Evolutionary science, like all natural sciences, is vulnerable to over-enthusiasm, fraud, and mistakes. That does not somehow render it not a science.

I didn't say it wasn't. I was saying abiogenesis was kaput, remember?

Nobody faked the Grand Canyon. Nobody faked the painfully obvious fact that successive geological layers yield successive biological features which have an obvious morphological serial flow to them.

Nobody faked the Cambrian explosion either.

Nobody faked the extra-ordinary correlation between the morphological fossil flow and the tree of relationships established by DNA mutational distance mapping.

I'm reserving judgement on this one. I think there is some dispute on the molecular clock.

Remember, the biggest challenge evolutionists face now is irreducible complexity. If this challenge prevails other explanations must be found for the things you mentioned such as mutational distance mapping and the fossil record.

There is "some dispute" in every nook and corner of the science game. The cavils about the molecular clock are silly distractions. The fact is that ever since Fitch and Margoliash started doing it back in the 70s, we haven't had a single clock tell us that, say, chimps preceeded blackbirds in the human family tree. The quibbling is about the clock discrepencies, which are not surprising, and in the details of relatively new and minor genes over very short mutational distances, about whose history we are quite uncertain, just as one might expect. For the genes whose changes charactarize big branches in the tree of life established by the fossil record, the DNA clock has been astonishingly high-fidelity with respect to the fossil record's tree connectivity graph.

Remember, the biggest challenge evolutionists face now is irreducible complexity.

Only in the minds of creationists. To real scientists, its the same kind of yawner that fossil gaps are: a willful denial of what science, and its limits are.

If this challenge prevails other explanations must be found for the things you mentioned such as mutational distance mapping and the fossil record.

Uh huh. And how, exactly, will we explain the Grand Canyon's layering of fossils, or the astonishing correlation between the fossil family tree graph and the DNA family tree graph? God laid an incredibly expensive trap for unbelievers? That's one messed up God, if you ask me.

I've always been curious why anyone thinks the Cambrian explosion was anything special.

The Cambrian explosion occured shortly after mountains heaved up above sea level, and started leaching tons of calcium into the ocean every year. Without calcium there can't be much by way of fossils. Naturally, you are going to suddenly see a lot more fossils turn up at this point in the record.
