“No transitional schemes can be constructed to explain the emergence of the more complex systems from the simpler ones found in bacteria on account of lack of homologous features conserved across the kingdoms. In laboratory experiments, considerable design input is needed to construct the simplest artificial biological clock; these do not run on a 24-hour cycle. The existence of circadian clocks, with fundamental common design elements, specified complexity, and functional coherence, argues for the existence of a designer.”
