DAVID’s comment: Darwin rejected saltation, and saltation requires design. The Cambrian is an enormous saltation and offers the strongest evidence against the gradualism the Darwin theory requires.

dhw: You and I and many other believers in the theory of common descent – including some of Darwin’s own contemporaries – have long, long, long since rejected Darwin’s rigid adherence to gradualism. You and I and many others have also rejected his reliance on random mutations. Time to move on?

Even Darwin could not explain the Cambrian. Accepting God does.
