David: Your only escape from this problem is if you recognize that an inventive mechanism in cells comes with full-blown plans.

Another example is the issue of sea to land transition of animals. We do have walking fish, and we have amphibians, but there is a huge fossil gap that does not explain the jump from sea to land:

"About 400 million years ago a group of fish began exploring land and evolved into tetrapods -- today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries"

The jump happened, but is as much a problem as the dragonfly and the Cambrian.
