II-1. Describe the Miller-Urey experiment. Is it one of the “genes first” or “metabolism first” models. Explain why. II-2. From an evolutionary standpoint, why is the small genome of the virus a fitness advantage? II-3. Why is it important to use homologous traits in phylogenetic analyses? How would you determine that the traits you are examining are homologs? Give examples. II-4. How does the Stepping Stone model of migration differ from the Isolation by Distance model of migration? Define migration. How would you test the basic assumptions of these models?
