A Team of Scientists Plans to Study Divergence of Populations

A team of scientists plans to study divergence of populations and needs to maximize the rate of divergence to see results within the period of their grant funding. They will form a new population by taking some individuals from a source population and isolating them so the source and new populations cannot interbreed. Which of the following strategies would maximize the likelihood of seeing divergence between the source and new populations in this study?

A) choosing individuals with the most common phenotype in the source population to form the new population and placing the new population in the same type of an environment as the source population
B) choosing individuals with the most common phenotype in the source population to form the new population and placing the new population in a novel environment as compared to that of the source population
C) choosing individuals from one extreme of the source population to form the new population and placing the new population in the same type of an environment as the source population
D) choosing individuals from one extreme of the source population to form the new population and placing the new population in a novel environment
