Hey bballad
nihil: sorry should have been more percise. Most main stream christian groups do not take the bible literaly, many includeing the largest christian denomination in the world accept evelution as valid science and feel that thology has no place in science. It is only a small group of radicals that insist on forceign ID on the rest of us.
That is exactly the wavelength I am coming down, evolution happens?
There is also a temporary thing like the moths example, and there are totally transitory effects such as is observed in chameleons?
Thank you for understanding me

For the argument that the eye could never evolve spontaniously:
Nilsson, D.E. and Pelger, S., 1994. A pessimistic estimate of the time required for an eye to evolve. Proc. R. Soc. Lond. B 256:53–58
A computer simulation of gradual eye evolution by Dan Nilsson and Susanne Pelger, which claims, ‘it would take less than 364,000 years for a camera eye to evolve from a light-sensitive patch.’ They start from a light-sensitive layer, with a transparent coating in front and a light-absorbing layer behind.
First, this layer bends gradually into a cup, so it can tell the direction of light rays increasingly well. This continues until it is curved into a hemisphere filled with the transparent substance. Secondly, bringing the ends together, closing the aperture, would gradually increase the sharpness of the image, as a pinhole camera does, because a smaller hole cuts out light, and as there are diffraction effects if the hole is too small, there is a limit to this process. So thirdly, the shape and refractive index gradient of the transparent cover change gradually to a finely focusing lens.
