Change Over Time

• A species is a group of organisms that are closely related and can mate to produce fertile offspring.

• Adaptations are characteristics that improve an individual’s ability to survive and reproduce in an environment.

• Adaptations are how species respond to their environment.

Multiple Choice

What can help explain how a population responds to its environment?

• Evolution

• Adaptation

• Seperation

• Division

Multiple Choice

What is a group of organisms that are closely related and can mate to produce fertile offspring?

• species

• fossil

• mold

• cast

Traits and Evolution

• A species that has adapted has a better chance to survive than a species that has not.

• Genetically determined characteristics are called traits.

• Over time a species will inherit new characteristics (traits) and become a new species. This is called evolution.

Multiple Choice

What is the process in which inherited characteristics change over time resulting in the formation of a new species?

• Adaptation

• Evolution

• Seperation

• Division
