  1. 2. Type of evolution that results in homologous structures.
  2. 5. Layer in the fossil record with younger samples.
  3. 7. Change in a gene(Helpful, Harmful, Neutral)
  4. 9. Layer in the fossil record with older samples.
  5. 10. Supercontinent that existed millions of years ago.
  6. 11. Study of early features and development.
  7. 12. Same function but different arrangement.
  8. 13. No function but still exist in the body.
  9. 14. Populations of same species living in different places become increasingly different as they adapt to environment.

  1. 1. Type of evolution that results in analogous structures.
  2. 2. Closely related organisms have similar structures because of similar amino acids.
  3. 3. Mutations develop over generations to create new genetic variations that become new species.
  4. 4. Helps place important events and species in the appropriate era and show changes over time.
  5. 6. Different function but similar arrangement.
  6. 8. Assumed in organisms with very similar DNA strands.
