Document Summary

Classification (+ systematics): study of diversity of organisms and evolutionary relationships. Binomial nomenclature: genus + specific epithet (ex: homo sapiens) Phylogeny: evolutionary history of species / group ii. Hierarchial - each level more inclusive than the one below. All species at a level share characteristics of that group. Accumulation of genetic changes within a population over time. Changes in allele frequency from generation to generation. Not changes to an individual during their lifetime. Natural selection: one of many mechanisms of evolution -- beneficial traits increase in frequency over generations. Biological diversity is a consequence of evolution c. Phylogeny: evolutionary history of a species or group of species. Phylogenetic tree: representation of evolutionary relationships -- not phenotypic similarity. A: they"re not; usually not considered living a. Subcellular (usually smaller than cells), intracellular (replicate within cells), parasite (use host cell"s resources for own life cycle) Note: there are always exceptions because viruses break all the rules b.
