4.

Suppose that certain individuals in a population of carnivores (ex. owls) become better at hunting prey (ex. mice). Because of genetic variation, certain individuals of the prey have traits that allow them to escape or hide from their predators, and they pass these traits on to their offspring. However, a few individuals in the predator population also may have traits (ex. better eyesight or quicker reflexes) that allow them to hunt the better-adapted prey successfully. Thus, passing these traits on to their offspring. This scenario is an example of which of the following processes?
- A.
  
  Coevolution
- B.
  
  Directional natural selection
- C.
  
  Microevolution
- D.
  
  Stabilizing natural selection
