• adaptation

• natural selection

• evolution

• mutation

One of Darwin's most important observations was the differences in beak shapes of the Galapagos finches. He concluded that:

• these finches evolved from one species of finch

• these finches were not related

• finches remain unchanged since the beginning of time

What might happen to this population? Infer or predict the traits of future generations.

• There will be more green beetles in the population.

• There will be more brown beetles in the population.

• There will be an equal amount of brown and green beetles in the population.

• None of these, since body color is not passed on.

There are genetic differences in beetles, like body color. This is known as a:

• mutation

• adaptation

• selection

• variation

Many organisms have structural adaptations to help them survive. Which structural adaptation does this picture show?

• Mimicry
• Mouth Shape
• Body Shape
• Camouflage

These birds are all from the same species; however, they have slight differences in their beak shape. What term would we use to describe these differences?

• Camouflage
• Adaptations
• Variations
• Selective Breeding

Animals use different types of adaptations to help them survive. What type of adaptation is this: "The jackrabbit stays still during the hottest part of the day, helping it conserve energy."

• Behavioral
• Structural
• Functional
