b.Evolution has altered and diversified ancestral species.
c.Evolution occurs inindividuals rather than in groups.
d.Natural selection eliminates unsuccessful variations.

- Darwin’s Theory of Natural Selection occurs in 4 steps.Which of the following is NOT one of these four steps?a. Differentiationb. Selectionc. Competitiond. Overproductionarrow_forwardAlfred 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_forwardWhich of the following statements does NOT agree with the tenets of Darwin's theory of evolution by means of natural selection? O A. The phenotypes of individuals in a population will differ and, in some cases, these differences are the result of traits passed down from parent to offspring. B. Phenotypes become more common over time if individuals with those phenotypes have higher reproductive success. O C. The fitness of an individual with a particular phenotype is independent of the environmental conditions it experiences. O D. Resources limit the total number of individuals in a population.arrow_forward

Group of answer choices A. evolution has happened B. evolution is a process of change and splitting C. evolution is a very slow and gradual process D.all life has a common ancestor E.natural selection is the primary force causing evolutionarrow_forwardWhat is meant by the following statement? "When mutation is random, natural selection is not." Mark all correct answers Group of answer choices A. A mutation is caused by changes in the environment. B. Natural selection can favor some mutations and not others. C.Mutations for advantageous traits are more likely to be passed on to the next generation. D.Selection can change depending on the environment.arrow_forward
- How did Darwin support the idea that natural selection can produce evolutionary change? Group of answer choices A. he examined how humans produced domesticated plant and animal breeds B. he just thought it had to be true C. he invented a time machine to go back and check it out for himself D. he observed wild populations to see natural selection in actionarrow_forwardCharles Darwin proposed that evolution could be explained by the differential reproductive success of organisms that resulted from their naturally occurring variation.
