A walking stick is an insect, not a plant/animal hybrid.
Despite the insult to all walking sticks who go by that name and are generally honored as such by the common man (you know, the hybrid name) I don't suppose design has anything to do with it. Is there something about the walking stick that says to you it cannot be a product of intelligent design? If so, what is it? If not, then why is it inherently unscientific to suggest it might be?
