Molecules-to-man evolution requires new information to arise where there was none before. So-called microevolution, on the other hand, simply turns pre-existing genetic options “on” or “off.” Because of this, the terms microevolution and macroevolution are very misleading since they imply that microevolution is “baby steps” toward molecules-to-man evolution, which is false.
For instance, finches develop different beak sizes and shapes by modifying the amount and timing of something called BMP4 (a bone morphogenetic protein). Tinkering pre-existing knobs and switches is certainly not an example of molecules-to-man evolution. For that, we would need completely new knobs and switches altogether in order to create completely new types of animals.

- Coyne, 2009, p. 32: “Even some creationists will admit that minor changes in size and shape might occur over time–a process called microevolution–but they reject the idea that one very different kind of animal or plant can come from another (macroevolution).” ↩
