1.
It has been observed that organisms on islands are different from, but closely related to, similar forms found on the nearest continent. This is taken as evidence that ...
a)
island forms are descended from mainland forms.
b)
common environments are inhabited by the same organisms.
c)
island forms and mainland forms have identical gene pools.
d)
the island forms and mainland forms are converging.
2.
Given what we know about evolutionary biology, we expect to find the largest number of endemic species in which of the following geological features, which have existed for at least a few million years?
a)
an isolated ocean island in the tropics
b)
an extensive mountain range
c)
a grassland in the center of a large continent, with extreme climatic conditions
d)
a shallow estuary on a warm water coast
3.
The greatest number of endemic species is expected in environments that are ...
a)
easily reached and ecologically diverse.
b)
isolated and show little ecological diversity.
c)
isolated and ecologically diverse.
d)
easily reached and show little ecological diversity.
4.
Which of the following is the most predictable outcome of increased gene flow between two populations?
a)
lower average fitness in both populations
b)
higher average fitness in both populations
c)
increased genetic difference between the two populations
d)
decreased genetic difference between the two populations
5.
Currently, the only predators of Galapagos marine iguanas are Galapagos hawks. Iguana body size is not correlated with the risk of hawk predation, although small iguanas can sprint faster than large iguanas. If predators (i.e., cats) that preferably catch and eat slower iguanas are introduced to the island, iguana body size is like to ____ in the absence of other factors; the iguanas would be under ___ selection.
a)
increase; directional
b)
increase; disruptive
c)
decrease; directional
d)
decrease; disruptive

genetic drift
8.
You are confronted with a box of preserved grasshoppers of various species that are new to science and have not been described. Your assignment is to separate them into species. There is no accompanying information as to where or when they were collected. Which species concept will you have to use?
a)
biological
b)
phylogenetic
c)
ecological
d)
morphological
9.
Dog breeders maintain the purity of breeds by keeping dogs of different breeds apart when they are fertile. This kind of isolation is most similar to which of the following reproductive isolating mechanisms?
a)
temporal isolation
b)
behavioral isolation
c)
habitat isolation
d)
gametic isolation
10.
According to the concept of punctuated equilibrium, the "sudden" appearance of a new species in the fossil record means that...
a)
the species is now extinct.
b)
speciation occurred in one generation.
c)
speciation occurred rapidly in geologic time.
d)
the species will consequently have a relatively short existence, compared to that with other species.
11.
According to the concept of punctuated equilibrium,
a)
natural selection is unimportant as a mechanism of evolution.
b)
given enough time, most existing species will gradually give rise to new species.
c)
a new species accumulates most of its unique features as it comes into existence.

13.
If an organism has a relatively large number of Hox genes in its genome, it most likely...
a)
has Hox genes expressed in all cells of its body.
b)
has multiple paired appendages along the length of its body.
c)
has a relatively complex anatomy.
14.
If the complex protein assemblage of the prokaryotic flagellum arose by the same general processes of the complex eyes of molluscs (such as squids and octopi), then ...
a)
natural selection cannot account for the rise of the prokaryotic flagellum.
b)
ancestral versions of this protein assemblage were either less functional or had different functions than modern prokaryotic flagella.
c)
neither eyes nor flagella could have arisen by evolution because both are too complex to have evolved.
d)
the need for more complex structure must have driven evolution.

c)
fossil discovery techniques.
d)
