Document Summary
Why questions involve determining the ecological function and adaptive. Comparative - obtain same data from many species. Experimental - manipulate a system to address a specific hypothesis. Small: answering small tractable questions can help solve a big one. Large: unlikely to be answered by one experiment. Type of question - how vs. why how questions involve determining the physiological or genetic mechanisms. Questions in evolutionary biology responsible for aspects of a trait significance of a trait. Approaches used in evolutionary biology (experimental design and statistical analysis) Theodosius dobzhansky - fruit fly geneticist and modern evolutionary synthesis founder. Biodiversity* - the variety of life on earth; the number and kinds of living organisms in a given area. Adaptation* - has two meanings; state or process environment. Most evolutionary change is caused by natural selection. Any trait that contributes to fitness by making an organism better in an. Evolutionary process that leads to the origin and maintenance of such traits.
