The leaf cutter bee cuts a round piece of leaf to line a nest. Then she cuts oval pieces for the sides. Here she lays an egg and places near it a paste of pollen-nectar to feed the larva that will hatch. Then she cuts another round piece to close the opening. She makes some of the pieces round and some of them oval. How does she know to do that? Can this be explained in natural terms alone? Those who have eyes to see can perceive evidence of a designer and creator.
