Jonathan Weiner's most famous book was published in 1994 and entitled The Beak of the Finch: A Story of Evolution in Our Time. The book is about two scientists' account of 21 years in the Galapagos Islands, where they were able to define evolution as an on-going process that alters wild populations by natural selection. This book received the 1995 Pulitzer Prize for General Non-Fiction and the Los Angeles Times Book Prize for Science. Many critics view it as "the perfect sequel to Origin of Species."
On a desert island in the heart of the Galapagos 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.
In this dramatic story of groundbreaking scientific research, Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself. The Beak of the Finch is an elegantly written and compelling masterpiece of theory and explication in the tradition of Stephen Jay Gould.
