Document Summary
Scientific discipline focused on classifying organisms and determining their evolutionary relationships. Scientific discipline concerned with naming and classifying the diverse forms of life. A named taxonomic unit at any given level of classification. Evolutionary history of a species or group of related species. Types of characters (features of organisms) used to reconstruct phylogeny. Protein sequences, gene sequences, position of genes on chromosomes. Similarity in characteristics resulting from a shared ancestry. Similarity between two species that is due to convergent evolution rather than to descent from a common ancestor with the same trait. A similar (analogous) structure or molecular sequence that has evolved independently in two species. Pertaining to a group of taxa that consists of a common ancestor and all of its descendants. A monophyletic taxon is equivalent to a clade. Pertaining to a group of taxa that consists of a common ancestor and some, but not all, of its descendants.
