Part 3 (Synthesis): Essay Question (1 question, 20 points). Answer ONE of the following questions in the box provided. PLEASE INDICATE WHICH QUESTION YOUR ANSWER ADDRESSES.  Please use full essay format with Introduction, body and conclusion.  Please use detailed examples and answer appropriately for the points allotted.   1.      Does evolutionary theory provide the answer to the origin of new species? Why or why not? Be sure to provide examples of evolutionary studies in your answer (direct and indirect) and discuss the possible routes that have been proposed as mechanisms of speciation. (Be careful, this is not asking about the origins of all life, just one species emerging from another). 2.      “The apparent fixity of species once seemed to be the greatest argument against evolution” (Weiner 1995). How is the fluidity of species we have been discussing an argument in support of evolutionary theory? Be sure to provide examples of evolutionary studies to support your answer. 3.      Irreducible complexity is a primary argument against evolution. In fact, Darwin himself posed the question ‘How do we explain something as complex as an eye or as ornate as the peacocks feather?’ What is meant by the concept of irreducible complexity and how would you with your new found knowledge of evolutionary biology challenge this idea and describe how selection might lead to these complicated structures. Be sure to provide examples of evolutionary studies to support your answer.
