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.
