| before anyone brings up the "irreducable complexity" of the eye as a proof of intention in creation, and a falacy of evolution, let me refute that. the human eye has optic nerves that go over the rods and cones in the back of our eyeballs. if god had created us in his image, as the bible explains, why did he give us eyes with these things that obscure our vision, while giving a squid an eye with optic nerves that don't get in the way of rods and cones?
Furthermore, the eye isn't irreducibly complex. By plugging in physical equations for optics, and developing an algorithm (a program/model that searches for the best possible solution, i.e. best focus and definition being output), starting with a simple sheet of light-sensitive material, the computer turns out a spherical shape, with a lens in front to focus light just right. A computer can do it with math in a relatively short time. Why couldn't nature (which selects for the best eyes, plus or minus some physical constraints) do the same over millions of years?
There are no irreducibly complex organs, its just that the scope of evolution is misunderstood. billions of years is far beyond what we can imagine, and in that time, using the simple laws of nature and selecting for the best possible, we get what we have right now. megadiversity. every animal has some shortcomings that are just a product of some tendon getting stuck in the way or whatever, and through this byproducts of evolution, you can even track the course of evolution. Nothings perfect. We have big brains and abstract thought (therefore, science, technology, society, language) because it affected mate choice. Squids have better vision than us because they didn't have the same physical constraints worked into the evolution of their eye.
Any questions?
