Question

Other Than Temperature, What Other Factors Can Influence The Skin Colour Of A Race???

Answer 1

Amount of sunlight (Ultraviolet light)

Windiness

Barometric pressure (Moisture/dryness of the air)

Cross-mating (Hybrid vigor/Genetic mix)...

Answer 2

Besides temperature, I would say society. What the people in a community value in beauty (lighter or darker skin) would become more prevalent.

Answer 3

its not temperature, its the intencity of of light rays, escimoes have quite dark skin, because it can be very sunny. but it is cold.

other than that, nothing can permenently alter the skin colour... you could get a tan... but that is not permenant.

people are black because evolution has made it that way, coz black people dont sunbnurn.

Answer 4

Diet can affect skin colour.  The pigment carotene found in carrots can make a person look orange if eaten in large enough quantities.  Plenty of red meat and foods high in iron will increase iron level in the blood, the more haemoglobin the more red the blood is.  If your white you'll end up with rosie cheeks!  Liver and gall bladder problems will mean you will retain bile in your blood stream which will be excreted through the skin pores given the skin a yellow tinge like jaundice.  Melanin is the pigmentation that makes skin tan when exposed to sunlight and it's high concentration in black people protect their skin from ultra violet light damage. Certain drugs can sometimes discolour the skin when they are excreted through the skin pores, can't remember what drugs.

Answer 5

If two people from different race-groups have a baby.:)

Answer 6

fake tan influences the skin colour of the Essex race

;)

Answer 7

Did anyone mention the obvious?  Genetics.

Answer 8

Dude, the only thing that influences the skin colour is the melanin in your body. Albinos have non!

Answer 9

skincolour depeneds on chemicals in our genes - the melanin. Dark people have more melanin cells than lighter people.

Factors affecting these cells would be artificial creams that would inhibit these cells from reproduction.

Answer 10

Skin tone depends on several factors.  the original reason for the skin tones in the world is exposure to sun light.  In areas of europe where sun light is limited, the skin is naturally lighter, to allow more sunlight to be absorbed so that the skin can make vitamin D.  Darker skin tones, are usually found in areas of the world where exposure to sunlight is more common in everyday living. Darker skin tones, act the opposite way, in repealing sunlight and ultrviolet rays because of course sunlight is much more common.  Diet can also affect skin tone and ingestion of vitamin D can reduce the bodies need to absorb sunlight. and of course genetics, which is why many native american peoples have a considerable dark skin tone despite living in northern climates.

Answer 11

interbreeding,and some blacks will burn in the sun ,but all white do

Answer 12

I would think diet could influence skin color. For example, people who drink lots of carrot juice get what called the "carotene sheen." I have no science to back up this idea, but it seems reasonable that different diets would produce varying skin qualities.

George, I would ask some black folks if they don't sunburn. I politely disagree with you on that claim.

Answer 13

Outside influences have only temporary effects on skin tone (like tan). Your parents skin color is the overriding factor.

Answer 14

Skin color was an evolutionary adaption to the exposure to light, not temperature.  I agree about black people sunburning.  I used to work for an African American in his 60's that would laugh at all the Anglo-Saxons burning to a crisp in the summer in Colorado.  He went on a vacation in the Caribbean down towards the equator.  He thought he had a skin disease because he started peeling.  So I got to laugh at him.  (I am one of those people who have almost no pigmentation, don't tan much just burn.  I love sunblock.)

Answer 15

Eskimos still have a fairly dark skin in spite of living about a far North as you can get. They consume large amounts of vitamin D from their diet, so a light skin colour has not been necessary.

Skin colour is caused by exposure to ultraviolet light, not heat.  It is most closely related to winter UV levels.

Some people that inhabit tropical jungles have a lighter skin tone than the people who live in the open areas, as the near constant shade will cut down their UV exposure.
