The peppered moth is one of the most famous animals in evolutionary biology. Victorian collections show how a melanic version of this normally speckled species spread through sooty urban areas because its black wings camouflaged resting moths from hungry birds (see picture above). The exact genetic change involved, however, remained elusive. But, in a paper in Nature, Arjen van't Hof of Liverpool University, in England, and his colleagues, say they have nailed it down.
