front 24 Urban rats have resisted effects to poison them out because they: | back 24 Breed rapidly and evolve by natural selection |
front 25 Which of the following evolve? -Population -Genera -Kingdoms -Individuals | back 25 Populations |
front 26 Wings of insects and birds are result of convergent evolution. This means that: | back 26 Insects and birds have each independently evolved structures that serve the same function (flight) but have done so in very different ways |
front 27 The presence of vestigial organs supports evidence of evolution because: | back 27 The vestigial organ is similar to a functional organ in a related species, having been passed down from a common ancestor. |
front 28 The wing of a bird and the wing of an insect are: | back 28 Homologous structures |
front 29 When comparing chick and pig embryos, the similar eyes, pharyngeal pouches, and post-anal tails are evidence of: | back 29 Common ancestry |
front 30 Natural selection results in: | back 30 Offspring being better adapted to their current environment |
front 31 According to Darwin, natural selection is based on the ______ found in populations: | back 31 Variations |
front 32 The fossil record is incomplete because: | back 32 -Very few organisms were preserved as fossils -Organisms tend to decay before becoming a fossil -Geological processes may destroy fossils |
front 33 The forelimbs of early mammals were similar in all features except: | back 33 Function |
front 34 New alleles arise by: | back 34 Mutation |
front 35 If the frequency of a recessive allele is 36 percent, the frequency of the dominant allele would be what percent? | back 35 64 |
front 36 A species is composed of: | back 36 Organisms that have the potential to interbreed and produce fertile offspring |
front 37 Which of the following does not generate genetic variation within a population? | back 37 Adaptation |
front 38 All of the genes and all of their associated alleles within a population represent the population's: | back 38 Gene Pool |
front 39 Dominance causes an allele to become more common: | back 39 False |

front 43 Although Lamarck hypothesized that adaptations to the environment did occur, he also believed that offspring inherited characteristics acquired by their parents during their lifetime: | back 43 True |
front 44 Lamarck's hypothesis has since been discredited by Darwin's theory of natural selection: | back 44 True |
front 45 The observation that different geographical areas sometimes exhibit plant and animal communities of similar appearance, even though the individual plants and animals are not closely related, is called: | back 45 Convergent Evolution |
front 46 The key point in Darwin's proposal is that the ______ imposes the conditions that determine the direction of selection: | back 46 Environment |
front 47 Natural selection, as a mechanism of evolution that, acts on variants within populations and ultimately leads to the evolution of different species was proposed by: | back 47 Darwin |
front 48 Darwin proposed that natural selection occurs in an environment by: | back 48 Favoring heritable features that make the organism better suited to survive and reproduce |
