As far as i understand it, the theory of evolution still states that there are random mutations. And through natural selection and survival of the fittest, useful mutations proliferate.

But when I look at nature... I just don't see that many random mutations. Organisms and species seem to be set up to RESIST mutation through things like spontaneous abortion and DNA repair mechanisms and social and sexual aversion to mutations, etc.

And random mutations seem to almost always seem to be bad. To me, it seems that for evolution to have worked through random mutation, there would constantly be tons of horrible mutations in the present and in the fossil record.

It seems to me there must be some kind of biochemical system in organisms and perhaps even in ecosystems that guides mutations.

Kind of like how if the numbers of males and females in a frog population gets wonky, suddenly some of the frogs will start changing sexes. This shows the on some level, their bodies are interacting with the environment with a certain level of cellular intelligence.

I believe this would explain the 'leaps' in evolution we see. And also explain all of the phenomena that religious people chalk up to the invisible man in the sky.
