Questions for Discussion: Evolution on Double Time
Discuss the importance of gene duplication as a mechanism for evolution. Why is this phenomenon so important? Explore the literature on molecular evolution to identify and discuss one specific example in which gene duplication and subsequent divergence has been used to explain the evolution of a physical or physiological system in animals. (hint: look for "lysozyme" to get you started) Discuss the phenomenon of gene families. How are they identified? How are their relationships determined?
