Why do woodpeckers have long beaks to dig into trees for insects?

• As insects became more common, birds that ate more insects grew longer beaks.

• The long beak is an adaptation that helps the bird eat more insects.

• A harmful mutation occured.

• The long beak helps woodpeckers fight off predators.

Many animals who live where it snows have fur. Explain how white fur makes surviving in the snowy environment easier.

• Orange fur make them easier to spot.

• White fur allows them to better blend in with their habitat.

• The color of fur doesn't effect an animals chance of survival.

• White fur is cooler then other fur colors.

Explain how the fossil record is evidence for the scientific theory of evolution.

• It proves what future species of animals will look like in the future.

• It shows that extinct animal have become a fossil through selection.

• It shows that extinct species share similarities with current species.

• It allows scientist to compare fossils from the past to undiscovered fossils.

The pictures are from different types of animals. What can be said about them that is true?

• They all have different bones, which implies that they all share a different ancestor.

• They all have different bones, which implies that they all share a common ancestor.

• They all have similar bones, which implies that they all share a different ancestor.

• They all have similar bones, which implies that they all share a common ancestor.
