Question

How come Northeast Asians don't have bright colored hair even if they have the same climate as europe?

I dont get it.

People near the equator have more melanin, hence black hair and dark skin.

Europeans are far north and since there are no sunlight they evoved light skin and bright hair.

But Northeast asians have a similiar climate to europe...
Why then did they not evolve bright colored hair?

Answer 1

The light colored hair of Northern Europeans is the result of what is called founder effect. The population that first settled in that area happened to have the genes for light colored hair and eyes. Because they suffered no ill-effects from these traits (as they might have in the tropics, due to increased chance of UV damage), light hair and eyes persisted and spread in the population. There doesn't seem to be any advantage to having light hair in northern climates, so we can't really say that it evolved as a result of living in that region. Northeast Asians do not tend to have light hair merely because their original ancestral population did not have the genes for light hair.

Answer 2

Its not just the hair, its the skin and color of eyes as well as the fine features of nose, lips , and the texture of the hair. Asians and Africans all have different texture of hair. Any theory on this has to take these other factors into account. Note that northern asians do have fair skin, sometimes whiter than whites. Very good question that I cant answer!

Answer 3

When I was much younger, I wondered the same thing. Africans were dark and generally skinny to cope with heat and sun. Northern Europeans are light skinned and heavier to cope with colder and low sunlight. Northeastern Asians (orientals) have dark hair which seems to protect them from sun and they have features that protect they from cold such as the extra fold of fat on their eyes. I asked myself, where is there cold and sun. The answer is the Himalaya. Since then, I discovered that Orientals originated in the mountains of Tibet based on language studies and this seemed to confirm my theory. Also the Himalaya Mountains may have kept a population isolated for thousands of years during the last period of glaciation making evolution of the separate race possible. Due to the extreme nature of that environment, the people there developed a level of technology and culture that made them extremely capable of conquering environments from South America, the Artic, most of Asia, Japan, to Madagascar. It is just my pet theory.

Answer 4

This is a very good question!

Mutations are arbitrary...

One set of circumstances in one age, may trigger an entirely different random result, and if the mutation is successful, before long, an entire population begins to look a certain way...

A half of a million years later, a similar environment may trigger a different mutation, which becomes successful, and the subsequent breeding, influences that population with entirely different results...

When it comes to evolution, it's unpredictable...Flip a coin!

Answer 5

nicely, women human beings like staying modern and renowned and wearing varieties that are stylish. i love wearing my hair immediately. it truly is extra eye-catching, seems neater, you will locate the well-being of its subject that way, frames the face nicely. I recommend i could record countless rationalization why I like it straightened. even if it basically is an greater look to me. i do not groom myself to win the approval of the race police, individuals, or to teach something. i'm no longer someone to be managed, manipulated, shamed for being me and liking what i love. i do not owe human beings something. There are diverse issues predicted of black adult adult males because they're adult adult males. they do no longer ought to look staggering. women human beings will date unimaginably gruesome adult adult males in the journey that they are respectable earners. yet those days, they're fortunately relationship hideous bums too, so women human beings basically truly have very low criteria for adult adult males mainly in the present day, from my observations. it truly is basically adult adult males get a pass in some parts basically as women human beings do. If i wanted to artwork a low factor job all my existence, and no individual could surely care. As a lady, i do not could prevail occupation-sensible, if i do not opt for to. adult adult males do not have an similar luxurious. they're only by how nicely they artwork themselves as a lot because the proper. diverse criteria.

Answer 6

I would say because they evolved from two already different subsets of humans, and these traits had no true reason to change up until now

Answer 7

You have taken it upside down. Because you believe in the evolution. People with more melanin could go south where life is easier, those with less melanin could not - you have heard about skin cancer. But those with more melanin can go also northwards. The only way to change colour of hair, skin, eyes is to mix with other race: there is no proof of any alterations by other means, especially not by evolution.

Answer 8

A couple of months ago I checked and saw that Japanese teenagers have hairs of all sorts of colors. Red, blue, white, yellow, green, combinations, rainbow...

Answer 9

It's all in the genes! So ...genetics is your answer.
