Document Summary
Phylogeny: the evolutionary history, systematics concerned with classifying organisms and determining these organisms" relationships. Invented by carolus linnaeus: 2 part name, genus + specific epithet. Homo sapiens = humans: rules, always in latin, genus capitalized but species isn"t, always in italics or underlined, genus name can be abbreviated, genus unique, specific epithet not unique. Taxa grouping of organisms at any one of the levels: each level is more inclusive than the one below it. 26. 4: fig 26. 5, homology shared ancestry, derived from common ancestor. Evolution: accumulation of genetic changes within a population over time. Changes within allele frequencies: natural selection mechanism by which evolution occurs, mechanism of evolution, acts on variation of phenotype, acts on the individual. General characteristics: nonliving particles, not cells, cannot carry out metabolic activities on own, cannot reproduce on their own, contain genetic material, genetic material. Have either dna or rna: very small. Discovery of viruses: tobacco mosaic virus (tmv, adolf mayer 1883.
