Well, you must understand that I don’t think the evidence points toward anything other than unguided evolution, and that there is no evidence against gradualism, if by that you mean the absence of saltation. But if we suppose a guided scenario, there’s no reason for anything sudden or drastic, just tweaking the odd mutation to produce, over millions of years, the few thousand differences between us and the chimp-human ancestor that have any effect on phenotype. Nor do any of these mutations have to happen simultaneously in multiple individuals. They just have to happen and then spread through the population, through drift, selection, or divine nudging.
This scenario has the advantage of being consistent with the data, while separate creation isn’t. All that stuff Joshua showed you: the genetic similarity, the different rates of evolution in X, Y, and autosomal chromosomes, the mutation spectrum of pedigrees matching that of human/chimp differences, is all explained by common descent but is nonsensical given separate creation. He may not have mentioned my favorite evidence: that the genetic and other data fit a tree of descent for all apes, all primates, all mammals, all amniotes, etc., etc. If that’s special creation, the creator is trying to fool you into believing in common descent. Do you think he would do that?
You can’t really spot any of those in the fossil record, though you can find tools. Australopithecines had tools, and they’re intermediate in other ways too. Even chimps make tools. The hominin fossil record is in fact full of intermediate forms.
That’s by no means obvious. Why should God guide evolution similarly in different lineages, if you want to go that way? Why should the same mutations show up by chance in different lineages, if you want to go that way? Chimps and humans have diverged from their common ancestor in different directions, and that’s how evolution generally works.
