| 12616348318 | Systematics | A scientific discipline focused on classifying organisms and determining their evolutionary relationships. | 1 | |
| 12616348319 | Phylogenetic tree | A family tree that shows the evolutionary relationships thought to exist among groups of organisms | 2 | |
| 12616348320 | Taxonomy | The scientific study of how living things are classified and ordered | 3 | |
| 12616399697 | Binomial | The two-part latinized name of a species, consisting of the genus and specific epithet. | 4 | |
| 12616403406 | Genus | A classification grouping that consists of a number of similar, closely related species. First part of a binomial name. | 5 | |
| 12616513460 | family | Group of genera that share many characteristics | 6 | |
| 12616514398 | Orders | Group of similar families | 7 | |
| 12616516735 | Classes | Group of similar orders | 8 | |
| 12616521415 | Phyla | Group of similar classes | 9 | |
| 12616522506 | Kingdoms | Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia | 10 | |
| 12616523494 | Domains | Bacteria, Archaea, Eukarya | 11 | |
| 12616526354 | DKPCOFGS | Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species; levels of classification | 12 | |
| 12616577937 | Taxon | named group of organisms, such as a phylum, genus, or species | 13 | |
| 12616714042 | Branch points | the representation on a phylogenetic tree of the divergence of two or more taxa from a common ancestor | 14 | |
| 12616719991 | Sister taxa | Groups of organisms that share an immediate common ancestor and hence are each other's closest relatives. | 15 | |
| 12616727596 | Rooted | a branch point within the tree represents the most recent common ancestor of all taxa in the tree; shown at the far left of the tree. | 16 | |
| 12616765155 | basal taxon | diverges early in the history of a group and originates near the common ancestor of the group; far related to the rest of the organizations on a tree | 17 | |
| 12616769495 | Polytomy | a branch point from which more than two descendant groups emerge | 18 | |
| 12616826519 | What three points can a phylogenetic tree make? | Patterns of descent, over phenotypic similarity. The branches of the tree don't show age unless it says it does. Taxons next to each other (sister taxons) did not necessarily evolve from each other. | 19 | |
| 12617046770 | Analogy | Two things that are similar due to convergent evolution, not a common ancestor | 20 | |
| 12617078434 | Homoplasies | Analogous structures that have evolved independently. | 21 | |
| 12617116276 | Molecular systematics | A scientific discipline that uses nucleic acids or other molecules in different species to infer evolutionary relationships. | 22 | |
| 12617131122 | Cladistics | A phylogenetic classification system that uses shared derived characters and ancestry as the sole criterion for grouping taxa. | 23 | |
| 12617134846 | Clade | A group of species that includes an ancester species and a l l of its descendants. | 24 | |
| 12617144961 | Monophyletic | Pertaining to a taxon derived from a single ancestral species that gave rise to no species in any other taxa. (A clade0 | 25 | |
| 12617154068 | Paraphyletic | Pertaining to a group of taxa that consists of a common ancestor and some, but not all, of its descendants. | 26 | |
| 12617167156 | Polyphyletic | pertaining to a group of taxa derived from two or more different ancestors | 27 | |
| 12617186194 | shared ancestral character | A character, shared by members of a particular clade, that originated in an ancestor that is not a member of that clade. | 28 | |
| 12617187068 | shared derived character | An evolutionary novelty that is unique to a particular clade, not seen in ancestors outside of the clade. | 29 | |
| 12617209742 | outgroup | A species or group of species that is closely related to the group of species being studied, but clearly not as closely related as any study-group members are to each other; don't have the traits they are looking at. | 30 | |
| 12617212105 | ingroup | A species or group of species whose evolutionary relationships we seek to determine. | 31 | |
| 12617254003 | Maximum Parsimony | A principle that states that when considering multiple explanations for an observation, one should first investigate the simplest explanation that is consistent with the facts. | 32 | |
| 12617461534 | Molecular Clock | Model that uses DNA comparisons to estimate the length of time that two species have been evolving independently | 33 | |
| 12617572930 | Horizontal Gene Transfer | The transfer of genes from one genome to another through mechanisms such as transposable elements, plasmid exchange, viral activity, and perhaps fusions of different organisms. | 34 |
