OA by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population
B. by producing offspring with new gene assortments from genetic recombination, which increases diversity in a population
OC. by mutating their DNA in response to environmental conditions to gain beneficial traits
OD. by adapting to changes in environmental conditions without undergoing changes in their DNA
