A change in beach color made medium-tan crabs the most visible to predators.
Natural selection is also known as survival of the (a) .
What is the most likely explanation of the data shown below?
There has been a drought in the area that is affecting all life forms.
The population of natural predators of the moths has gotten smaller.
The moths are living in an environment with light trees.

Why is the mouse population changing over time?
The light mice can reproduce more successfully than the dark mice.

Variation
Process by which organisms that are most suited to their environment survive and reproduce most successfully
Natural Selection
Change in populations over time; Process by which modern organisms have descended from common ancestors
Evolution
Heritable characteristic / trait that increases an organism's ability to survive and reproduce in its environment
Adaptation
How well an organism can survive and reproduce in its environment
Fitness
In artificial selection, nature provides the inherited variations, and (a) select those variants they find useful; In natural selection, (b) selects individuals with adaptations that are well suited to their environment (have high fitness).

Which best describes the role of mutations in natural selection?
Mutations help an organism to better survive in their environment
An organism may acquire a helpful mutation by interacting with the environment
A mutation may result in a beneficial trait that makes an organism more likely to survive and reproduce
Organisms with certain traits are more likely to win competitions for mutations
