1
Changes in organisms over a long period of time, including the rise of novel organisms and extinction, is known as
A)natural selection.
B)microevolution.
C)macroevolution.
D)punctuated equilibrium.
2
One of the major sources of evidence for evolution is in the comparative anatomy of organisms. Features that have a similar look but different structural origin are called
A)homologous structures.
B)analogous structures.
C)vestigial structures.
D)equivalent structures.
3
Homologous structures in organisms are the result of
A)divergence.
B)convergent evolution.
C)stasis.
D)ontogeny.
4
The Hardy-Weinberg equilibrium allows scientists to study
A)natural selection.
B)microevolution.
C)macroevolution.
D)punctuated equilibrium.
5
A large set of organisms lives in a large, stable ecosystem that has an adequate carrying capacity. There is no competition for resources. Individuals mate at random. All organisms appear to be identical except for a few individuals in the most recent generation of offspring that exhibit a different fur coat color and pattern. The ecosystem and population are geographically isolated from other populations of the same organism. Which Hardy Weinberg assumption has been violated?
A)large population size.
B)random mating within the population.
C)no mutation within the population.
D)no input of new alleles or loss of alleles.
6
A population of 1000 individuals has 200 individuals who show a homozygous recessive phenotype and 800 individuals who express the dominant phenotype. What is the frequency of homozygous dominant individuals (p2) in this population?
A)p2 = 0.20
B)p2 = 0.30
C)p2 = 0.45
D)p2 = 0.55
7
A chance event that causes a population to lose some individuals (they died), and hence a loss of alleles to the population, results in
A)mutation.
B)migration.
C)selection.
D)genetic drift.
8
Selection that causes an extreme phenotype to be more frequent in a population is an example of
A)disruptive selection.
B)stabilizing selection.
C)directional selection.
D)equivalent selection.
9
A key element of Ernst Mayr's biological species is
A)homologous isolation.
B)divergent isolation.
C)convergent isolation.
D)reproductive isolation.
10
Sympatric species are populations of species that live in the same habitat. Sympatric species of deer mice (Peromyscus sp.) are externally identical. However, the males of different species have a differently shaped baculum or bone found in the penis. This is an example of which type of reproductive isolation?
A)temporal
B)mechanical
C)behavioral
D)ecological
