You still aren't getting it. For a trait to be expressed and a new/different function/organ to exist takes a TON of mutation. How did all the insignificant mutation retain in the code if it didn't yet lead to any improvement??? And if it was maintained, it itself would be mutated away from development of a process. Amino acids don't "help" eyes develop. It's an all or nothing thing. There is no direction Or pathway where when enough building blocks exist suddenly an organ coalesces.
evolution is random. You seem to be forgetting that. It hinders organisms as much as it helps. Natural selection reinforces the mutations that help. BUT, how does that benefit expressed without a new function/adaptation expressed?
It's hard to mutate a species because there is so much dilution of the mutations. It takes a significant advantage to be expressed and increase genetic spread (babies). Humans are too wide spread and not isolated to significantly change now. Imagine that.
Perhaps you would care to explain why you have an appendix, if it hasnt been surgically removed somewhere along the way. Why do you have thick hair in your armpits and in -um, other areas - if, according two two of the worlds major religion, God is offended just by seeing the hair on top of your head. Are these and so many other human features intelligent/inspired design?
