| 1214863345 | phylogenetic tree | a branching diagram showing inferred evolutionary relationships among various species based on similarities and differences in characteristics | |
| 1214863346 | 1. morphological data: cell wall, early embryo stage 2. biochemical data: enzymes 3. molecular data: DNA sequences | To construct a tree, you need what three things? | |
| 1214863347 | taxon | represents each species which are put in a tree | |
| 1214863348 | sister taxa | species that are most closely related to each other | |
| 1214863349 | branch point | where lineages diverge | |
| 1214863350 | polytomy | an unresolved pattern of divergence | |
| 1214863351 | basal taxon | the lineage that branch off early, first of the tree out of the whole group | |
| 1214863352 | monophyletic group | consists of ancestral species and all of its descendants | |
| 1214863353 | paraphyletic group | consists of an ancestral species and some, not all, of its descendants | |
| 1214863354 | polyphyletic group | consists of taxa with different ancestors | |
| 1214863355 | outgroup | a species or group that is or are closely related to the ingroup | |
| 1214863356 | ingroup | various species being studied | |
| 1214863357 | archaea, bacteria, eukarya | Name the three domains | |
| 1214863358 | eubacteria, archaebacteria, fungi, plantae, animalia | Name the six kingdoms |
