Explain Why Humans Have Different Skin Colorations

These two fundamentals inheritance along the mother line and occasional mutation allow geneticists to reconstruct ancient genetic prehistory from the variations in mtDNA types that occur today around the world. Eumelanin is brown or black pigmentation and pheomelanin is.

Human Skin Color Variation The Smithsonian Institution S Human Origins Program

Versus humans need at.

. Put simply dark complexion is advantageous in sunnier places whereas fair skin fairs better in. There is no specific scripture that explains why God created people with different skin color. This means that humans are all brown in color but they have different shades from dark to light.

Features such as hair colour skin colour eye colour and other physical features are somewhat affected by the environment in which they live in. Most people are familiar with the DNA that is found within the nucleus of a cell but by tracing mitochondrial DNA mtDNA lines scientists have been able to figure out when the human ancestors began moving out of Africa into different climates. He changed the genetic fabric of the races.

Theres a convincing explanation for why human skin tone varies as a global gradient with the darkest populations around the equator and the lightest ones near the poles. People with a lot of melanin have darker skin. There are three ways people can end up with different skin color.

God changed our language and our skin color to hinder us from uniting as one nation for the purpose of pursuing evil. Many people are under the misconception that there are different skin colors like red black white yellow and so on. People with less melanin have lighter skin.

People would have moved around the world but they would have still kept their skin color DNA. Why are people different colorsblack yellow brown etc. While this may explain different skin colors adaptation to different levels of sunlight or hair color accidentally more blondes settled in Scandinavia it does not explain why facial shape differs in.

There would have been a huge evolutionary pressure because of deficiencies in vitamin D although thats not the only factor which causes problems with calcium absorption for example and so lighter skinned people in colder climates would have thrived. But really we all have the same basic skin color from the main pigment in our skin called melanin. Alternatively theres also the idea that when your skin is heavily pigmented it means it protects you against UV light but actually you need certain amount of UV light to synthesise vitamin D in your body.

Humans have different skin colors because we have different amounts and kinds of the pigment melanin in our skin. Human skin color reflects an evolutionary balancing act tens of thousands of years in the making. No more than why He explained the creation of thousands of species of animals birds fish insects flowers etc.

A natural mutation modifying the mtDNA in the reproductive cells of one woman will from then on characterize her descendants. By Jablonski and Chaplins explanation there are two competing forces affecting human skin color. A new study shows the genetic picture behind skin color is far more.

No more than why He explained the creation of different heights or facial features. Answer 1 of 4. How does the Bible explain the origin of different races.

As early humans moved into hot open environments in search of food and water one big challenge was keeping cool. This is because skin colour is controlled by how much melanin it contains and melanin absorbs light and therefore UV. All living things have pigment and pigment makes color.

The Bible does not give us a specific answer to why people are different color the following information from The Bible Has the Answer by Henry M. They also would have been more people living all over the world and peoples skin colors would have changed slowly over the years and living at higher altitudes would have caused more variation because the amount of exposure would have varied as people moved around the world. Melanin is a pigment that forms the shades of brown.

Morris and Martin E. A short educational video for kids explaining why humans have different skin colors. Clark will add some insight on this issue.

The answer to why skin color is different for different individuals lies within your DNA. The melanin that produces the darker tones of human skin serves as a light filter to protect against too much UV light getting under the human skin where too much UV causes sunburn and disrupts the synthesis of precursors necessary to make human DNA. The third way is a bit more complicated and has to do with the kind of pigment someone makes.

Scientists used to think that the same small handful of genes accounted for about half of all pigment variation in human skin. Melanin also causes a zebras stripes a leopards spots and a frogs speckles. However the real answer is actually in a persons genetics.

There are two types of melanin. God may have used sun exposure to over time bring about changes in skin tones as those who live closer to the equator tend to have darker skins. In addition to their skin people have melanin pigment in their eyes and.

So when the amount of UV light youre getting is lower say when youre living in a northern climate then that means that its beneficial to actually increase. One way is that lesser the pigmentation lighter the skin. Variations in features occur with genetic variation.

But skin cancers Jablonski knew almost always arise later in life when an individual is past reproductive age. Theory held that darker skin had evolved in order to afford early humanswho had recently lost the cover of fura protection against skin cancer under the tropical sun. But there is an implied understanding of Gods personality through His design of.

Variations in human skin color are adaptive traits that correlate closely with geography and the suns ultraviolet UV radiation. Various theories have been suggested including sexual selection for different skin tones in different places but because of the strong correlation between pigmentation and amount of sunlight biologists have suggested that pigmentation differences are a result of natural selection imposed by different light levels in different places. This was a judgment on all of us.

People have different colors of skin because of a chemical in the skin called melanin. This pigment is a brown color. That is humans look different because they lived in different circumstances.

Our closest living relatives the chimpanzees have pale skin without melanin underneath their dark fur and almost certainly the ancestor that we share with chimps did too. Another way is when people have fewer melanocytes.
