All blacks can be traced back to Africa. What is the origin of the white race? We know they lived in the Caucasus Mountains. Where did they come from before that?

The skin shade of the locals of a given area who have been living there for millenia relies upon the measure of daylight in that district. The procedure works through common choice. Bright light, the color melanin and snow (or ice) are the significant catchphrases.

Darker skin is naturally chosen in situations, for example, tropical districts where there is a considerable measure of light and by expansion a great deal of bright radiation in light of the fact that the shade melanin ensures against all that bright light. Because of this security gave by the shade melanin, individuals with darker skin survive marginally more and deliver somewhat more offpsring than individuals with lighter skin in each age in those situations. Subsequently, after the entry of a couple of millenia and numerous ages, every one of the locals of such areas are dim cleaned regardless of whether a few or all were light-cleaned toward the start.

The inverse occurs in less radiant locales which are both far from the Equator and which don't have heaps of snow and ice. In such locales, lighter skin is chosen. Regardless of whether the underlying occupants had dull skin by and large, those of them who have had marginally lighter skin shading have been chosen in each age. Since these lighter-cleaned individuals have less melanin in their skin, a greater amount of the bright light required by their body in direct sums is consumed by their skin. Along these lines, in these moderately sun-and bright light-denied locales, the lighter-cleaned individuals can live more and create all the more posterity. Along these lines we get the inverse of the previously mentioned outcome: After the entry of a couple of millenia and numerous ages, every one of the locals of such districts are light-cleaned regardless of whether a few or all were dull cleaned toward the start.

Tropical locales are not by any means the only places with bunches of daylight. Snow and ice reflect daylight and may cause as much light to be gotten by the human body as in tropical areas. That is the reason Eskimos live so up north yet regularly have such dull skin.

Now, recollect that the last Ice Age finished 11,700 years back, that is, around 9,700 BC. At that point started the present "holocene" in which the vast majority of the northern parts of the world are never again shrouded in ice and snow and are significantly more generally inhabitable. This clarifies why, as you may have perused on the news, northern Europeans turned out to be so light in skin shading after the last Ice Age.

The news said that toward the finish of the last Ice Age, Europeans had dim skin and after that their skin ended up white because of the relocation of agriculturalists from the Close East, that is, the Prolific Sickle in exhibit day Palestine, western Syria, southern Turkey and southeastern Turkey. In any case, the genuine explanation behind the reasonable skin shade of numerous Europeans in the present day mustn't be that Close Eastern movement that happened millenia back however should be the procedure of common choice that I've quite recently attempted to clarify. Those lighter-cleaned Close Eastern transients were presumably just as light-cleaned as present day Close Easterners from Syria and southern Turkey are, and were not as light-cleaned the same number of Europeans today seem to be.

As a matter of fact, the considerably less frigid, significantly less cold and hence substantially less sunlit nature of Holocene Europe caused the procedure by which the lightest-cleaned were chosen in more northerly regions of it. A similar thing occurred in other northern zones of the world, which are far from the Equator. The main special case is, as I specified over, the still cold and frigid polar areas whose Eskimo tenants have stayed dull cleaned as a result of all that daylight which the ice and snow reflect, which normally chooses the darker-cleaned.
