Question

white people are white because they dont need protection from the sun, why have oriental people got narrow eyes, and why are they yellow? Serious question, no twatty answers please.

thequiet...... you know the answer then?? you bellend

Answer 1

To protect their eyes from the wind. And Asians are varied in color: from very pale to dark brown. It all depends on where they reside.

We all evolve in ways that we can adapt to our environment. Black: broad noses to breathe in hot air and dark skin to protect from sun

White: thin noses to breathe in cold air and lighter skin from lack of sun

Asian: no eyelids to protect their eyes from the wind.

Answer 2

Oriental people have the slightly different eyes because centuries ago that area of the world suffered from sand storms and they needed eyes that would keep out the grains of sand. It's not like that any more but it takes many years for peoples appearance to change. I must take issue with you however on the issue of calling them yellow. The simple truth is they (Chinese, Japanese etc) are as white as the Europeans.

Answer 3

It appears that they are all different because of what environment they lived in. When peolpe who first appeared in Africa, grew in numbers, and began to expand to the other continents. Africans moved to other parts of the rest of the world and it exposed them to a great variety of environments: from hot and humid or hot and dry environments (to which they were already accustomed) to temperate and cold ones, including the coldest ones of the world, as in Siberia. We can go through some of the steps that this entailed.
Exposure to a new environment inevitably causes an adaptation to it. In the 50,000-100,000 years since the African diaspora, there has been an opportunity for substantial adaptation, both cultural and biological. We can see traces of the latter in skin color and in size and shape of the nose, eyes, head, and body. One can say that each ethnic group has been genetically engineered under the influence of the environments where it settled. Black skin color protects those who live near the equator from burning under the sun's ultraviolet radiation, which can also lead to deadly skin cancers. The dairy-poor diet of European farmers, based almost entirely on cereals that lack ready-made vitamin D, might have left them vulnerable to rickets (our milk still has to be enriched with this vitamin). But they were able to survive at the higher latitudes to which they migrated from the Middle East because the essential vitamin can be produced, with the aid of sunlight, from precursor molecules found in cereals. For this Europeans have developed the whiteness of their skin, which the sun's ultraviolet radiation can penetrate to transform these precursors into vitamin D. It is not without reason that Europeans have, on average, whiter skin the further north they are born.
The size and shape of the body are adapted to temperature and humidity. In hot and humid climates, like tropical forests, it is advantageous to be short since there is greater surface area for the evaporation of sweat compared to the body's volume. A smaller body also uses less energy and produces less heat. Frizzy hair allows sweat to remain on the scalp longer and results in greater cooling. With these adaptations, the risk of overheating in tropical climates is diminished. Populations living in tropical forests generally are short, Pygmies being the extreme example. The face and body of the Mongols, on the other hand, result from adaptations to the bitter cold of Siberia. The body, and particularly the head, tends to be round, increasing body volume. The evaporative surface area of the skin is thus reduced relative to body volume, and less heat is lost. The nose is small and less likely to freeze, and the nostrils are narrow, warming the air before it reaches the lungs. Eyes are protected from the cold Siberian air by fatty folds of skin.

Answer 4

I've never seen a "yellow" oriental. I have seen orientals with a yellow undertone to their brown skin. Orientals are from light skinned to dark. Someone here said it. It depends on where they are from. Black, white, oriental, indian are all the colors that they are because god made the colors.No explanation is necessary.

Answer 5

The ignorance of people will never cease to surprise me. Two Italian friends of mine got skin cancer. Italians' skin is like other Europeans' one, who told you that our skin tone protects us from cancer?

Answer 6

maybe balck people need a lot of protection because they originate in Africa and white people dont need barely any protection because they are from up north in Europe and oriental people probably need some protection in between. and that is probably the same deal with south american people

Answer 7

Wind protection sounds right to me. As to skin color, that's a dominant/recessive gene game. There are in fact 16 possible variations in skin color, only a few of which we actually recognize.

Answer 8

**** and proud.

Dont worry about twatty answers when you have asked such a twatty question
