A STANDARD TACTIC USED by creationists to attack evolution is to contrast microevolution (i.e., within species evolution, which they accept) with macroevolution (i.e., between species evolution, which they adamantly reject). Microevolution, they grant, may or does occur. But they assert that macroevolution either has never been observed or is theoretically impossible. They argue that while microevolution may be true, it is trivial, and the major claim of evolution — the evolution and emergence of species — is either unsubstantiated or false.
I argue in this article that creationism faces its own micro/macro distinction and challenge, and that ID has so far only focused on and made claims about microprocesses. Finally, I posit that whatever achievements microcreation may have made or may have imagined it made, these achievements neither strengthen the case for macrocreation nor weaken the case for macroevolution.
