The Beak Of The Finch by Jonathan Weiner

This is one of the easiest-to-read, most exciting books on evolution of the past twenty years. It describes evolution happening before our eyes among the isolated bird populations of the Galapagos - the very finches observed by Darwin on his Beagle voyage - and its heroes are an unsung British couple. It is uncannily fascinating to imagine the beak of the finch changing in our lifetime in response to evolutionary pressure. . . .
