How is it possible that there are no fossilized skeletal systems found on the bottom layers of rock?
a) Volcanic activity and earthquakes destroyed the fossilized skeletal systems.
b) Organisms with skeletal systems were consumed by other animals.
c) Fossilized skeletons are crushed and destroyed by layers of heavy rock.
d) Organisms with skeletal systems did not exist when these layers of rock formed.

If you found a rock outside and wanted to know if it’s older than other fossils found in the same area, which of these should you use?
a) type and order of the rock layers
b) local weather conditions
c) a dictionary
d) water sample from a nearby lake

If you found a rock outside and wanted to know if it’s older than other fossils found in the same area, which of these should you use?

b) the fossil record
c) local weather conditions
d) a dictionary

If you found a fossil outside and wanted to know which currently living animal is its closest relative. Which of these statements will be most helpful in answering his question?
a) Differences in anatomical structures indicate evolutionary relationships
b) Organisms that share a pattern of common features are likely to be closely related.
c) Organisms that live in the same environment are closely related.
d) Common functions of appendages, like wings of a bat and bird, indicate a close relationship.

Which of these structures is the strongest evidence of an evolutionary relationship?
a) bat wing and bee wing
b) . bat lower jaw and whale lower jaw
c) whale flipper and bee wing

Over time, as the environment changes, populations must adapt or become extinct. Which example below explains how a population adapts to environmental changes?
a) As their environment changed, horses became larger and better adapted to running.
b) Horses feet changed from a single toe (hoof) to many toes.
c) Some dinosaur species became larger, becoming more elephant-like
d) They don't pass on their favorable traits.

Some woodpeckers in Maryland have learned to peck the wood on the sides of houses to find termites and bees nesting in people’s home. This is an example of a:
a) Behavioral adaptation
b) Structural adaptation
c) Physical adaptation
d) Physiological adaptation

A deer uses the color of his fur to hide himself from predators that may eat him. His fur color is an example of
a) A structural adaptation called hiding
b) A behavioral adaptation called hiding
c) a structural adaptation called camouflage
d) A behavioral adaptation called camouflage

What is the most likely explanation for the change in color within the mice population over time?
a) The mice had to change colors from light to dark in order to hide from predators
b) The pollution caused the mice to change color similar to the way the trees changed color
c) The birds did not like the taste of the darker colored mice and began to eat only the lighter colored mice
d) Dark mice were harder for predators to find so their populations increased and the population of the lighter mice decreased

Male birds who are more successful at the courtship behavior will have a greater chance of having more offspring. This behavior is the result of:
a) natural selection
b) genetic engineering
c) asexual reproduction
d) gene manipulation
