Question:
Which of the following would be an example of convergent evolution?
1. Hummingbird bill sizes changing shape to fit easily into flowers
2. competition among finches of Galápagos Islands causing speciation
3. Anteaters in Australia and anteaters in South America both developing long, narrow skulls
4. Maple trees migrating northward after glaciers started to reced in North America
Answer:
S 3. Anteaters in Australia and anteaters in South America both developing long,
narrow skulls
Question:
natural selections based on all of the following EXCEPT which below?
1. An individual organism adapts to its environment and thus, evolve.
2. Genetic variation exists within population
3. The best adapted individuals tend to leave the most offspring
4. populations tend to produce more individuals than their environment can support
Answer:
S 1. An individual organism adapts to its environment and thus, evolve.
Question:
In the mid-1900s, a Soviet geneticist named Lysenko believed that one individual wheat plant,
when exposed to ever colder temperatures and then fertilized, would eventually start to produce
more cold tolerant offspring. Lysenko's hypothesis here was most in agreement with the ideas of:
1. Hutton
2. Lamarck
3. Darwin
Darwin's explain action of natural selection required long time spans (millions of years) in order
to modify populations. From where did Darwin first get the concept of the Earth's ancient age?
1. Charles Lyell
2. Catholic Church
,3. Alfred Wallace
4. Thomas Malthus
Answer:
S 1. Charles Lyell
Question:
Structures as different as human arms, bat wings, and dolphin flippers contain many of the same
bones and these bones have developed from very similar embryonic tissues. How do biologists
interpret here similarities?
1. by proposing that humans,bats and dolphins share a recent common ancestor
2. By identifying the bones as being analogous traits generated by different environments
3. by the principle of convergent evolution which produces similar traits
Answer:
S 1. by proposing that humans,bats and dolphins share a recent common
ancestor
Question:
In one river, fish called pike-cichlids are visual predators of smaller fish. The pike-cichlids locate
their prey by sight. If a population of the smaller fish experiences predation pressure from the
pike-cichlids, which of the following should least likely be observed in the smaller fish
1. Selection for nocturnal smaller fish
2. selection for males that attract females with bright coloration
3. selection for smaller fish that are faster swimmers
Answer:
S 2.selection
for males that attract females with bright coloration
Question:
Ichthyosaurs were ancient Asiatic reptiles. Fossils show us that they had dorsal fins and tails, like
fish do, even though their closest relatives were not aquatic, but instead land-dwelling reptiles
that didn't have dorsal fins nor tails. Thus, the dorsal fins and tails of ichthyosaurs and fish are:

1. Homologous
2. examples of convergent evolution
, 3. Adaptions to a common environment
4. divergent similarities
Answer:
S 2.examples of convergent evolution
Question:
3. Adaptions to a common environment
Evolution requires variation which can come from a random process called , but this
variation can be edited by the non-random portion of evolution called .
1. Mutation; natural selection
2. Mutation; artificial selection
3. Selection; environment
4. mutation;carnal selection
Answer:
S 1. Mutation;natural selection
Question:
Male peacock spiders have very colorful abdomens and perform elaborate dances to entice
mates. Because these colors provide no other benefit for the organism, they are likely the result
of what type of selection?
1. disruptive
2. Convergent
3. Artificial
4. Sexual
Answer:
S 4. Sexual
Question:
Over time, the movement of people around the earth has steadily increased. This has altered the
course of human evolution by increasing:
1. Genetic stability
2. Geographic isolation
3. genetic drift
