  1. THE IMPORTANCE OF EXPERIMENTAL STUDIES IN EVOLUTIONARY BIOLOGYDouglas J. Futuyma and Albert F. Bennett

  2. The major approaches to analyzing evolutionary processes: • Experimental Evolution • Studies of Natural Populations • Comparative methods

  3. Advantages- Replication and control. Disadvantages –suited to laboratory rather than to natural situations. Experimental Evolution

  4. Natural Populations • Advantage- offer ecological realism • Disadvantage - lack of ability to replicate results and control variables.

  5. Advantage- widely used method to understand evolution of characters in the natural world. Disadvantage- Correlational Assumption of parsimony Comparative Methods

  6. Trade-offs- adaptive gain and correlated loss. Escherichia Coli Genetic Drift – a founder event (or bottleneck in population size) may initiate new paths of adaptive evolution. Drosophila pseudoobscura 2 Examples of the Contribution of Experimental Studies to understand Evolution
