1) Imagine you have two different groups of organisms. They look different and do not have any
recently derived traits in common. Which of the following is true?
A) According to the biological species concept, they are the same species.
B) When considering the morphospecies concept, they are the same species.
C) A cladist would say they are different species.
D) A pheneticist would say they are the same species.
E) The two groups of organisms are displaying a prezygotic isolation mechanism. - ANSWER:c
2) Two groups of organisms look alike, but have different alarm vocalizations. Which of the
following about this scenario is true?
A) The difference in alarm vocalizations is an example of a post-zygotic isolation mechanism.
B) The groups are different species based on the morphospecies concept.
C) The differences between the groups may lead to allopatric speciation.
D) Prezygotic isolation mechanisms likely caused the differences in vocalizations.
,E) Two of the above are correct. - ANSWER:b
*3) Which of the following statements about the taxonomic hierarchy is most accurate?
A) When considering the hierarchy from general to specific, family comes before order.
B) The emergent properties found at each level provide that level with an evolutionary advantage
over the previous level.
C) The genus and species names of an organism must be capitalized.
D) When considering the hierarchy from general to specific, phylum comes after order.
E) Although the hierarchy is a manmade system, it reflects the evolutionary history of the
organisms of the world. - ANSWER:e
6) Which of the following is a difference between allopatric and sympatric speciation?
A) Sympatric speciation requires genetic divergence to occur, but allopatric speciation does not.
B) Allopatric speciation is counteracted by geneflow between the groups, but sympatric
speciation is not.
C) Sympatric speciation occurs because of a physical separation between the groups, but
allopatric speciation does not.
D) Allopatric speciation is the least common of the two types.
, E) Sympatric speciation was thought to not be possible due to geneflow between groups. - ANSWER:e
7) Which of the following may act as a prezygotic isolation mechanism?
A) The great-horned owl displays courtship behaviors at night, and the closely related barn owl
does so during the evening.
B) One year-old common ground lizards do not mate because they are not sexually mature, but
two year-olds can mate.
C) Male red-winged blackbirds from different parts of the country sing different versions of the
species-typical song, which may not be recognized by females from various locations.
D) Two of the above are correct.
E) A, B, and C are correct. - ANSWER:d
*8) In an effort to maintain the genetic diversity of the seaside sparrows, scientists crossed the
near-extinct Dusky seaside sparrow with the Scott's seaside sparrow. What was the outcome of
this effort, as presented in class?
A) Genetic diversity was lost because scientists caused geneflow between 2 monophyletic
groups.
