  1. 2. Type of evolution that results in homologous structures.
  2. 5. Same function but different arrangement.
  3. 8. Different function but similar arrangement.
  4. 9. Supercontinent that existed millions of years ago.
  5. 11. Mutations develop over generations to create new genetic variations that become new species.
  6. 12. Type of evolution that results in analogous structures.
  7. 13. Helps place important events and species in the appropriate era and show changes over time.
  8. 14. Change in a gene(Helpful, Harmful, Neutral)

  1. 1. Study of early features and development.
  2. 2. Closely related organisms have similar structures because of similar amino acids.
  3. 3. Layer in the fossil record with younger samples.
  4. 4. Layer in the fossil record with older samples.
  5. 6. Assumed in organisms with very similar DNA strands.
  6. 7. Populations of same species living in different places become increasingly different as they adapt to environment.
  7. 10. No function but still exist in the body.
