Evolution

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Change over time

• Natural Selection
• Selective Breeding
• Homeostasis
• Evolution

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
• evolution

Whales are aquatic mammals that contain a pelvis (hip) bone. Even though it does not aid in its movement, the function must have been used by a common ancestor of the whale. Thus, the pelvis is referred to as a(n)

• vestigial structure

• analogous structure

• homologous structure

Genetic differences between organisms of the same species

• Variation
• Adaptation
• Behavior
• Environment

An error in DNA copying that results in a new trait

• Homeostasis
• Mutation
• Natural Selection
• Selective Breeding

A physical or behavioral trait that helps an organism survive and reproduce in its environment is called a what?

• An adaptation

• A response to a stimulus

• A mutation

• Evolution

Genetic diversity is decreased through this process.

• Gene Flow

• Genetic Drift
