MACROEVOLUTION ESSAY: (i) Discuss the rоle оf hоmeotic genes in controlling аnimаl development. Your discussion should mаke clear the specific aspect of development that is determined by homeotic genes, and include example(s) to illustrate your explanation.  Also, at a molecular level, explain how homeotic genes regulate other cells to achieve this developmental outcome.  (ii) Discuss why a mutation to a homeotic gene can be an important macroevolutionary event. Your response should include a clear discussion of the characteristics of macroevolution (hint: what characteristics distinguish macroevolution from microevolution) and the type of evolutionary change associated with macroevolution (as opposed to microevolution), and why a mutation to a homeotic gene can be an important event that results in macroevolution.
