Why do White people have white skin?

Question

I understand that White people can be found on furtherest away from the equator, both north and south.

Then how come the Polar bear has black skin?

The Polar bear a mammal that has suited to the cold climates of the Arctic. A polar bear's nose and skin are black and the fur is translucent despite its apparent white hue. The fur is good camouflage as well as insulation. The Polar bear’s fur absorbs ultraviolet light.

byderule, the connection is that humans and polar bears are both humans. You dumb head. Lol

Polar bear and humans are both mammals, is what I was supposed to say. LAWL.

Answer 1

Just for fun

Answer 2

White people have white skins because they lack the coloring pigment that causes the skin to get dark.This coloring pigment protects the skin from the harmful rays of the sun. Asians and african have most of those pigments. Another reason is environment. The forefathers of the white people lived at a place where the surrounding temperature is below 20 degrees celcius by which their skin adapt to the temperature and where the sun does provide too much heat.

Answer 4

The least exposed you are to sunlight the lighter your skin becomes. That's why there are light or colored people. It's melanin (pigment) which causes your skin to darken to shield your skin from the sun's harmful rays.

Nature has rather designed a polar bear's dermal layer (which includes by the way the nose) to black to increase body temperature not necessarily anything to do with the sun.

Answer 5

Bzzt, wrong. European skin color is not related to distance from the equator.

Hunter-gatherer peoples who live in the arctic are usually darker than Europeans.

Europeans have 'white' skin because the diets of neolithic farmers was low in vitamin d. Hunter gatherers get all they need from the livers and kidneys of the animals they hunt.

It wasn't a big deal in reasonably sunny climates. If you get enough UV and the precursors to vitamin d your body can make it in its skin. It isn't sunny enough in northern and central Europe for olive skinned or darker people to synthesize enough to assure healthy bone growth in lean years. Even now dark skinned people should take vitamin d supplements in northern climes to insure good skeletal health.

The result of lifelong vitamin d deficiency in a population is a much higher rate of childbirth related death. Stunting the growth of the hips makes an ordinary tight squeeze perilous.

Lighter and lighter skin reduced and eliminated that problem, altering the shape of the hips slightly also helped.

Polar bear skin and light conducting fur is an adaptation for heat absorption. People can make clothes and build fires it they're cold they don't need to change color for that.

Answer 6

How can you compare the two? How many people do you see running around with fur like a polar bear growing out from their skin? You are trying to compare apples and oranges.

Answer 7

our skin has this stuff called melanin. the amount determines how dark our skin is: the more you have, the darker the skin. it also protects us from harmful UV rays that can cause skin cancer. well, our bodies also need vitamin D to absorb calcium and deposit into your bones. vitamin D depends on UV rays for production. in rich sunlight areas (i.e. the equator) the body has an abundant supply of vitamin D. however, the farther away from the equator one goes, the less direct sunlight there is. less direct sunlight=less UV rays=less vitamin D. so to compensate, humans that moved north started producing less melanin(which made the skin lighter) in order to keep receiving UV rays and vitamin D. the highest risk for vitamin D deficiency is above 50 degrees latitude (i.e. Scandinavia, Russia, Canada). that's why Scandinavians are the whitest of the white! that's also why when white people live nearer to the equator (or go to the tanning beds), they are more susceptible to skin cancer.

Answer 8

are u crazy whats the connection between polar bears and humans anyway human skin color depends upon the amount of melanin present in skin. More is the melanin more fairer is the skin

Answer 9

The skin colour comes from the amount and type of melanin in th skin.There are 2 types of melanin: the pheomelanin(red) and eumelanin(dark brown to black).However,the colour of the skin comes mostly from the gene of the father and mother.Both the amount and type are determined from 4 to 6 genes which operates under incomplete dominance.One copy will be inherited from both mother and father which comes in several alleles,resulting in variety of skin colours.

Answer 10

White people have white skin because they have much less melanin pigment in their skin. Why White-skinned people predominate in less sunny areas is a geographic, cultural and historical expedience of fate. It is definitely unrelated to polar bear skin.

Answer 11

IT's all about the pigmentation of the skin cells and your mother and father. You probrably get the colour of your skin from your parents and the skin pigmetation also has something to do with it. Try a search on pigmentation! Sure you'll find what you want.
