| Dichotomous Key | A tool used to classify an organism through a series of questions with only two possible answers |
| Ancestry | The lineage of successive parents and offspring that leads to an organism or species |
| Cladistics | A classification system based on shared characteristics between groups of organisms and their common ancestor |
