Mutation, genetic drift, gene flow, selection. The forces of evolution. Oh and lots of time and a huge amount of luck (not even ants can exist on Venus or Mars), but "luck" is just another word for selection bias, or looking backwards in time. > Where does the leap from nothing to knowledge of that one task come in? There is no sudden leap, only a huuuuuuuge number of tiny steps and lots of complexity of interactions.
