There is an excellent article on this in Scientific American that fully describes the process . Though the caterpillar does break down much of it's unneeded protein building blocks ,it does keep a certain amount of cells that contain DNA that codes for each of an adult butterfly 's organs and body parts. It is important to note that these cells are present way before the butterfly/caterpillar egg hatches. In other words the essential DNA to code a butterfly does not need to change as a caterpillar metamorphosis, it is in fact always present.

Btw Perry no one wants you to be " confrontational " I think that posters are asking you to be responsive, concise, and to address the salient points ,rather than attempt to deflect and obfuscate .
I do thank you however Perry for bringing up the philosophy of naturalism. Truly an interesting philosophy. Where you aware that it was a philosophy that Christians adopted and further developed ?
