The Beak of the Finch: A Story of Evolution in Our Time

It is a very good account of the incredibly important work on evolution done by the Peter and Rosemary Grant on Daphne Major island in the Galapagos.

Those observations by Darwin helped shape is conception of natural selection, and the more recent work by the Grants is a modern day demonstration that Darwin was right.
