dhw: As for guidance, it wouldn't be necessary if they had the intelligence (perhaps God-given) and the tools (like beaks and feet) with which to do their own inventing.-DAVID: Sums up the discussion completely: a giant IF. Your side would have some credence if we could see current modifications or variations of Nature's Wonders.They stay very static as if permanently imprinted within the particular animal.-Once again: if a structure or lifestyle proves successful, there is no need for it to be varied. The question is how it originated. Different organisms may simply have created different structures and lifestyles to suit themselves. Also once again: we do not know of any current innovations - evolution appears to be going through a period of stasis. That is why we can only theorize about origins. All hypotheses would have more credence if we could see God/chance/the IM at work!
