Applied Evolution Why Evolution Matters Simon Howden Belize Evolution Education Workshops, Nov. 2012
Evolution – A Definition (or three) • Variation of inherited traits within a population over time as a consequence of mutation, genetic recombination, or gene flow • Descent with modification • Change over time
Evolution helps explain… • The diversity of life on Earth • How new species are formed • Why organisms look and behave the way they do • How organisms respond to changes in their environment • Why some groups of organisms are more diverse than others
Forces That Drive Evolution • Mutation – Random changes in DNA sequence • Natural selection • Genetic Drift – Change in gene pool due to chance • Gene Flow – Change in allele frequency due to migration
How does all this affect me?Why does evolution matter?How is it relevant to me and my life?
Applied Evolution Using an understanding of the principles of evolution to solve real-life problems and challenges, make improvements to the world around us, or improve our everyday lives.
