• Adaptation

• Behavior

• Environment

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

• Dark moth

• Light moth

• Both will be equally successful

• Neither will be successful

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

A German Shepard would probably not survive in the wild because...

• the dog is mixed.
• the dog is a product of artificial selection and not adapted for the wild.
• the dog is dumb.
• the dog is a product of natural selection and can survive in the wild.
