Across
  1. 2. Shows common ancestry through the similarities of embryos
  2. 3. AKA divergent evolution
  3. 4. Anatomical features that are present but no longer have a function
  4. 6. similar structures that evolved in distantly related species
  5. 8. Same Structure, Different Function
  6. 11. structure Different structure, same function
  7. 13. A hypothetical type of phylogenetic tree showing ancestry based of characteristics
  8. 14. Cycles of rapid species or long periods of little change in a population
  9. 15. AKA non-random mating, the competition for & selection of mates
Down
  1. 1. The distribution of related species based on geographic location
  2. 2. If a species cannot adapt quickly enough to a changing environment, it dies off
  3. 5. the formation of new species arising from a common ancestor
  4. 7. The purpose of a structure changes from its original function
  5. 9. The evolutionary history and record of common ancestry between species
  6. 10. Remains of an organism who has traits common to both its ancestors and its descendents
  7. 12. A widespread loss of biodiversity due to extreme ecosystem changes
