No. Time plus primordial soup does not equal macro evolution any more than time plus airplane parts in a blender equals a 747.

Okay, so "old earth" doesn't change your mind about the possibility of micro-evolution gradually resulting in macro-evolution. That still leaves the question of why? Given that micro-evolution happens, what mechanism prevents an enormous sequence of these little changes from accumulating?

I have no idea what mechanism just as scientists have no idea what mechanism limits genetic mutations today. Theologically, God built things so that they would stay confined to a certain amount of change, no more. It's called order, and he really did not appreciate when man would lie with some other species (as in the imaginary part ape-man).
