More about optimal eye design. Is evolution a mathematician?-"Bialek, for instance, discusses compound eyes of insects such as the fly. These compound eyes have a large number of small lenses packed into an array. A large number of small lenses gives high resolution, just as does a digital camera with a large number of pixels.
 
But when the lens becomes too small its optics become distorted due to diffraction. So in determining the best lens size there is a tradeoff between resolution and diffraction. In the optimum solution the lens size is roughly proportional to the square root of the radius of the head. An indeed, Bialek shows an old paper surveying the compound eye designs in more than two dozen different insects. That paper shows that for the different size insects, the lens size is proportional, as predicted, to the square root of the head size."-Or is God the Math professor behind evolution? After all fractals are all over evolution.
