By analysing genomic sequences in echolocating mammals it is shown that convergence is not a rare process restricted to a handful of loci but is instead widespread, continuously distributed and commonly driven by natural selection acting on a small number of sites per locus; analyses involved sequence comparisons across 22 mammals, including 4 new bat genomes, and found signatures consistent with convergence in genes linked to hearing or deafness, but surprisingly also to vision.
