title: Evolution: setting the mutation rate.
abstract: A recent study of X-chromosome and autosome genes in mammals suggests that selective trade-offs are important in the long-term evolution of mutation rates; but recent studies with bacteria show that high mutation rates can nonetheless evolve in the short term in clonal populations.
