Given this is true: Mutations slightly alter an organism’s genetic material which later generations inherit. On rare occasions the alterations are beneficial, enabling those offspring to reproduce more of themselves and the improved genetic material. After many generations, dramatic changes, even new organs, accumulate.
How then: What mutations could improve a larva? Certainly none that destroyed its nerves, muscles, eyes, brain, and most other organs, as occurs within a cocoon. So even if a larva improved, it later ends up as “mush.” From an evolutionary standpoint, liquefying complex organs is a giant step backwards.
Darwin: "If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous successive, slight modifications, my theory would absolutely break down."
