Evolution Review

What is the process in which populations CHANGE gradually over time?

• evolution

• species

• variation

• competition

What do you call SIMILAR structures that related species have inherited from a common ancestor?

• Natural Selection

• Analogous Structure

• Vestigial Structure

• Homologous Structure

What do you call a characteristic an organism was born with that helps the organism to survive in an environment?

• variation

• adaptation

• selection

• overproduction

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________

• Species
• Environmental Change
• Adaptation
• Variation

Genetic differences between organisms of the same species

• Variation
• Adaptation
• Behavior
• Environment

Remains of ancient organisms are called

• Extinctions
• Fossils
• Mutations
• Variations

Organisms produce more offspring than can survive

• Overproduction

• Variation

• Competition

• Survival of the Fittest

• Inheritance of Traits

All of the antelope are different. Some have longer legs and are faster than others.

• Overproduction

• Variation

• Competition

• Survival of the Fittest

• Inheritance of Traits

The sharks with the strongest tails swim the fastest and are able to catch the most prey.
