having a body part that has no known function

similar structures in more than one organism because they evolved from a common ancestor

similar structures that evolved independently in two living organisms to serve the same purpose

30.
Whales live in the ocean. They do not have legs, but they do have a pelvis with small leg bones attached to it. This is evidence that:
a)
Whales are not well adapted to ocean life.
b)
Whales do not have homologous structures
c)
Whales evolved from animals that once lived on land
d)
Whales evolved from some type of fish
31.
This fossil trilobite and this living blue crab both have a limb structure called a biramous limb. What best explains why both species have biramous limbs?
a)
It is impossible to say. Fossils are very old, so we cannot make observations of the trilobite’s ancestors, and we cannot explain its body structures.
b)
The trilobite and blue crab both share the same ancestor population that had a biramous limb. They inherited this structure from the ancestor population.
c)
All species have their own specific body structures, so it is a coincidence that this trilobite and blue crab each happen to have the biramous limb structure.
d)
The trilobite and blue crab are different species, so they must not share an ancestor population. They inherited their biramous limb structure from separate ancestor populations.
32.
Which of the following is NOT a vestigial structure?
a)
appendix
b)
lungs
c)
coccyx
d)
ear muscle
33.
This red kangaroo and this alpine newt both have a femur bone in their back limbs. However, their femur bones are very different. The red kangaroo has long femur bones that help it jump very far. The alpine newt has short femur bones that help it swim. What most likely explains why both have back limbs with a femur and why the femur bones are different?
a)
The red kangaroo and alpine newt are different species, so they do not share an ancestor population. These species had separate ancestor populations, and each evolved femur bones that help it survive in its environment.
b)
It is impossible to explain the structures of different species. The way that structures change over time is very complex, and no one has ever observed these changes occurring.
c)
The red kangaroo and alpine newt both inherited femur bones from a shared ancestor population, but this population separated into different environments. In each environment, different types of femur bone evolved, which helped the populations survive.
d)
All species have their own specific body structures, so it is a coincidence that the red kangaroo and alpine newt each happen to have femur bones that are different.
34.

a)
homologous structures
b)
vestigial structures
c)
water to land evolution
d)
analogous structures
35.
In a meadow, there are two colors of coneflowers: Pink and yellow. The bees and other pollinators seem to be more attracted to the pink flower and visit the pink flowers more often than the yellow flowers. Over time there are more pink flowers in the meadow than yellow. What principle is at work here?
a)
speciation
b)
environmental pressure
c)
natural selection
d)
homologous structures
36.
What evidence do similarities between fossil bones and modern organisms provide?
a)
species that face similar environmental pressure will develop similar traits.
b)
homologous structures are evidence that the two species are related or shared a common ancestor
c)
natural selection
d)
adaptive structures help organisms survive in their habitat
37.
This octopus and this fossil ammonite both have a body structure in their mouths called a radula. The radula is a structure used for eating. What best explains why both species have a radula?
a)
All species have their own specific body structures, so it is a coincidence that this octopus and ammonite each happen to have a radula structure.
b)
The octopus and ammonite both share the same ancestor population that had a radula. They inherited this structure from the ancestor population.
c)
It is impossible to say. Fossils are very old; therefore, we cannot make observations of the ammonite’s ancestors, and we cannot explain its body structures.
d)
The octopus and ammonite are different species, so they must not share an ancestor population. They must have inherited radulas from separate ancestor populations.
38.

a)
species change over time
