- Binomial Naming System — a method of naming species using two terms, the genus and species. Example: Homo sapiens
- Three Domain System — a classification system that divides life into three domains: Archaea, Bacteria, and Eukaryota. Example: Archaea are primitive bacteria living in extreme environments.
