Green anoles are lizards that can change their skin color rapidly in response to various stimuli. This adaptation is the result of —

• selective breeding of lizards by humans

• beneficial traits passed from parents to offspring

• geographic isolation that prevented genetic mutation

• environmental pollutants that changed their genotype

Leaf-cutter ants harvest leaves and carry them to fungi that convert plant material into a usable form for the ants to digest. The fungi depend on the leaves for nutrients. The ants also produce an antibiotic on their bodies that helps protect the fungi from harmful bacteria.

What is the relationship between the leaf-cutter ants and the fungi?

Why is it important to assign each organism a scientific name?

Two scientists studied patterns of evolution in the fossil record. Many species they analyzed showed periods of slow changes interrupted by a period of rapid change.

This pattern of periods of slow change interrupted by periods of rapid change with few, if any transitional fossils, best describes the theory of —

• natural selection

• genetic drift

• gene flow

• punctuated equilibrium
