Vestigial Structures
Mutation
Structures that are inherited from ancestors but have lost all of their original function are called:

Based on the graphs, what percentage of the moth population is made up of light moth color morphs?
20%
50%
80%
100%
Using the information provided, predict what would happen to the percentage of dark moths if the environment changed to a darker forest. Explain your reasoning.
The percentage of dark moths would decrease because they would be more visible
The percentage of dark moths would stay the same because environment does not affect survival
The percentage of dark moths would increase because they could camouflage better
The percentage of dark moths would decrease because they would eat less food
Level 3 Applying Natural Selection: What is the most likely reason for the change in the moth population overtime?
The individual moths changed their color to help them survive.
The moths with the matching colors were more likely to survive and reproduce.
The moth behavior was influenced by the coal pollution in the forest.
The bird predators selected the moths based on taste.

Covers the eye and protects it while the frog is underwater
Detects sound waves
