Document Summary
This section will focus mainly at the population level as this is primary unit of evolution. Small questions can help towards solving a big question. Large questions require multiple lines of evidence. Unlikely to be answered by a single experiment. How: proximate involve determining physiological or genetic mechanisms. Why:ultimate determin ecological function and significance of the trait. A variety of approaches are used to address questions; the best studies use more than one source of evidence: Comparative obtain same data from many species. Experimental manipulate a system to address a specific hypothesis; requires an experimental design and statistical analysis. Important assumptions about evolution verified by scientific study (five tenets of natural selection) The variety of life on earth; the number and kinds of living organisms in a given area. Has two meanings; state or process. Any trait(character, feature) that contributes to fitness by making an organism better able to survive or reproduce in a given environment [as a noun]
