I suspect that it is, but can not find empirical evidence, as I have sought to find the true answer of this question myself.
What is known is that due to the pigment, blacks take less sun damage, thus black skin wrinkles less than white skin.
I am not a racist by my definition. Yours may vary. I think there are differences between the races, but give everybody an individual evaluation. I have always been extremely inquisitive and notice much that others might not. This leads me to questions like this. I'm going to say some truths that are uncomfortable for some to hear.
1. Though the common saying is the only difference is the color of one's skin, this is not true. This is a foolish way to try to minimize racial differences. It is not helpful because we all know there are many differences between races than skin color and it leaves people either having to accept a lie, or leaving them on their own anger of being told that lie, possibly leading them to be racists.
2. Blacks have thicker, kinky hair.
3. Blacks have different shaped craniums. This is actually how scientist define the races - by skull shape. By the way there are only three races - Caucasoid (White), Mongoloid (Asian), and Negroid (Black).
4. Races are subject to their own diseases such as Sickle Cell, Psarcoidosis, etc.
5. The term "ashy" refers to the fact that blacks suffer from chronic dry skin. They also suffer from very dry scalps. This could mean it is thicker, thus making moisture hard to reach the most outer part.
6. Blacks have scientifically measured, smaller brains on average than other races. Big faces, small skull caps. They are closer to the location of the origin of man and have had less environmental pressure to have as many adaptations as other races have had.
7. American blacks have been bred by slave owners to select for certain genetic traits. Slaves were used for work and fighting. They were bred like livestock to develop certain traits. Tough skin was one of those for the fighting blacks. Size and muscularity were also bred for traits. This is one of the reason they are dominant in sports. Sports commentator Jimmy The Greek was fired for stating this truth.
8. All humans are a species of animal.
9. We document animal differences among different breeds, which if they weren't animals other than humans, we might call races.
10. Your personality and social characteristics are due in part due to your physical structure and chemical balance. This is why we can easily pick up a book that tells us what to expect from say a breed of Cocker Spaniel vs. say the breed of Labrador Retriever. They can breed and reproduce with each other, which defines the same species. However we further define the breed. We are afraid to admit that there are predictable differences between races of people.
11. Many will say if you say there are differences such as thicker skin on blacks than whites, then you are racist. If you are like me, you just want to understand all that you can know about your world and you have questions.
12. I think scientist downplay and do not document such differences due to social pressure. It is hard to find. Look at the uproar and death threats from the scientific evidence that The Bell Curve studies showed on brain size.
13. It is understandable that sometimes truths might be hard to take, like we as a race have smaller brains on average, and that this information will fuel racist to be...well...racists. That leaves us with a choice.
14. The choice is to suppress truths, because we are not adult enough to handle them, or to state known facts and educate people to celebrate differences, and that even differences perceived as negative are negligible and on average, and that individuals may differ from the average. Asians are generally short but Yao Min is very tall. Treat all as individuals. All possibilities exist.
15. So the short answer, it is hard to find the answer because it's not the kind of answer the public wants to have in their politically correct knowledge base. Good luck, and when you find a credible medical establishment siting empirical evidence about it, please let us all know.
All black people's feet are not white on the bottom. It is a matter of different skin tones.
If your skin is black there is nothing you can do to turn your skin white. Doctors can perform skin lightening procedures, but it is expensive and the results are not always good.
Lincoln was black and white
Jesus probably had a skin tone similar to modern-day Palestinians. Most people would consider that "white", but definitely more "Mediterranean" than "Nordic".He'd also probably say something along the lines of "and exactly what difference does that make, anyway"?
Because of peoples background, i.e. evolution. All peoople trace their history back to Africa, several million years ago.I agree. Here is ONE explanation.People who have roots in the Scandinavian countries have fairer skin tone. Recent, last ten years, research into the migration of the human species through DNA links the origin to south central Africa. A migration to north eastern Europe by the human population who had darker skin tone and eventually Scandanavia occurred after that. The need for the absorption of Vitamin D from sunlight caused those with lighter skin to be healthier in the less illuminated northern climates. Those with darker skin tone had a disadvantage. This is the conjecture of the variants of skin tones. In today's world we can supplement the diet with Vitamin D so there should be no evolutionary advantage for either skin tone and therefore no need for discrimination by skin tone.

If you are just meaning the skin color, they can be white or not, from blue-eyed and pale to black-eyed and very swarthy. But if your meaning "white" as "French and Portuguese are white peoples" and "Ethiopians and Sudanese are black peoples", then yes, they're white, unless you are to admit that Greeks, Jews, Maltese and Italians are not white. There is a big variation in skin hue among caucasian peoples, from the Afghanis to the Swedes - and no one is really "white", but pink to light brown, tan and olive. Being swarthy is one feat that a "white" person can have.
If you are mixed with white and black you are no longer white your skin is not fully white anymore and your hair isn't like white peoples hair any more but it might have that texture
It may vary: dark orange, brown, but it is not actually black.
skin is thicker on your feet
All black people do not have pink, or white or any certain color on the bottom of their feet. The bottom of their feet come in various tones just as their skin.
white
You can see that a panda has a black nose and the skin on the nose would be the skin that it has all over its body even though it looks like it has white skin because of its white fur. A panda bear has black skin like a zebra

Black peoples skin is dark because their is an abundance of sunlight in most of Africa and their dark skin prevents too much absorption of vitamin D. White people's skin is light because in most of Europe there is alot less sunlight and the skin is light to help absorb as much vitamin D as possible.
