As Richard Dawkins puts it, “All animals probably have a relatively similar repertoire of proteins that need to be ‘called forth’ at any particular time. . . .” The difference between a more complex organism and a simpler one, “between a human and a nematode worm, is not that humans have more of those fundamental pieces of apparatus, but that they can call them into action in more complicated sequences and in a more complicated range of spaces.” It was not the size of the ship, yet again, but the way the planks were configured. The fly genome was its own Delphic boat.
