• fossilization

• natural selection

• variation

Over time, the organisms that are "fittest" will survive and reproduce, passing on the more favorable genes for a specific environment. What is this process called?

• adaptation

• extinction

• specialization

Imagine this is the most common color pattern for anoles on an island. Then an insect pest wipes out the normal species of trees and a new species of tree with much darker bark replaces it. What is likely to happen to the population of anoles on this island over time?

• the anoles' current color pattern will continue to be the most common one after many generations

• the anoles will develop webbed feet over many generations for swimming

• the anoles' color pattern will change randomly to some new color after many generations

• the anoles' color pattern will shift over many generations to a darker pattern being the most common
