The circadian clock percolates through every aspect of behaviour and physiology, and has wide implications for human and animal health. The molecular basis of the Drosophila circadian clock provides a model system that has remarkable similarities to that of mammals. The various cardinal clock molecules in the fly are outlined, and compared to those of their actual and 'functional' homologues in the mammal. We also focus on the evolutionary tinkering of these clock genes and compare and contrast the neuronal basis for behavioural rhythms between the two phyla.

We thank the BBSRC, NERC and Wellcome Trust for supporting our research, and the Royal Society for a Wolfson Research Merit Award to CPK. We also thank three anonymous referees who put up with, and treated with considerable sympathy, a very rough first draft that was written by one of us (CPK) from memory, during a brief stay in an Italian hospital.
