Someone please show me how skin colour evolved over time.?

i want to see pictures of how skin colour evolved from chimpanzees to curent day humans. Not just skin colour but also hair on skin. the whole works

I think you are looking at it from the wrong prospective, I wouldnt look at the melanin correlation in chimps or other great apes as to humans. Melanin is the pigment in our skin that helps protect us from the harmful Uv radiation that is present in our everyday lives.

"Dermal melanin is produced by melanocytes, which are found in the stratum basale of the epidermis. Although human beings generally possess a similar concentration of melanocytes in their skin, the melanocytes in some individuals and races more frequently or less frequently express the melanin-producing genes, thereby conferring a greater or lesser concentration of skin melanin. Some individual animals and humans have no or very little melanin in their bodies, which is a condition known as albinism." Wiki.

Therefore, you would see that certain races where melanin was more needed due to their living conditions would have more genes that would express the pigment. If you look at the trend of the globe, enviroments that arent on the poles or on the equator tend to have lighter skinned individuals.Its because they arent getting the direct sunlight/uv radiation that the people on the poles or the equator are getting.

Now there is also the fact that there are different races of human and that these races tend to express pigments very differently from eachother. Such as why chimps are lighter skinned than gorillas... (not exactly a great example, but it will do) over long periods of time natural selection causes fluctuations in these trends, and now that we are seeing increased radiation, those that have stronger forms of melanin and a smaller predisposition to cancer tend to "pass on their genes" or have better reproductive success. Now, this is all relative and I could probably go on for hours about it, but in todays society since we arent nomadic / are particularily sedentary, if you tend to have darker or lighter skin colors it is due to your heratige.

No! Get it right the first time!

The joke goes...

God! Why is my skin so black?

*To protect you from the sun my child!

God? Why is my hair so kinky and close to the scalp?

*To protect it from the high vines and brambles!

God? Why are my nostrils so big?

*To accept enough oxygen in the thin air!

God? Than what the God Damn Hell an I doing in Washington D.C.?

God! To force a democracy! A Republic would work, and much of those in government say If it works...Change It!

OK first off we did not evolve from chimps all great apes including man had a common ancestor and proceeded down different evolutionary roads, if your teacher said differently he/she is an idiot and should not be teaching biology. and what you are asking for is impossible, scientists are still looking for fossil records for proof of evolution. how would we have pictures of something that occurred millions of years ago? and human skin variation among humans is a result of different adaptations to climate. dark skinned people with wide nostrils developed in equatorial regions with intense direct sun exposure and high temperature. dark skin for protection from the sun and large nostrils and sinus cavities to cool the brain. light skin evolved when humans spread to climates were the intensity of sunlight was less they had to lose melanin (pigment in skin) in order to get enough energy for vitamin D production and smaller sinus cavities to conserve heat in the colder climate.
