Why do African Americans have such curly hair?

Question

Does it have anything to do with the climate or some other local condition their heritage originated from? Any answers? Some friends and I were having a multi cultural discussion and we decided to put it out to the public on this subject.

Answer 1

Because our hair does not produce oil, therefore it is not weighed down and straight like other races.
Also, we do not have to wash our hair everyday because of the lack of oil. In fact, we have to put oil into our hair to lubricate it.

Answer 2

Not all African Americans have curly hair. But I have curly hair. Back when slavery was still in effect, some slaves would get raped by the slaveowners and produce children. So I figure that and other interracial relations may be where a good number of black people get curly hair. Or maybe curly hair just runs in their family. Who knows.

Answer 3

Curly hair is the genetic "norm." It retains heat better and provides better protection from the elements.

Flat hair on humans is a genetic anomaly. The hair provides no real benefit. Archaeological evidence suggests humans with a mutation that caused flat hair didn't survive in the wild until humans learned to make clothing from the hides of dead prey.

In other words, flat haired humans are a genetic freak that can only survive because of the ability to make tools.

Answer 4

I read years ago that the differences in hair type are due to the shape of the hair. African Americans have hair with an oval, nearly flat, cross-section, which makes it curl.

Answer 5

It's a genetic trait. African-American people have hair whose cross section seen under a microscope is elliptical. Caucasian or white-colored people have also that trait but less pronounced, going from somewhat elliptical to almost circular. Far-East people have a definitely circular hair cross-sections, which give then that specific "flat hair" appearance.

Answer 6

Do they comprehend that it is strictly 13.7 billion years? No. it particularly is how technological information works. technological information is often attaining for the reality, whilst recognizing that they might constantly be fallacious (in assessment to three different varieties of human corporation). The cosmic history radiation became envisioned to be got here upon, based on the approximate age of the universe. on the time of the prediction, no one had yet seen it. It became later got here upon (somewhat by ability of twist of destiny) and it matched the envisioned absolute temperature value interior of a fragment of a level. Now, you may declare that that became purely guesswork. yet some adult males positioned their expert reputations on the line to make that prediction. and another adult males worked very difficult to make beneficial that what became at last got here upon matched that prediction precisely. yet that's no longer the only piece of the puzzle. There are a number of self reliant efforts that got here up with ends up of their very own. those are thoroughly separate and unrelated to the cosmic history radiation. they contain examine like: a million. length of redshift interior the easy spectra from distant galaxies. 2. Chemical composition of famous individual populations and nebulae interior the seen universe. 3. Radioactive relationship of rocks interior of our very own image voltaic gadget (Earth, Moon, meteorites, and so on). 4. Chemical makeup of the universe as an entire. there are various, many others. They fill libraries. the component is: all of them arise with a similar answer. and that all of them reached that very same answer from distinctive instructions. might desire to they be incorrect? actual. Is there an blunders band? of direction. although this is not purely hypothesis, and this is not guesswork, in spite of the undeniable fact that it is knowledgeable. it is technological information. The evidence is overwhelming, and this is the terrific answer that we've, till a greater powerful one is got here upon.

Answer 7

Some of us have a mixture of different cultural and racial backgrounds. Some hair textures will skip one generation and go to the next. My first daughter is lightest out of my three and has extremely curly hair. Shehas my grandmothers features

Answer 8

Kinky hair is dense and tight. I guess its to protect our skulls from the unrelenting heat of the plains of Africa not to mention the unfiltered sun beams and a lot of villages have no shady trees or bush or whatever.

I think the more forested regions, they may not have hair as kinky as the Sahara region, but I'm just guessing.

Answer 9

Ok why are you asking soooooooooooooooo many questions about africans do you wanna be one?????? Im black and I dont have curly hair, mostly all the african people at my school dont have curly hair?

Answer 10

Modern human beings whose distant ancestors stayed in Africa developed taller, thinner bodies that exposed a lot of skin and that the air could therefore cool more easily. Darker pigmentation in their skin (almost surely the "original" color of all human beings) protected them from the tropical sun's UV rays, and their tight-curled hair protected their heads from the heat. But humans who had migrated out of Africa into Europe or Asia , coping with long dark winters, had other "needs". To keep their bones from weakening, they needed sunlight to stimulate vitamin D production. Their (again, almost surely, originally dark) skins would have blocked out too much sun, so they developed pinkish or sallow skins with little pigment. Bear in mind these changes took place tens and tens of thousands of years ago, in prehistoric times, and they took place very very slowly, as a type of evolutionary adaptation to environmental changes (possibly or probably coupled with sexual selection as well). The process would have been glacially slow, and likely took thousands of years to actually happen.

Answer 11

Since you were having a multi cultural discussion, did you have any African Americans there, because if you did you could've asked them. I would have been nice since discussing multicultural races that all races would be involved.
