- Alfred Russel Wallace and Charles Darwin argued that evolution by means of natural selection involves all of the following steps except: a. variation is present in all species b. species can produce more offspring than the environment can sustain c. all individuals within a species have equal chances to improve their fitness d. those individuals that are more fit will survive and reproduce in the greatest numbers e. over time, the species will evolve as the more fit individuals replace the less fit individualsarrow_forwardDarwin’s finches are a noteworthy case study of evolution by natural selection because evidence suggests a. they are descendants of many different species that colonized the Galápagos. b. they radiated from a single species that colonized the Galápagos. c. they are more closely related to mainland species than to one another. d. None of the choices is correct.arrow_forwardThe Galapagos archipelago consists of volcanic islands that formed within the last 5 million years.
