• Gene Flow
• Genetic Drift

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.

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

The gradual change in a species over time is called

• mutation.
• evolution.
• migration.
• variation.

Which term refers to the process by which individuals that are better adapted to their environment are more likely to survive and reproduce?

• natural selection
• overproduction
• competition
• variation

Darwin concluded that organisms on the Galápagos Islands

• had changed over time.
• had remained the same.
• were the result of selective breeding.
• had no variations.
