The Illustra film, Metamorphosis: The Beauty and Design of Butterflies, does an outstanding job of outlining the enormous problem that metamorphosis poses for a Neo-Darwinian explanation of moth and butterfly evolution.
A spectacular example of a creature that seems to utterly defy naturalistic explanation is the Caribbean reef squid, known by the scientific name, Loliginidae sepioteuthis.
If we are to love God with our minds, as Jesus Christ commanded us, we must commit ourselves to thoughtfully examining the scientific and philosophical arguments (from ALL SIDES) that have bearing on origins issues before adopting any position. Even then, we should hold our view with a good measure of humility and a willingness to continue learning.
