Document Summary

Intro to evolutionary biology: chap 1 coyne: intro to evolution. Multiple factors for certain questions in evolutionary biology. Approaches: observational, theoretical(modes, mathematical), comparative(same data from diff species), experimental(manipulative test of a theory). Speciation, common ancestor, gradual evolution, change results from natural selection. Biodiversity: variety of life on earth, number and kinds in a given area. (not just species diversity, also genetic diversity) A) noun- any trait that contributes to fitness by making an organism better able to survive or reproduce in a given environment. B)verb- evolutionary process that leads to the origin and maintenance of such straits. Allows for classification to reflect evolutionary history aka taxonomy& systematics. People here look at genomes, morphology and paleonotology. 2)microeconomics- mechanisms of evolution, natural selection: evidence for evolution, theory for evolution. Keystone of western thought theodosuis dobzhanksy- nothing else makes sense except in the light of evolution. Modern evolutionary synthesis, merging of mendelian and mathematical ideas: biodiversity and adaptation.
