Caterpillars and Butterflies

The transformation of a caterpillar into a butterfly is marvelous. A new theory on how evolution created such wonder speculates that it arose when an insect met a worm and aspects of both designs were retained in the resulting organism. It's like saying a seaplane arose when an airplane met a boat. But is this any worse than the conventional "explanation" which tells us nothing?

Most biologists believe these [larval stages that look nothing like the adults] evolved gradually, perhaps because natural selection favored juvenile stages that differed from the adults and thus would compete less with them.

Such silliness is what happens when science is driven by religion.
