Why do black people have different hair than white people?
970275
Different hair types evolved basically to protect the brain in different climate extremes.\nWhite people evolved in cool climates, and so...for the most part...have limp hair that lays down on the head.  (i.e.:  providing warmth, like a blanket)\nBlack people evolved in tropical climates, and their tight, curly hair both provides shade (keeping direct sunlight from beating down on the top of the head) but at the same time allowing wind to blow through, which provides a cooling effect.

By definition, there cannot be a "smarter race" amongs humans, and that is because races DO NOT EXIST in the human species. The differences in the genetic makeup of individuals amongst the human species is just SO small that people cannot be truly classified under "Races", like for example with dogs. It is said that there is a chance that you are genetically more similar to a black person than you might be to another white person. And it is also thought that most "Racial" traits are but adaptation to different environments. Thus, it could be inferred that if Black people stayed on a cold weather, without much son for long enough time, their descendants would eventually be whiter with each passing generation.

Black people are generally taller, with longer legs, a leaner body frame, and larger nostrils for breathing in more air.  These are environmental adaptations from eons of living in Africa.  A lot of those features are still there today.  These features allow them to run faster than Whites.  Is this true for all? NO. Just a generalization of supported scientific facts.\n\nAs forthe three point shots, well, that's just opinion.

A black person's teeth are no more naturally white than a white person's teeth.  And they have the same problems with their teeth as well.

Yes it is. You'd be surprised at the recessive genes  a lot of black  folks have, so they may just look like the average person of African decent but they may have a lot of other genes from other groups dormant in their genetic code. So it is entirely possible that the child could have straight hair.

Don't know what you are talking about but , different colors look different on different people, whether man or woman everyone has  a certain color that looks good with their skin tone or eye color.  You just have to experiment

Hair color, eye color, and also skin color are determined by special proteins called pigments.  The pigments in your hair, eyes, and skin are encoded in your genes, which is was these traits are said to be genetic.  All molecules absorb some wavelengths of light and reflect others.  Pigments are typically complex molecules that reflect certain wavelengths in the visible spectrum and absorb others.  Different people have different color pigments because there are minor changes in the DNA sequences that code for the pigments which result in minor changes in the molecules themselves, which in turn change the wavelenghts of light that are reflected and absorbed.  If someone has blue eyes, it is because the pigments in their eyes reflect a lot of wavelenghts of blue light, and absorb most other colors.

blacks and whites have the same abilities they have just different color skin but maybe because they come from a different country

We all have different amounts of melanin in our skin. If we have less, our skin is lighter. If we have more, our skin is darker.

blacks are beautiful people nice color, there are people that get tans and fuller lips to look simular to blks. but just like any other race some can act very stupid at times.

heritage, genetics, life.  Any answer could give you many scientific ideas as to why your hair gets darker over time, even blondes sometmes have that happen.  It's just a mixture of things, like why someone's skin is darker, or lighter or like in my case, I'm in my 30's, I'm a male, and have no body hair.  So you'd have to think that there's many factors involved.

Hair color comes from melanin (say: meh-luh-nun), the substance that gives hair and skin its pigment. The lighter someone's hair, the less melanin there is. A person with brown or black hair has much more melanin than someone with blond or red hair. Older people lose the melanin pigment in their hair as they age, making their hair look gray or white.

Your friend is correct. I just studied this in school. Dark hair always dominates light hair. And the allele for green eyes overpowers the allele for blue eyes.

It is heredity. Skin pigmentation is a polygenic trait i.e it is controlled by more than one gene producing a myriad of phenotypes. Some gene combinations make a person produce more melanin than others. Black people have a gene combination that makes them produce a lot of melanin, white people produce way less melanin.

The different skin colors have evolved as response to the different environmental conditions in which the various populations (don't call it "races": any modern biologist refuses this concept as meaningless) have developed.\nIt is generally accepted that Homo Sapiens originated in Africa, then gradually migrated to the other continents, especially after the introduction of agriculture and the consequent demographic explosion. Our African ancestors must have been all black, because at those latitudes the skin needs to protect from sun rays and this protection is achieved by dark pigments.\nMoving to the north, where the sun is weaker, an intense pigmentation was no longer an evolutionary advantage, but a flaw, because another effect of sun exposure is to trigger D vitamin production. Therefore, in thousands of years, the skin of northern people gradually changed to white.\nNote that the reverse is also true: Australian natives are darker than their ancestors migrating north to south from Asia.\nIn conclusion, the skin color is just the result of a balance between the need for skin protection (prevent skin cancer) and that for skin transparency (promote D vitamin production).

Because it has to do with genetics.  If your parents had brown hair then most likely you will have the same color.  If they have blond hair then you may also get blond hair.  It all depends on your genes.

Because we were separated into tribes and races so we would be more recognizeable.  So we can tell eachother apart.  If all there were were one set of traits (Ie: black hair and brown eyes) it would be pretty hard to tell us all apart.
