Natural Selection

This makes an organism more suited to its environment

• species

• lifespan

• adaptation

• mutation

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution

• Natural Selection

• Extinction

• Artifical Selection

Which organisms are most likely to survive?

• the best adapted

• the fastest

• the strongest

• the most domesticated (tamed)

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

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection

• Variation

• Homeostasis

• Extinction

According to the graph, what happened to the moths over time?

• The dark-colored moth population increased while the light-colored moth population decreased

• The dark-colored moth population decreased while the light-colored moth population increase

• Both populations increased

• Both populations decreased

According to natural selection, organisms more suited to their environment are better able to

• Sleep

• Survive

• Perish

• Migrate
