| Question | Answer |
|---|---|
| Taxonomy | the science of describing, naming, and classifying organisms. |
| Binomial Nomenclature | a system for giving each organism a two-word sceintific name that conists of the genus name followed by species names. |
| Genus | the level of classifaction that comes after family and contains similar species. |
| Family | the taxonomic category below the order and above the genus. |
| Order | the taxonomic category below the class and above the family. |
| Clas | the taxonomic category containing orders with common characterstics. |
| Phylum | the taxonomic group below kingdom and above class. |
| Kingdom | the highs=est taxonomic category, which contains a group of similar phyla. |
| Domain | a group of similar kingdoms. |
| Biological Species | a group of organisms that can reproduce only among themselves and that are usaully contained in a geographic region. |
| Phyloggeny | the evolutionary history of a species or taxonomic group. |
| Convergent Evolution | the process by which unrelated species become more siml=ilar as they adapt to the same kind of enviroment. |
| Analogous Character | similarities that arise through convergent evolution. |
| Cladistics | a phylogenetic classification system that uses shared derived characters and ancestry as the sole sole criterion for grouping taxa. |
| Ancestral Character | with respect of two different groups. |
| Derived Character | envolved in an ancestor of one group and not the other group. |
| Cladogram | a branching diagram constructed of cladistics that biologist use. |
| Evolutionary Systematics | taxonomists give varting degrees of importance to characters and thus produce a subjective analysis of evolutionary relationships. |
| Phylogenetic Trees | the analysis that displays the evolutionary realationships,also a branching diagram. |
