What is your position on divine intervention, or the lack thereof, in the evolution of life? and specifically in random mutation?
that it's unnecessary, hence random mutation followed by selection, is enough. Accumulation happens of beneficial changes, it's not going straight from no eye to a human eye in one generation, but gradations, from no eye, to light sensitive cells, which increase in complexity over generations, or start working together, then compound eyes, made up of simple eyes, rods, cones. My point is there are many steps in between that we can't see because eyes don't fossilise easily, but there are creatures with simpler eyes today that probably existed before as well.
anyway, my understanding of things is still evolving, so I can't say I have a fixed position on this or anything else.
