My only concern with this is that if God actually was directly involved in the speciation of life on earth in a physical and tangible way, a reliance on solely materialistic causalities would tend to miss whatever evidence might actually be left behind to indicate this (if any).
And what exactly would we expect to see if a god has been involved speciation? However you then give youself the out that the supernatural entity may act but conceal her actions! Aren't there qualified biologists in the ID movement who would have discovered have uncovered and supposed evidence? I can only conclude that ID is pseudoscience.
Let's use Occam's Razor and exclude a hint-hiding deity from the explanation from speciation.
