- 14. The evolutionary history and relationships of a group of organisms.
- 15. The point on a cladogram where a single lineage splits into two.
- 16. segment of a cladogram that leads to a specific taxon (species or group) existing at the "tips" of the diagram.

- 19. The organizational system of grouping taxa from most general to most specific.
Down
- 1. The plant family that was famously reclassified using cladistics.
- 3. Traits that are similar because they were inherited from a common ancestor.
- 4. The domain that includes all organisms with membrane-bound organelles.
- 5. Any unit used in biological classification, such as phylum or class.
- 6. The process of moving a species to a new taxon based on new genomic evidence.
- 9. The process where unrelated species evolve similar traits.
- 11. The science of classifying and naming organisms.
- 12. A group of organisms that evolved from a common ancestor.
- 13. Traits that are similar due to convergent evolution rather than shared ancestry.
- 17. The order of nucleotides or amino acids used to determine clades.
