What's with the "E" question?

Now that Scott walker is the front runner for the Republican Presidential nomination the scramble is on to show that he's just another dumb, anti-science, white guy.  During a recent interview on a trip to London, he was asked if he believed in "E-volution."  Walker chose to punt and refused to answer the question.  Here's how I think he should have answered:

"I don't understand the question.''

"Are you referring to Micro or Macro evolution? Microevolution refers to varieties within a given type. Change happens within a group, but the descendant is clearly of the same type as the ancestor. This might better be called variation, or adaptation, but the changes are "horizontal" in effect, not "vertical." The proof of micro evolution is undeniable. For example, humans have evolved into different races and today's humans are larger than their ancestors."

"Macroevolution refers to major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. Macroevolution remains a theory and has yet to be conclusively proven. I'll now be happy to answer any questions directly related to my qualifications for elected office."
