Genetic and environmental factors in skin color determination

Abstract

The origin of skin color has been significantly a discussion of importance among human biology scientists, anthropologists and others interested in evolution of human skin color. Experience was done to chimpanzee and other primates shared almost the same characters with mankind, and this impressed scientists to know what makes difference in skin color among people. Different researches conducted to know the real cause of dark skin and light skin among people of the same origin. There are no other results found out of permanent variation happened to our ancestors based on geographical location. Environmental factors played a huge role in skin color determination. High UVR has been led to dark skin color and low production of UVR led to lightly skin. By natural selection genes responded to environmental conditions for a human to survive in his own environment. Melanin production came as a response to UVR to protect against consequence of UVR in low latitude regions. Depigmentation happened due migration from low latitude to high latitude regions and led lightly skinned color for our ancestors. Everyone has skin color due to ancestry antique geographical location.

Insights Into the Albinism Mechanism for Two Distinct Color Morphs of Northern Snakehead, Channa argus Through Histological and Transcriptome Analyses

“…Meanwhile, the signal transduction (31) and signaling molecules and interaction (37) of environmental information processing, global and overview maps (30) of metabolism showed the highest proportion according to the KEGG pathway classification. These results indicate that the environmental factors may have a huge contribution to the formation of different body colors of aquatic species (Cheng, 2008;Yadufashije and Samuel, 2019), and we inferred that the different body colors of C. argus might be closely related to the geographical environment, but further research and verification need to be investigated.…”

The Impact of Bias and Discrimination

“…Melanin is a complex biological pigment present in skin, hair, eyes, ears, and the nervous system (ElObeid et al, 2017). Differences in skin color resulted from evolution in response to environmental factors, with high ultraviolet radiation resulting in dark skin color and low ultraviolet radiation leading to light skin color (Yadufashije & Samuel, 2019). Melanin has two forms: pheomelanin (yellow-reddish), accumulated in light complexion people, and eumelanin (black-brown), produced in dark complexion people.…”
