Explaining natural wonders (Animals)

dhw: Thank you for confirming the process I keep trying to describe. Shapiro tells us that bacteria are sentient, cognitive, intelligent beings. That means they deliberately rewrite their DNA to develop new ways of reaction.

I am with Shapiro until he introduces the word 'cognitive' which implies thought. 'Sentient' is correct. Bacteria receive stimuli and recognize them and respond.

dhw: It is the ability to rewrite DNA to develop new ways of reaction/new organs that constitutes the inventive mechanism, and according to Shapiro that ability is conscious.

Understood, not accepted as conscious.

DAVID's comment on the parasitical fly: I judge God's help in these situations by looking at the complexity involved. By that standard I think God may have helped the flies learn how to parasitize ants, but the beetles eating behaviour may well be a learned epigenetic instinct.

dhw: I can't help wondering why God felt he had to help the fly to parasitize the ant in order to balance nature in order to supply food in order to keep life going in order for humans to appear. Is it not possible that the fly and the beetle both found out what to do all by themselves? I find it hard to believe that your background in physiology traps you into rejecting the latter explanation.

I don't use physiology in my decisions of this sort.
