Document Summary
Biol 1202 chapter 26 notes: phylogeny and the tree of life. Phylogeny and the tree of life: systematics: The discipline of systematics classifies organisms based on shared relationships. If organisms (or any items) are to be grouped, then they need a name. All grouping methods are subject to problems. Plants vs. animals was an imperfect system and as a result didn"t last: binomial nomenclature: The foundation for modern classification, binomial nomenclature, was developed by. Linnaeus in the 1700"s: linnaeus came up with names for organisms that were universally accepted, with a first and last name, he also developed a scheme where organisms are classified or grouped into categories. These categories are further divided into smaller and smaller groupings creating an organizational hierarchy: the lowest two categories for the taxonomic hierarchy (genus and species) make up the scientific name for an organism, ex. Homo sapiens: the genus name is capitalized and the species name begins with a lowercase letter.
