The intensity of SAD can vary across individuals; some individuals can suffer serious depression and suicidal thoughts, while others feel mild depression.

This disease impairs the ability of the body to repair DNA which is damaged mainly by Ultraviolent light as well as various chemical Carcinogens. ” The most common forms of DNA damage occurs via the cross linking of adjacent pyrimidines resulting in the formation of cyclobutane pyrimidine dimers (CPDs)” (1) for example UV light will often make two T 's…

Skin pigmentation mutation: Melanin is a pigment which changes the colour of skin in humans. The more melanin in our skin the darker our skin colour is. Homo sapiens originally had a white-pink skin colour and they were covered in hair. Over time we grew less and less hair on our bodies resulting in less protection from the sun and its harmful ultraviolet (UV) radiation. In the very northern or southern countries, areas further away from the equator, there is less exposure to UV radiation due…

With attention to the prominent phenotype that immediately divides individuals from each other-skin color is due to melanin. Cameron and Wycoff explained why there is darker skin color, "Melanin migrates to the skin's surface when stimulated by the sunlight to produce darker skin, protect the body from the harmful effects of the sun's ultraviolent rays, and to decrease the production of toxic levels of…
