Biology, 7e (Campbell) Chapter 25: Phylogeny and Systematics 1) Which combination of the following species characteristics would cause the greatest likelihood of fossilization in sedimentary rock? I. The species was abundant. II. The species was widespread. III. The species had hard body parts. IV. The species was adapted to desert life. V. The species had a long duration in geologic time. A) III only B) III and IV C) I, II, and III D) I, II, and V E) I, II, III, and V 4) Some molecular data place the giant panda in the bear family (Ursidae) but place the lesser panda in the raccoon family (Procyonidae). The morphological similarities of these two species must therefore be due to 5) The correct sequence from the most to the least comprehensive of the taxonomic levels listed here is B) kingdom, phylum, class, order, family, genus, and species. 6) The common house fly belongs to all of the following taxa. Assuming you had access to textbooks or other scientific literature, knowing which of the following should provide you with the greatest amount of detailed information about this specific organism? 7) Panthera is a taxon at which level? 8) If organisms A, B, and C belong to the same class but to different orders and if organisms D, E, and F belong to the same order but to different families, which of the following pairs of organisms would be expected to show the greatest degree of structural homology? B) A and C C) B and D D) C and F E) D and F 9) On the basis of their morphologies, how might Linnaeus have classified the Hawaiian silverswords? A) He would have placed them all in the same species. B) He probably would have classified them the same way that modern botanists do. C) He would have placed them in more species than modern botanists do. D) He would have used evolutionary relatedness as the primary criterion for their classification. E) Both B and D are correct. 10) Darwin analogized the effects of evolution as the above-ground portion of a many-branched tree, with extant
