Peter and Rosemary Grant have worked side by side for 35 years in the Galapagos Islands, the famed Pacific archipelago that inspired Charles Darwin to formulate his theory of evolution. The Grants have followed in Darwin’s footsteps, conducting the most significant evolutionary field study of all time. Their work on Darwin’s finches demonstrates how natural selection produces species that exquisitely match their environments. The Grants and their adventures in the Galapagos are the subject of the Pulitzer Prize winning book Beak of the Finch by Jonathan Weiner. As a couple who have spent much of their career living isolated on tiny islands in the Pacific Ocean, the Grants have many captivating tales to tell.
