DAVID: In fruit flies glial cells guide connecting neural connections to the brain:

DAVID’S comment: Embryology must follow a plan. How did evolution develop those plans for reproduction? This is a major question current theory does not answer, because there is so much biochemical signaling that is used to guide the production and migration of newly minted cells. Embryology requires design, and is the best argument for God I can find.

dhw: Thank you for yet another eye-opening article. I agree that such complexities are the best arguments for your God. If he does exist, the question whether he preprogrammed them all 3.8 billion years ago, personally dabbled them, or created a mechanism enabling organisms to work out their own developments remains wide open.

'Wide open" only for you. Giving organisms mechanisms for their own development present the same problems of complexity that have you recognize the 'best arguments' for God. Why have Him give a 'mechanism' which is second-hand design? If He could do that why not directly do it firsthand? Makes a lot more sense.

But besides God's abilities, there is no other obvious way to explain embryologic development. Chance? Never. Your suggestion?
