A fire has wiped out the vegetation that produces medium size seeds. As a result, the finches left can feed on seeds that are available in 2 sizes: small and large. What type of selection is likely to take place in this population?

• Disruptive Selection

• Artificial Selection

• Stabilizing Selection

• Directional Selection

What are structures that are similar in related organisms because they were inherited from a common ancestor.

• Analogous Structures

• Vestigial Structures

• Bone Structures

• Homologous Structures

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.
