On the Galapagos Islands, different finches evolved on different islands to fit their environment. When a species develops unique traits because it is trapped in one area this is called:

A species lives in a particular environment.  What is TRUE about the environment that the species lives in and about how the species will look over thousands of years?

• The environment will stay the same, and the traits of the species will stay the same.
• There will be changes to the environment, but the traits of the species will stay the same.
• There will be changes to the environment that could lead to changes in the traits of the species.
• There will be changes to the environment, and the traits of the species will change, but the changes in the environment could never lead to changes in the traits of species.

Why did the population of peppered moths in England change from light to dark after the Industrial Revolution?

In recent years "SuperBugs" (bacteria that aren't effected by antibiotics) are becoming more and more common. How could natural selection explain this?

• Superbugs survive antibiotics and reproduce
• Antibiotics cause bacteria to become superbugs
• We have always had the same amount of superbugs; modern media just discusses them more.
• There is no reliable data on the origin of super bugs.
