Seeing Evidence Of Inept Design

Our first post is a response to "Rosa's" article entitled:
"Seeing Evidence of Inept Design"

Well, it seems as if "Rosa" is the only human being on the planet who missed the entire point that the human eye is not "Ineptly designed" after all, but is rather SPECIALIZED in regard to it's functionality.

However, as noted by EVONEWS:


"The implications of these findings have not been lost on expert optics commentators. A striking article at Phys.org about this new paper, "Fiber optic light pipes in the retina do much more than simple image transfer," reflects a keen awareness of the debate over whether the vertebrate eye is suboptimally designed. It concludes that the retinal architecture, as it now stands revealed, settles the debate. In the words of Phys.org, the notion that the vertebrate eye is suboptimally wired "is folly." Why? Because "Having the photoreceptors at the back of the retina is not a design constraint, it is a design feature." Here's the full passage from the article:
Having the photoreceptors at the back of the retina is not a design constraint, it is a design feature. The idea that the vertebrate eye, like a traditional front-illuminated camera, might have been improved somehow if it had only been able to orient its wiring behind the photoreceptor layer, like a cephalopod, is folly. Indeed in simply engineered systems, like CMOS or CCD image sensors, a back-illuminated design manufactured by flipping the silicon wafer and thinning it so that light hits the photocathode without having to navigate the wiring layer can improve photon capture across a wide wavelength band. But real eyes are much more crafty than that. A case in point are the Müller glia cells that span the thickness of the retina. These high refractive index cells spread an absorptive canopy across the retinal surface and then shepherd photons through a low-scattering cytoplasm to separate receivers, much like coins through a change sorting machine. A new paper in Nature Communications describes how these wavelength-dependent wave-guides can shuttle green-red light to cones while passing the blue-purples to adjacent rods. The idea that these Müller cells act as living fiber optic cables has been floated previously. It has even been convincingly demonstrated using a dual beam laser trap. In THIS case (THIS, like in Java programming meaning the paper just brought up) the authors couched this feat as mere image transfer, with the goal just being to bring light in with minimal distortion. (Emphasis added.)"

Welcome to the first day of the rest of your life, Rosa Rube.
