When differences in traits are related to chances of survival, they are said to be under

A. Osmosis

B. Convergent Evolution

C. Natural Selection

D. Transcription

Brown anole lizards are useful for studies of natural selection because

A. They are abundant

B. Easy to catch

C. Have a short lifespan

D. All of above

What is a significant force of natural selection (or the selective pressure) on brown anole hatchlings?

A. Predators

B. Humans

C. Traffic

D. Pollution

Why are smaller hatchlings more likely to die?

A. They are more likely to be stepped on by humans

B. They are more likely to be eaten

C. They are more likely to be run over by cars

Juvenile anoles that get eaten by predators will not survive and reproduce.

A. True

B. False

Aaron and Robert observed thousands of lizards on the island. What did they predict about the size of lizards and survival?

A. Smaller lizards are less likely to survive

B. Larger lizards are less likely to survive

According to the graph, lizards with a body lenght under 22 mm have a survival rate

A. Lower than 50%

B. Higher than 50%

According to the graph, lizards with a body lenght over 26 mm have a survival rate

A. Lower than 50%

B. Higher than 50%

What body lenght has the highest survial rate?

A. 22 mm

B. 28 mm

C. 31 mm

D. 32 mm

Lizards that are over 32 mm do not survive as well as lizards that are medium sized because the large lizards are easy for predators to see. Lizards that are too small are easily caught. As a result most lizards are medium sized. What type of natural selection is this?

A. Directional

B. Stabilizing

C. Disruptive
