The evos look at fossils and attempt to extrapolate plausible history. By “evos” I mean those who adhere to macroevolution. I think its safe to say that we have reached a consensus on both sides to accept microevolution (fka adaptation.) The ID people look at mathematical probabilities of designs of similar complexity arriving by chance.
If it was just a matter of a disagreement over whether it was verifiably random or possibly directed, it might be easier. A quick read of the threads should tell you that's not nearly all there is to it.
