The Harvard-trained palaeontologist Kurt Wise who studied under Gould interestingly makes the following claim that the schizochroal eye is good evidence for design because it exceeds the needs of the trilobite.
Since when is it good design to have a needs exceeded rather than simply met? That an eye has a greater than necessary requirement speaks volumes to the contrary. An evolving eye would likely be arrived at with whatever materials are at hand capable of performing the necessary function regardless of whether they were suboptimal or of capacity exceeding the needs of the creature.
If we follow this logic then what are we to logically conclude about eyes that are not great in regards of the creature they belong to?

But I realize now that these people were not in science; they didn’t understand it. They didn’t understand technology; they didn’t understand their time. R.P. Feynman

Re: good evidence not "good" design
randman
To think in terms of good design posits one knows the intent of the Designer
Then how should an eye that exceeds its needs {what are the needs of a trilobite?} be evidence of design?.Why are there then animals whose eyes are less than that necessary for their enviroment? Rhinos for instance? Or blind cave fish who possess eyes?

First you said.

Now you say
randman writes:
"good" refers to the design hypothesis being the best and only explanation.
Substituting the latter definition into the former statement makes no sense. Perhaps you can clarify?
Regardless, we are discussing this statement are we not?
The design of the schizochroal eye makes it unique among eyes; perhaps even to the point of being the best optical system known in the biological world. This design, in fact, seems to far exceed the needs of the trilobite. The origin of the design of the schizochroal eye is not understood by means of any known natural cause. Rather, it is best understood as being due to an intelligent (design-creating) cause, through a process involving remarkably high manipulative ability.
The word "good" is not present here. My question remains pertainent to this quote. Despite the fact that there are expalnations that involve natural causes the difficulty remains. When we purport the existence of a designer, whose existence is questionable and who's intent is murky beyond this, can the statement that it is the result of an intelligent design be considered "understood"?
