temporally
D
behaviorally
3

Which of the following must occur for speciation to happen?

A
geographic isolation
B
reproductive isolation
C
temporal isolation
D

Darwin hypothesized that new species could appear gradually through small changes in an ancestral species. What experiment did he conduct to test this hypothesis?

A
the breeding of finches
B
the breeding of pigeons
C
the observation of humans
D
the observation of dog breeds
5

Why do species evolve during adaptive radiation?

A
to fill different niches
B
to create variation
C
to become reproductively isolated
D
to provide evidence of evolution

Two species of flies, Drosophila melanogaster and Drosophila simulans, can mate. They usually do not mate, however, even if they are kept together in a laboratory. Males court the females of both species, but the females prefer to mate with males of their own species. Which isolating mechanism does this describe?

A
behavioral
B
temporal
C
artificial
D
anatomical
7

Which of the following is the best definition of biogeographic isolation?

A
the separation of members of a species through geographical or biological forces
B
the separation of members of different species through geographical forces
C
the separation of populations of different species through time
D
the separation of members of a species through anatomical forces
8

Which is most likely to happen to a population that becomes anatomically isolated from the rest of its species?

A
The entire species will become extinct.
B
The population will become a separate species over time.
C
The population will breed with a different species nearby.
D
The entire species will continue to have viable offspring together.

Cardueline finches can be found in many areas of the world, including North America and Asia. Hawaiian honeycreepers, which are found only in Hawaii, have been found to have DNA commonalities with this group of finches that indicate they have a common ancestor. Which mechanism might have led to the appearance of the Hawaiian honeycreeper?

A
anatomical isolation
B
temporal isolation
C
geographical isolation
D
behavioral isolation
10

Which lists the correct sequence of events for evolution to occur through isolation?

A
founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results
B
genetic changes occur, founding population arrives, reproductive isolation results, biogeographic isolation occurs
C
biogeographic isolation occurs, founding population arrives, genetic changes occur, reproductive isolation results
D
founding population arrives, genetic changes occur, biogeographic isolation occurs, reproductive isolation results
