The new and amazing findings keep pouring out of the literature. Cyanobacteria are blue-green algae, and so ancient (about 3.5 bya) they appeared about the time life started on Earth. They had to come first or we would not be here. They use photosynthesis for energy (as do all plants generally), burning CO2 and making oxygen as a result. At the time they appeared the atmosphere had very little oxygen, and what became present allowed animal life to appear. - Like many organisms they have a circadian rhythm, which allows adaption to light and dark, day by day. The biochemical mechanism has now apparently been found: http://www.sciencemag.org/cgi/content/abstract/322/5902/697 The article itself describes a complex cascade of biochemical reactions, but note the sentence in the summary about the organism's chromosome changing every day and the changes drive the molecular reactions in one direction only. It looks like Paley's watch mechanism has been found! Unless driven by enzymes many organic chemical reactions can result in back and forth reactions. - The moral: Darwin's mechanisms have only a finite time to create all of this complexity, but the apparent complexity of living matter continues to increase and increase exponentially, continuing to raise the issue: was there enough time for Darwin's theory to create us?
