Document Summary
Prof: spencer barrett: introduction to evolution section, how evolution is studied, biodiversity and adaptation, projects in the barrett lab. Readings and background: chapters in coyne why evolution is true , background knowledge in high school; mendelian genetics, inheritance, structure of. Small; answering small tractable questions can help contribute towards solving a big question. How questions; (=proximate questions) involve determining the physiological or genetic mechanisms responsible for aspects of a trait. Why questions (=ultimate questions) involve determining the ecological function and adaptive significance of a trait. A variety of approaches are used to address questions; the best studies used more than one source of evidence. Comparative; obtain some data from many species. Experimental; manipulate a system to address a specific hypothesis, requires an experimental design and statistical analysis. Important assumptions (verified) about evolution verified by scientific study: Organisms on earth have changed through time. Lineages split or branch by speciation resulting in the generation of biodiversity.
