Totally off topic...
I was moderately disturbed when my opthamologist's assistant told me she'd been "created", and didn't come from slime.
I silently hoped her beliefs didn't interfere too much with her medical expertise, but I bet it does.
As soft tissues fossilize poorly if at all, relying on the lack of exactly what a soft tissue was as an indicator there was no soft tissue at all, ignoring the other features that supported the soft tissues, such as bone structures, which do fossilize and are comparable to extant specimens is naive and superficial.
"The eye" exists in many forms, all of which suit the animal possessing them, and some animals have lost the eye itself, while retaining the structures that supported it when it was useful to the ancestor of the current animal. Other needs for survival negated the expenditure of the energy to generate and support a useless organ.
It's Darwinian.
