, 1. A bacteriologist is studying two asexually reproducing strains of E. coli. The two
require different amounts of trace minerals for survival; on these grounds, the
bacteriologist determines that they are separate species. In making his
determination, he is using which species concept or concepts?
A) biological species concept
B) ecological species concept
C) morphospecies concept
D) phylogenetic species concept
E) None of the answer options is correct.
2. The figure below shows a ring species complex for seven populations of
salamander. The seven populations are arranged around a low valley that the
salamanders cannot cross.
Data from:
http://www-tc.pbs.org/wgbh/evolution/library/05/2/images/l_052_05_l.jpg
A) reinforcement.
B) pre-zygotic isolation.
C) post-zygotic isolation.
D) ecological isolation.
E) temporal isolation.

Which of the following statements BEST reflects the spread of alleles between
E.e. crocreatur and E.e. klauberi?
A) These two populations do not share any alleles because they are geographically
separated from one another.
B) These two populations share alleles, but alleles in E.e. crocreatur that are present in
E.e. klauberi arrived in that population by travelling through the “ring” of other
species.
C) These two subspecies probably arose through allopatric speciation when the valley
in the center divided an original population.
D) The original population probably covered the entire distribution shown in the
figure, but when the valley formed the different populations speciated.
4. A drawback of the biological species concept is that it CANNOT be applied to:
A) populations of a single species living in different places.
Page 2
, B) plants, which do not physically come in contact with each other when transferring
gametes the way that animals do.
C) highly polymorphic species.
D) extinct and asexual organisms.
E) All of these choices are correct.
5. Ring species such as the greenish warbler complicate the biological species
concept because:
A) at least some of their populations are reproductively isolated from one another but
can still exchange genetic material.
B) at least some of their populations overlap spatially, but individuals in those
populations do not interbreed with one another.
C) individuals in at least some populations interbreed with individuals from other
species.
D) ring species comprise populations that are in the process of allopatric speciation.
E) None of the other answer options is correct.
6. In some large groups of plants, including dandelions, oaks, and willows, the
biological species concept is complicated because the process of _____ allows
gene flow to occur between good _____ that can be easily distinguished based on
appearance.
A) hybridization; morphospecies
B) hybridization; ecological species
C) allopatric speciation; ring species
D) polyploidy; evolutionary species
E) polyploidy; ring species
7. Two individuals of opposite sex are members of the same species if they:
A) look similar.
B) similarly.
C) they share genetic information.
D) can produce fertile offspring.
8. Two populations are the same species if their members can potentially breed with
each other.
A) True
B) False
9. Unlike the biological species concept, the morphospecies concept relies on:
A) physiology.
B) phenotype.
