Answer:
The loss of fur is a protection mechanism for the epithelium that covers us, over the years this method of protection was replaced by the protection provided by melanocytes with their melanin, therefore people who had a low presence of melanin could not survive in the evolution.
Explanation:
The presence of melanocytes and melanin in the skin is what protects it against ultraviolet radiation, over time the human being was affected by solar radiation, thus being one of the causes of bipedalism.
In those humans where melanin is defective or a small number of melanocytes are more predisposed to suffer epithelial pathologies today.
Human evolution then led to hair loss and increased epithelial tonality, causing those who could not have this phenotypic quality to be extinct or deceased.

Protein synthesis from gene transcription and translation. The N for amino acids comes from Nitrogen fixation
The places where carbon can be found are in plants, animals, grasses, fossil fuels, soil, atmosphere, decomposition, combustion and in food macro molecules.
Carbon from the atmosphere enters into the plant during photosynthesis and this is passed on to the sugars produced in the plants and unto man eventually when man eat this plants or feed on animals which had eating these plants.<span />
