Before we actually delve into Darwin's dangerous idea, let's take a look at some common assumptions about evolution. Many people have misconceptions about the theory, and this page is designed to put several of them to rest.
People seem to have the strange idea that "evolution" is a theory that starts by predicting the big bang thirteen billion years ago and continues on through the formation of more complex elements from simple hydrogen, followed by the genesis of the solar system, and finally life arising from nonliving matter. Not only is this a ridiculously inflated and false version of actual evolution, it is often oversimplified and caricatured, so that in addition to assaults on biology, attacks on "evolution" subsume objections to physics, cosmology, chemistry, geology, and thermodynamics. Some creationist organizations have created not just an alternate form of biology ("creation biology"), but also a "flood geology". Every field of science that seems to contradict the literal interpretation of Genesis is assumed false and lumped under the general label of "evolution", although many precede Darwin's theory by decades (scientists had inferred the Earth was hundreds of millions of years old by the 1830s, for example).
Neither is evolution an all-encompassing bias that starts with the assumption that the Earth is billions of years old instead of hundreds. "Answers in Genesis", in particular, has attacked an "evolutionary worldview": one where scientists start interpreting the data with evolution in mind in order to cast evolution in a favorable light. Look back at the page on the scientific method, and you'll see that it does not invoke evolution at all.
Evolution is also neither random change nor instantaneous change. While I played Pokemon years ago (and enjoyed it, I might add), the "evolution" pokemon go through is not real evolution, but is rather metamorphic. Charmander does not actually evolve into Charmeleon, it transforms; evolution is not an individual phenomenon, but rather a population-wide one. And evolution is not a random change; it is not chance and only chance, although chance plays an important role. Fred Hoyle's famous "tornado in a junkyard" analogy has nothing to do with evolution because it assumes evolution is only chance change.
Finally, evolution is not micro- and macroevolution. Often, a line is drawn between microevolution and macroevolution. In the past, it was drawn at speciation; now, it's often drawn at the "addition of information to the genome". The only distinction between micro- and macroevolution is the length of time over which you survey the effects of natural selection. The amount of information the genome encodes is irrelevant to evolution; all that is relevant is survival.
