- Taxonomy: the discipline of naming and categorizing organisms, based on shared traits
- taxonomic factors: morphological traits, developmental features/processes, molecular
- Carolus Linnaeus: who developed a formal hierarchical system of taxonomy?
- binomial scientific naming system: Linnaeus also developed what?
- phylogeny: the evolutionary history of a species or group of related species
- nodes: what depict common ancestors on phylogenetic trees
- systematics: classifies organisism and determines their evolutionary relationships
- systematists mostly use: fossils, morphological data, biochemical data, genetic data
- sister taxa: groups that share an immediate common ancestor
- outgroup: a more distantly related group of organisms that serves as a reference
- polytomy: a branch from which more than two groups emerge
- parts of a phylogenetic tree: sister taxa, branch points, rooted tree, outgroup, polytomy
- homologies: Phenotypic and genetic similarities due to shared ancestry are called __
- homology: a phylogeny must show similarities due to __
- homology: similarity due to shared ancestry
- analogy: similarity due to convergent evolution
- Cladistics: groups organisms by common descent
- clade: a group of species that includes an ancestral species and all its descendants
- monophyletic: a clade is ____ if it consists of the ancestor species and all its descendants
