- Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a populationarrow_forwardNatural selection operates on populations over many generations. Which of the following allows natural selection to occur? A. the desire and the advantage of a population to remain constant B. the old age of the individuals which causes them to die C. the abilty for populations to change quickly from one trait to the next D. the unequal ability of individuals to survive and reproducearrow_forwardWhen taking the question, it would appear as: Consider global warming, a continual gradual increase in average temperatures. How might you expect this to affect natural selection? A.environmental changes are unpredictable, and natural selection is a random process, so it is difficult to predict outcome B.species from warmer climates are likely to expand their ranges into higher latitudes C.traits that increase reproductive success under warmer temperatures are likely to increase in frequency in a population D.the stress caused by higher temperatures will increase mutation ratesarrow_forward
- Which of the evolutionary processes discussed in the material presented can introduce genetic variation into a population? a) natural selection and genetic drift b) mutation and gene flow c) natural selection and nonrandom mating d) mutation and genetic driftarrow_forwardWhich of the following is true about adaptation? a) It occurs through the inheritance of acquired characteristics b) It always results in the evolution of new traits c) It is a result of chance mutations d) It is the result of natural selection acting on heritable variationarrow_forwardWhat is the difference between artificial selection (e.g., greyhounds that are bred for speed) and natural selection? a. In artificial selection, the genetic variation introduced into the population is limited, but in natural selection, it is not b. In artificial selection, the environment is the selective force, while in natural selection, humans are the selective force c. In natural selection, the environment is the selective force, while in artificial selection, humans are the selective force d. Unlike other species, dogs are not subject to natural selection e.

- Which of the following promotes adaptive evolution in populations? A)High genetic diversity B)Selection pressure for an environmental factor that is changing C)Greater survival and reproduction in organisms with inherited traits D)All of the above At what rate do adaptations occur in populations? A)Adaptations occur slowly, due to very low mutation rates. B)Adaptations occur quickly, due to the ability of organisms to quickly acquire traits from their environment. C)Adaptation rates can be fast when selection pressures are strong. D)Adaptation rates are always slow, due to genetic drift. Gene flow among populations results in which impact on adaptation? A)It increases the occurrence of adaptation by introducing new genes. B)It slows the process of adaptation by introducing alleles that keep the population from being dominated by the alleles best suited for the environment. C)It increases the occurrence of adaptation by moving traits acquired…arrow_forwardThe best argument for how an unprotected species can evolve to mimic a second protected species (distasteful or noxious) and thus obtain protection is by A. Random changes in the appearance of the unprotected species that lead to increased fitness due to greater similarity with the protected species B. Individuals deciding that they need protection and mutating to look like the protected species C. Individuals changing their diet to increase pigment production to look like the protected species D. Natural selection for more advanced traits that are better to the inferior traits of organisms that do not look like the protected species E. Behavioral modification of the unprotected species to act like the protected speciesarrow_forwardWhich evolutionary forces a. cause an increase in genetic variation both within and between populations? b. cause a decrease in genetic variation both within and between populations? c. cause an increase in genetic variation within populations but cause a decrease in genetic variation between populations?arrow_forward
- a. What effect does combining genetic drift and natural selection have on beneficial mutations? b. How would you it change if population size increasesarrow_forwardWhen we take, say, 100 individuals of a species of beetle from the wild and place them in a new environment that is not so different that they are unable to thrive but different enough so that they are experiencing a new selective regime, say, a lower temperature, what typically happens? A - Sexual selection causes some larvae to be able to survive in the cooler temperatures and other individuals to be unable to survive because they need warmer temperatures. B - We are unable to measure phenotypic selection, presumably because we do not have much variation among individuals for how they handle temperature. C - The founder event assures us that the new population will be strictly representative of the source population (especially if we took all the 100 from the same location rather that from throughout the range of the species). D - The population evolves to be tolerant of the lower temperature; it can do this because of latent variation already in the 100 founding individuals. E -…arrow_forwardWhich of the following evolutionary forces can introduce new genetic variation into a population? a. natural selection and genetic drift b. mutation and gene flow c. natural selection and nonrandom mating d. mutation and genetic driftarrow_forward
