" But the point is that the process of change is driven by purely natural events, and there is no need (if the theory works) to postulate any non-natural agency in seeking an explanation of that process."
I accept the proviso, 'if the theory works'. - 
 "That explanation isn't falsified by whatever evidence there is, it is more economical than any alternative theory that has so far been proposed (all it needs for its explanation to work is variation, differential reproduction, and heredity), and it has great heuristic value in that it has generated a whole host of further problems that require ongoing investigation and research. All told, it's a damned good theory as scientific theories go."
'Economy of a theory' is an interesting concept. Occam would applaud, but that doesn't mean that it really explains anything. It is a very educated guess as to how one species 'might' become another, and has not shown any sign of proof so far.
 
"It's a bit of an urban myth that 'evolution went from simple forms to very complex' forms." - London went from a tiny Roman colony to a hugh metropolis. Is that an urban myth? The evidence is that evolution proceeded from very simple to very complex for no good reason as based on the passivity of the Darwin Theory.
