Classification and Tree of Life
| Term | Definition |
|---|---|
| taxonomy | the science of describing, naming, and classifying organisms |
| taxon | any named taxonomic group of any rank in the hierarchical classification of organisms; for example: family, genus, or species |
| binomial nomenclature | a naming system that gives each organism a two-word scientific name consisting of the genus name followed by the species name |
| genus | the level of classification that comes after family and contains similar species |
| species | the level of classification that indicates the ability to produce fertile offspring between two organisms |
| phylogeny | the evolutionary history of species or taxonomic group |
| cladistics | a phylogenic classification system that uses shared derived characters and ancestry as the sole criterion for grouping taxa |
| cladogram | a diagram that is based on patters of shared derived traits and that shows evolutionary relationships between groups of organisms |
| derived character | a feature that evolved only within a particular taxonomic group |
| Bacteria | Taxonomic group that contains prokaryotes, extremely small, single-celled organisms that usually have a cell wall and that usually reproduce by cell division |
| Archaea | Taxonomic domain that contains prokaryotes (most of which are known to live in extreme environments) that are distinguished from other prokaryotes by differences in their cell walls |
| Eukarya | taxonomic domain that contains all eukaryotes in kingdoms Protista, Plantae, Fungi, and Animalia |
