High levels of solar radiation is one of many ways that can negatively impact humans as well as influence environmental stress. This includes sunburns, skin cancer, etc. Radiation can interrupt the process of radiation because with sunburn, tissue is broken down and damaged. This can happen with the absence of sunscreen due to radiation on skin contact. Although specific UV rays are healthy for the human body, too much is not. This
A sunburn is an example of an adaptation in which humans have created a short term solution for. Although this is a temporary example, the skin is known to swell as well as turn a reddish color in which thickens the top layer of tissue resulting in scarring or peeling of the skin. A differentiation of the pigmentation in the skin color is an adaptation of facultative stress. The melanin in the skin cells become damaged from the heat let off of the UV rays and begin to create something referred to as “sunspots.” This pigmentation can include darker and/or lighter patches of the sin. Developmental stress depends on one's phenotype, being their skin color. While one with a lighter skin color burns easier than a darker skin color, that is due to the amount of melanin. Someone with a darker skin color contains more melanin than those with lighter skin colors. People often tan to influence a darker tone in their skin. This could also be imitated through a spray tan in which refers to cultural stress.
Benefits of studying human variation is gaining knowledge of how human traits are distinct from others. This assists the theory of how the human ancestors may have potentially looked. By studying the effects of radiation for example, scientists are able to conclude a potential way of preventing skin disease and skin cancer due to high solar radiation.
Although race appears to be a distinctive matter between skin colors, it is simply just a matter of the amount of melanin a person has, cause a higher or lower amount of pigmentation. This is dependant on solar radiation and how is may slightly change one's sin color more effectively than others. With the scientific research of melanin and pigmentation in different bodies causing one human to look slightly different than another, it does not categorize people; instead it provide scientific facts.
