Quizplus · Accepted Answer

Requirements for evolution by natural selection are differential survival and reproduction (II), heritability of phenotypic variation (III), and variation in phenotype (IV). Environmental change (I) and sexual reproduction (V) can influence the direction and rate of evolution but are not absolute requirements for natural selection to occur. Therefore, the best choice is II, III, and IV (B).
