Something I learned recently is that evolution is less like a program than I thought; to take an example, if during development you move a proto-eye in a frog to the end of their arm, the eye will still connect to the nervous system, get blood vessels, etc. connected to it. Why in the world does that work? Because morphology is a system that dynamically takes in information and adjusts to it; not a system like "grow a blood vessel exactly here for 2cm". This is why mutations can often not cause immediate "compilation failure" since they just alter a parameter of the environment a specific morphological system is growing in, and the change is usually just noise which the system already has a large buffer of variability it can use to adjust.
