Human Skin Color Evidence For Selection Answer Key
Human Skin Color Evidence For Selection Answer Key. Our research on the evolution of human skin and skin color has demonstrated that skin color is the product of natural selection acting to regulate levels of melanin pigment in the skin relative. Helen snodgrass describes how she uses biointeractive's the biology of skin color film and evidence for selection activity to show students how humans have evolved.
