Document Summary
The evolutionary history of a species or group of species. Systematics are used to reconstruct and interpret phylogenies. A discipline focused on classifying organisms and determining their evolutionary relationships. A potential source of confusion in constructing a phylogeny is similarity due to convergent evolution rather than to shared ancestry. Distinguishing between homology and analogy is critical in reconstructing phylogenies. Corroborative similarities and fossil evidence can help distinguish between homology and analogy. Another clue to distinguishing between homology and analogy is the complexity of the characters being compared. Analogous structures that arose independently are also called homoplasy. Binomial is a two-part format of the scientific name. First part of a binomial is the name of the genus to which the species belongs. The second part, called the specific epithet, is unique for each species within the genus. The taxonomic system is named after linnaeus, the linnaean system.
