I will ignore you penchance for quote mining and refer you to the following.....
Modern researchers have been putting forth work on the topic. D.E. Nilsson has independently put forth four
theorized general stages in the evolution of a vertebrate eye from a patch of photoreceptors.
[5] Nilsson and S. Pelger published a classical paper
theorizing how many generations are needed to evolve a complex eye in vertebrates.
[6] Another researcher, G.C. Young, has used fossil evidence to
infer evolutionary conclusions, based on the structure of eye orbits and openings in fossilized skulls for blood vessels and nerves to go through.
[7] All this evidence adds to the growing amount of evidence that supports Darwin's
theory.
I have highlighted the keys words which are theorized, theorising, infer and theory. Notice, no facts only supposition. Please forgive me but I don't base anything on supposition or theory.
