An example of simile in science journalism:
"Tumour cells are often fundamentally unstable, barely staying ahead of their own chromosomal aberrations, but many bacteria have a sort of gearing system. Under stress, they will switch to more error-prone replication modes. This emergency system is a survival advantage (which is why it's persisted): with a greater number of mutations, the chances of producing new variant cells that can survive is increased. It's true that many of these mutations will be of little help, or might even cause the cells carrying them to die more quickly, but this mechanism only gets activated when the bacteria are in danger of dying off anyway if nothing is done."
