. ''Aquilegia'' petals show an enormous range of petal spur length diversity ranging from a centimeter to the 15 cm spurs of ''Aquilegia longissima''. Selection from pollinator shifts is suggested to have driven these changes in nectar spur length. It was shown that this spur length diversity is achieved solely through changing cell shape, not cell number or cell size. This suggests that a simple microscopic change can result in a dramatic evolutionarily relevant morphological change.
