and in some sense we are all traveling and journeying to different places throughout our lives. A man is never ever satisfied.. so he journey's not in the sense he go through other places or go to the deepest ranges. But to the extent of looking for his (MORE)

What is the difference between homo sapiens and homo erectus and homo habilis?

Homo habilis was the earliest of these three hominids and perhaps the most ape-like of them, though it did not stop habilis from being the first known hominid to make and use stone tools. Homo erectus was their later descendant. Erectus was smarter, though their brains were still a little smaller th (MORE)

Homo sapiens are just barely taller, 1.5 to 1.8 meters on average, while Homo erectus is 1.778 meters. The forehead rises sharply on the Homo sapiens, and eyebrow ridges are very small or more usually absent, and the chin is prominent, unlike the Homo erectus.

The oldest examples of Homo Sapiens is from the Omo remains, presumably dating back to 195,000 in Ethiopia. It was another 60,000 years until Homo Sapiens remains become prolific and visible in other parts of the world. This supports the "out of Africa" theory that Homo Sapiens, like many of the oth (MORE)

I believe that you're talking about the early humans... because we're Homo sapiens. I don't think they did, but they may have had some sort of body language or starting to make formations of the mouth then.

No. However many people seem to, wrongly, think so. I actually spoke to a woman just the other day who swore that the pill did not work with black guys!

Did homo sapiens evolve from neanderthals?

No, although both evolved from the common ancestor Homo Heidelbergenis. Homo Sapiens did however interbreed with Neanderthal, consequentially, Caucasian and some Asian races of Homo Sapiens today have 2% Neanderthal DNA, making us a somewhat 'hybrid' species.

The problem is that some of the erectus finds are actually ape andothers clearly sapien and these two have sometimes been mixed orblended giving the appearance of them being one creature (we sawthis in Java Man and Peking Man). The evidence could just as wellindicate both species living in close pro (MORE)
