from my understanding of evolutionary theory, the belief is that random mutations and natural selection operate together in producing new species. (so both processes need to be focused on; not one or the other.)
however, the fact that these mutations are random in a naturalistic sense does not say anything about whether or not God planned them.
it seems to me that God, being all powerful, could plan out random mutations.
I would consider it entertaining to create a universe of foward moving rules and see where it lead to.
Just look how popular SimCity and other such games are.
