Actually JCL i disagree with you here: the mechanism of natural selection precludes any kind of guiding by a conscious force.

The essence of natural selection as proposed by Darwin is necessarily guided only by fitness to survive. The process by which selectable changes occur is genetic mutation. Genetic mutation is understood as innacurate DNA replication.

The only possible area for the "hand of God" would be in the DNA errors, and this is akin to saying anything random on the chaos level is God. Perhaps unfalsifiable, but explanitorily impotent. And it may even be falsifiable: I'm not a molecular biologist, but i suppose there are theories for how DNA errors occur in replication.
