Natural Selection and Types of Natural Selection

Populations evolve to be better and better adapted to their specific environment because individuals with useful traits tend to survive longer and reproduce more. Over many generations this increases the frequency of these useful traits.

• Genetic drift

• Mutations

• Artificial Selection

• Natural Selection

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily
