Biology of Skin Color

There are many features of the DNA code that are not well understood. One feature, which has been intensely studied in recent years, is the genetics of skin color. In basic evolutionary theory, skin color evolved from some ancient hominid trait that had an effect on survival. literature review format for thesis It was a useful strategy for an early human who wanted to blend in with his or her environment. The science of DNA testing has given many clues about how genes affected human skin color. A recent DNA study found that African American skin is lighter than that of Caucasian-Americans. This suggests that genes are partially responsible for this phenomenon. But, there is another side to the story. People who claim that there is a genetic influence on skin color are not stating an actual fact. They are merely stating a hypothetical that they claim is true. If a person’s ancestry includes, say, Native Americans, he or she may look much darker than a person who does not have Native American ancestry. The pattern of inheritance has not been seen, and it may not exist. Therefore, this is not an accurate statement about genetic inheritance. Scientists have found that the exact same form of DNA inheritance is responsible for characteristics which can be related to skin color. However not all characteristics are determined by enzymes. For example, weight and height are not influenced by enzymes. Physiology also plays a role in determining skin color. The way the body is built influences the way people look. The way the skin interacts with clothing also affects a person’s appearance. The way a person dresses can also affect how he or she looks. People who wear clothes made of synthetic fibers often appear more graceful and elegant. This could be a product of the design of the fibers. But, the effect is likely due to the way the fibers are put together. Clothing companies put much less thought into making clothes when they use synthetic fibers. This is because synthetic fibers do not allow air to pass through them, and so allow people to appear more graceful. Clothing also affects how folks search. How someone walks and moves will trigger a big change from the way he or she looks. Men and women who truly feel confident and stroll will be the absolute most likely to check. Perhaps the biggest contribution of the biology of skin color is the importance of clothing. Even clothing manufacturers understand that the way people look, can be influenced by how they dress. They try to design clothes that make people look better. Genetics and clothing are a perfect example of how important psychology is to the world. It’s amazing how certain things have been discovered through psychology and science, and yet have had such a profound effect on how we look and feel. The study of psychology and the study of genetics are two very different things, but they have a lot in common.
