BIOL 204 – Principles of Organismal Biology Lecture Outline 7 – Evolution III: Species & Taxonomy Learning Objectives: Differentiate among different mechanisms of evolution ( mutation , migration , genetic drift , and natural selection ) – which is most common? What is a species (according to Biological Species Concept )? What is speciation ? Distinguish between allopatric and sympatric speciation Distinguish between vicariance and dispersal What is taxonomy and why is it important? Recognize and employ binomial nomenclature I. Mechanisms of Evolution a. If evolution is a change in gene frequency within a population from one generation to the next, what are the mechanisms for change in gene frequency? i. Mutation – random change to a gene ii. Migration – genes move from one population to another iii. Genetic Drift – random sampling error over generations (pretty common mechanism) 1. Founder Effect – small population breaks off from another
