This work focuses on the intricate structure and function of stomata, microscopic pores on plant leaves regulating gas exchange. Keithley highlights the remarkable complexity of these "tiny servo-mechanisms," emphasizing their precision and efficiency in controlling carbon dioxide and oxygen intake. He then uses this complexity to argue against a gradual evolutionary development of stomata, proposing instead that their design points towards creation. The author presents a classical theory of guard cell action, involving light-stimulated sugar production, pH changes, and osmotic pressure, before ultimately questioning how such a sophisticated system could have evolved through random processes.
