- 1. 13.) Check out the tree on the right. Given the information in this tree, which statement about primates and rodents/rabbits is true? a) They both have pre-orbital fenestra. b) Only rodents and rabbits have preorbital fenestra. c) They both have hair. d) Only primates form an amniotic egg. e) Rodents and rabbits are most closely related to crocodiles 14.) Use the tree from question 13 to answer the following; ray-finned fish are more closely related to primates than to sharks, a) True b) False 15.) The rise of methicillin-resistant Staphylococcus aureus (MRSA) can be considered an example of artificial selection because: a) humans purposefully raise MRSA in large fermenters in an attempt to make the bacteria evermore resistant b) S. aureus is cultivated by humans to replenish the soil with nutrients c) humans synthesize methicillin and create environments in which bacteria frequently come into contact with methicillin d) humans are becoming resistant to bacteria by taking methicillin 16.) Which of the following statements best summarizes evolution as it is viewed today? a) It represents the result of selection for acquired characteristics b) It is synonymous with the process of gene flow c) It is the descent of humans from the present-day great apes d) It is the differential survival and reproduction of the most-fit phenotypes 17.) Dogs (Canis lupus familiaris) and gray wolves (Canis lupus) can interbreed to produce viable, fertile offspring. These species shared a common ancestor recently (in geologic time) and have a high degree of genetic similarity, although their anatomies vary widely. Judging from this evidence, which two species concepts are most likely to place dogs and wolves together into a single species? a) ecological and morphological b) ecological and phylogenetic c) morphological and phylogenetic d) biological and morphological e) biological and phylogenetic 18.) Linnaeus was a "fixist" who believed that species remained fixed in the form in which they had been created. Linnaeus would have been uncomfortable with: a) classifying organisms using the morphospecies concept b) the scientific discipline known as taxonomy c) phylogenies d) nested, ever-more inclusive categories of organisms e) a hierarchical classification scheme
