Unformatted text preview: • Explain why an individual organism cannot evolve Concept 22.3: Evolution is supported by an overwhelming amount of scientific evidence • Describe the experiments that supported Reznick and Endler’s hypothesis that differences in life-history traits between guppy populations are due to selective pressure based on predation. • Explain how drug resistance develops in HIV • Explain how the existence of homologous and vestigial structures can be explained by Darwin’s theory of natural selection. • What observations have been made regarding the fossil record. What predictions can be made using evolution to account for the distribution of fossils in sediments. • Explain how biogeography is used to infer the evolution of organisms...
