  1. 3. Types of structures that indicate recent common ancestry
  2. 5. Hybrid breakdown is an example of this disruption to breeding
  3. 6. Sharing of alleles is interrupted before the zygote is formed
  4. 7. Change in allele frequencies due to random chance
  5. 8. Type of evolution where organisms evolve similar traits because of selective pressures (birds and butterflies with flight)
  6. 13. Type of lizard we watched a short film on for speciation
  7. 14. When a species splits into two or more species
  8. 16. Another name for speciation. Large scale changes above species level
  9. 17. Types of structures that evolved due to similar selective pressures but not necessarily a common ancestor
  10. 20. When reproduction between a species is interrupted by a geographic change
  11. 21. An organisms role in its environment
  12. 22. A way of testing to see if a population is evolving using math
Down
  1. 1. Rapid evolution of a species from a common ancestor sometimes after mass extinction
  2. 2. When organisms fight over the same resource
  3. 4. Change of allele frequency
  4. 9. Change over time
  5. 10. Differences in traits within a population
  6. 11. Structures that are remnants of an ancestral species (femur in whales)
  7. 12. Change in allele frequencies due to migration
  8. 15. The mechanism for evolution put forth by Charles Darwin
  9. 18. A way speciation can happen through changes in interbreeding in a species
  10. 19. Type of evolution where species share homologous structures and a recent common ancestor
