Document Summary

Populations: this section will focus mainly at the population level as this is primary unit of evolution. Small; answering small tractable questions can help contribute towards solving a big questions. 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 signi cance of a trait. A variety of approaches are used to address questions; the best studies use more than one source of evidence: Experimental manipulate a system to address a speci c hypothesis; requires an experimental design and statistical analysis. Important assumptions about evolution veri ed by scienti c study. Lineages split or branch by speciation resulting in the generation of biodiversity. Most evolutionary change results from natural selection the only process responsible for the evolution of biodiversity and adaptation. Biodiversity the variety of life on earth; the number and kinds of living organisms in a given area.
