Which of the following best explains the role mutations play in natural selection?A. Most mutations are negative and result in the extinction of the entire speciesB. Mutations may appear for one or two generations, but they usually disappear quickly.C. If the environment changes, an existing organism develops a mutation that will help them to survive.D.

- 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
- The process by which evolution occurs is calleda. natural selection. b. development. c. reproduction. d. taxonomy.arrow_forwardHow 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_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
- Which of Darwin's five 'theories' was something that he strongly emphasized but that we now think is a bit over emphasized on his part. 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_forwardCharles Darwin proposed that evolution could be explained by the differential reproductive success of organisms that resulted from their naturally occurring variation. Darwin called this process (a) coevolution (b) convergent evolution (c) natural selection (d) artificial selection (e) homoplasyarrow_forwardWhich of the following is not part of Darwins mechanism of evolution? (a) differential reproductive success (b) variation in a population (c) inheritance of acquired (nongenetic) traits (d) overproduction of offspring (e) struggle for existencearrow_forward
- Indicate whether each of the following statements about natural selection is true (T) or false (F). Put either a T or an F in each box provided. a. Natural selection alters a population's gene pool b. Natural selection creates new alleles which increase the reproductive success of their owners c. Natural selection favors traits which it anticipates will be beneficial to a species in the future d. Natural selection can at times be observed in nature over the course of just a few decades e. Natural selection acts directly on an individual's phenotypearrow_forwardWhich aspect(s) of natural selection is(are) illustrated by the figure below? Check ALL answers that apply. A. Variation among individuals must be genetically transmissible to the next generation. B. Variation must exist in a population. C. Variation among individuals leads to differences in lifetime reproductive success. D. More individuals are produced each generation than the environment can support, resulting in competition for survival.arrow_forwardEvolution is a theory, so it is still only tentative. Once it is really a meaningful scientific discipline, it will become a law. Select one: O True O False Darwin was meticulous in making several key observations that formed the foundation of his argument for his theory of evolution. Which of the following did Darwin NOT use in the formulation of his theory? Select one: O a. Variation exists in populations. b. There is a culling among offspring. c. Keystone species are infrequently found in disturbed communities. d. Traits are inherited across generations. e. Individuals reproduce in excess. A bison walks through a prairie, foraging on grass. As it walks, it kicks up insects which are then eaten by brown-headed cowbirds. Match the relationships below with their appropriate type of dyadic interaction. Bison Grass Choose... Choose...
