EVOLUTIONARY BIOLOGY EVOLUTIONARY BIOLOGY’S CONTRIBUTIONS TO SOCIETY Human Health and Medicine • Genetic Diseases • Infectious Diseases • Mental Disease • Normal Physiological Functions Agriculture and Natural Resources • Plant and Animal Breeding • Using Biodiversity • Pest Management • Genetic Engineering • Forestry and Fisheries Environment and Conservation • Conservation Biology • Effects on an Ecosystem with the Introduction of New Organisms Understanding Humanity • Human History • Variations with and among Populations • Human Nature • Models of Cultural Change • Comparison to Non-human Primates and other Species Finding Useful Natural Products • Fossil Fuels • Microorganisms GOALS OF EVOLUTIONARY BIOLOGY DISCOVER THE HISTORY OF LIFE ON EARTH • Determine ancestor-descendant relationship among all species that have ever lived (phylogeny) • Determine times of species’ origin and extinction • Determine the rate, course of change, and origin of each lineage’s characteristics • Determine the timing of major genomic rearrangements and the origin of new genetic information UNDERSTAND THE CAUSAL PROCESSES OF EVOLUTION • How hereditary variations originate • How various processes act to affect the fate of hereditary variations • How natural selection, mutation, genetic drift, gene flow, diverse molecular, anatomical, behavioral and other co-acting processes cause evolution • How populations of one species become different species CASE WESTERN RESERVE UNIVERSITY
