| 408877289 | Phylogeny | The evolutionary history of a species or group of related species. | |
| 408877290 | Systematics | A scientific discipline focused on classifying organisms and determining their evolutionary relationships. | |
| 408877291 | Taxonomy | The ordered division and naming of organisms. | |
| 408877292 | Hierarchical Classification | the organization of objects into classes and subclasses on the basis of similarities and differences | |
| 408877293 | Binomial | The two-part, latinized format for naming a species. First part is the genus, second part is the species. First letter is capitalized and whole thing is italicized. | |
| 408877294 | Linnaean System | A classification system useful for storing and finding information about living things. Kingdom, Phylum, Class, Order, Family, Genus, Species | |
| 408877295 | Phylogenetic Tree | A branching diagram that represents a hypothesis about the evolutionary history of a group of organisms. | |
| 408877296 | PhyloCode | Proposed system of classification of organisms based on evolutionary relationship: Only groups that include a common ancestor and all of its descendants are named. | |
| 408877297 | Branch point | each branch point on a Phylogenetic Tree represents the divergence of 2 species. | |
| 408877298 | Sister Taxa | animals that closely resemble each other, have a lot in common, share an immediate common ancestor. | |
| 408877299 | Rooted Phylogenetic Tree | includes a branch to represent the last common ancestor of all taxa in the tree. | |
| 408877300 | Basal Taxon | In a specified group of organisms, a taxon whose evolutionary lineage diverged early in the history of the group. | |
| 408877301 | Polytomy | In a phylogenetic tree, a branch point from which more than two descendant taxa emerge. A polytomy indicates that the evolutionary relationships between the descendant taxa are not yet clear. | |
| 408877302 | Limitations of Phylogenetic Trees | 1. show patterns of decent not phenotypic similarities 2. Phylogenetic Trees don't indicate when a species evolved. no dates. 3. It shouldn't be assumed that a taxon evolved from the taxon next to it. | |
| 408877303 | Homology | Phenotypic and genetic similarities due to shared ancestry.Smilarity due to shared ancestry. Ex. Mouse and Rat. | |
| 408877304 | Analogy | Similarity between two species that is due to convergent evolution. Similarities due to adaptation/evolution. | |
| 408877305 | Homoplasy | Analogous structures or molecular sequences that evolved independently. | |
| 408877306 | Molecular Systematics | Uses DNA and other molecular data to determine evolutionary relationships. | |
| 408877307 | Cladistics | An approach to systematics in which organisms are placed into groups called clades based primarily on common descent. | |
| 408877308 | Bacteria | One of two prokaryotic domains, the other being Archaea | |
| 408877309 | Cladistics | Branch of science that groups organisms by common descent | |
| 408877310 | Clade | A group of species that includes an ancestral species and all of its descendants. | |
| 408877311 | Monophyletic | A clade that consists of the ancestor species and all its descendants. When A,B,C all share the same ancestor. | |
| 408877312 | Polyphyletic | When a clade has a different ancestor. A,B, C all hare the same ancestor but D has a different ancestor. | |
| 408877313 | Shared ancestral Character | a character that originated in an ancestor of the taxon | |
| 408877314 | Shared derived character | is an evolutionary novelty unique to a particular clade. | |
| 408877315 | Outgroup | A group that has diverged before the in-group. Its members are closely related to the group of species being studied, but not as closely related as any study-group members are to each other. | |
| 408877316 | Ingroup | A species or group of species whose evolutionary relationships we seed to determine |
