Teachers and parents! Our Teacher Edition on The Beak of the Finch makes teaching easy.
Peter Boag is a contemporary of Peter and Rosemary Grant’s who conducted research on Darwin’s finches on the island of Daphne Major in 1976 and 1977. During this time, the island was experiencing a major drought, which prevented Boag from conducting the experiments he’d originally planned to. But through the drought—and the selective pressures it placed on the finches—Boag and his team witnessed natural selection in action. Most notably, smaller birds died out while larger ones, who could more easily extract rare seeds from tough pods, survived. By the early 1990s, Boag had pivoted to studying the DNA of Darwin’s finches, becoming one of the first people on Earth to sequence the finches’ DNA.
