Explain Why is it important to use homologous traits in phylogenetic analyses? How would you determine that the traits you are examining are homologs?

Part II, Hypothesis testing EACH ANSWER SHOULD BE ONE OR MORE PARAGRAPHSII-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?
