The concepts of microevolution and macroevolution are examined, focusing both on their similarities and differences. It is concluded that at least 17 criteria exist that demonstrate macroevolution is not merely an extension of microevolution as is often claimed by Darwinists. But, instead, they are two different processes that involve distinctively different mechanisms. A major difference is that microevolution has been demonstrated empirically, whereas macroevolution is largely the product of speculation. Another key difference is that microevolution involves loss of information, and macroevolution involves a gain of new information. A common approach to proving macroevolution is to demonstrate microevolution, and then infer by extension that macroevolution also has been proven. While this "bait and switch" tactic may be useful to win arguments, it does not justify the conclusion.
