The Beak of the Finch

by Jonathan Weiner
New York: Vintage Books, 1994. 352 pages.

From the publisher: "On a desert island in the heart of the Galápagos archipelago, where Darwin received his first inklings of the theory of evolution, two scientists, Peter and Rosemary Grant, have spent twenty years proving that Darwin did not know the strength of his own theory. For among the finches of Daphne Major, natural selection is neither rare nor slow; it is taking place by the hour, and we can watch." Praised by the Washington Post Book World for its "[e]vocative writing, exhaustive research, and Weiner's memorable portrait of the engaging Grants," The Beak of the Finch won the Pulitzer Prize for General Non-Fiction in 1995.
