Environment Unpolluted woods Polluted woods Number of individuals taken by birds Light morph Dark morph 26 43 164 15 [LSC 3] Review the results of Kettlewell's (1950) experiment on peppered moths (above). Which of the following conclusions is BEST supported by this evidence? Sexual selection was a mechanism of evolution driving the increased frequency of dark morphs. Light colored moths survived better regardless of habitat, suggesting that their fitness was higher than that of the dark morphs. Natural selection favored different alleles for moth color in different environments. Genetic drift randomly changed allele frequencies over time in this population.
