And any argument trying to say "our evolution is being subtly directed and manipulated by a supreme being" is self-defeating. On both sides of the argument.
Because if an omnipotent being can do something as huge as alter the course of evolution through his will, then there's no point in either (a) trying to find proof of God because he could insert or hide any proof or disproof he wanted, or (b) trying to view any natural processes from a scientific viewpoint because anything we discover could be changed by God.
This treads dangerously close to the idea of "oh, God created the earth 6,000 years ago with all those fossils already in the ground just to fool us"...
