5. Which of the following evolutionary processes (leading to speciation) is based on random changes population gene frequencies, due to a sudden decline in population size, followed by a recovery? A. migration (1like the evolution of Galapagos Island finches from one South American finch species B. genetic drift (like the evolution of sinistral-coiling snails from dextral-coiling ancestral snails) C. mutation (like the evolution of a new strain of influenza virus from an old ancestral strain) D. natural selection (like the environmental selection of polar bears from ancestral brown bears) E. artificial selection (like the human-directed selection of friendly dogs from ancestral gray wolves)
