Insect wings and bird wings serve a similar function but are structurally different. This is an example of...
homologous structures
analagous structures
vestigial structures
disruptive selection
many animals have humerus, radius, and ulna bones because their common ancestor had those bones. This is an example of...
homologous structures
analogous structures
vestigial structures
disruptive selection
Which seed is best adapted for long-distance wind dispersal?
milkweed
maple
burdock
none of them
Which of these flower adaptations would be most successful for the survival of a species?
spiny seeds for better wind dispersal
different flowering times for better seed dispersal
sticky pollen for better water dispersal
specific odors for better insect pollination
Adaptive radiation is best described as...
unrelated organisms developing similar structures due to similar environmental pressures
when organisms change via habitual use and disuse of certain traits
multiple species evolving from one common ancestor
populations that are isolated from one another develop different traits
Which is an example of natural selection?
Selective breeding of tail-less cats
Giraffes stretching their necks to reach higher leaves
Juvenile birds learning to sing
Dark colored moths being less predated in dark colored forests
Leopard frogs and Green frogs have very distinct calls, which prevents interbreeding. This is an example of...
pre-zygotic reproductive barrier
post-zygotic reproductive barrier
natural selection
competition
Lions and Tigers can produce hybrid offspring called Ligers, however Ligers are infertile and cannot produce offspring of their own. This is an example of...
Pre-Zygotic Reproductive Barrier
Post-Zygotic Reproductive Barrier
Natural Selection
Competition
A group of lizards migrates across a landbridge from mainland to an island. The landbridge is eventually covered by water. What might we expect to happen as a result of this isolation?
The island population may diverge and develop new traits in response to their environment
The two populations will remain the same
The island population will find a way to get back to the mainland
The island population will diverge genetically, but not anatomically
Which best defines the principle of biogeography?
the study of different biomes
the study of migration patterns of animals
the distribution of different biomes across the globe
the distribution of life forms over geographical areas
How can scientists use DNA to determine evolutionary relationships?
Scientists can compare sequences between organisms, if the organisms are closely related they would expect the sequences to be similar
Scientists can compare sequences between organisms, if the organisms are closely related they would expect the sequences to be different
Scientists can compare sequences between organisms, if the organisms are distantly related they would expect the sequences to be similar
Scientists do not use DNA to determine evolutionary relationships
Which term best fits the definition "the movement of alleles between populations"

genetic drift
gene flow
allopatric speciation
sympatric speciation
Which term best fits the definition "divergence in the same geographic region, triggered by behavioral or reproductive isolation"
genetic drift
gene flow
allopatric speciation
sympatric speciation
Which type of selection is best described as "when an intermediate phenotype is favored over extremes"
stabilizing selection

disruptive selection
Which type of selection is best described as "only one extreme phenotype is favored over another"
stabilizing selection
directional selection
disruptive selection
TRUE or FALSE: Only phyletic gradualism is supported by the fossil record, not punctuated equilibrium
TRUE
FALSE
