The epidermis is the top layer of skin!
Answer:
A: Natural selection would likely have selected for humans with little skin pigmentation
Explanation:
Sunlight/UV radiation has been discovered to be an inducer of immediate pigment darkening or melanin production. Hence, if a sunlight/UV radiation shield is is constructed to limit the amount of radiation that reaches the earth, after a while, this might become a selection factor.
Natural selection would likely have selected for humans with little skin pigmentation, those that are able to successfully adapt to the effects of limited sunlight/uv radiation. Humans who are not able to adapt to limited sunlight/uv radiation eventually get replaced in the population by those that are well adapted.
<em>According to theory of natural selection which was proposed by Darwin,</em> organisms with heritable traits that enable them to adapt to changes in an environment will survive more and produce offspring which are also able to survive. This eventually leads to eventual dominance of well adapted organisms in the environment over those that are not able to or weakly adapted.
<em>The correct option is A</em>
