The Beak of the Finch

Summary

An accessible account of Peter and Rosemary Grant's decades-long study of Darwin's finches on the Galápagos island of Daphne Major. Weiner explains how the Grants measured beak size and survival across generations to document natural selection unfolding within human lifetimes, year by year. The book reframed evolution for general readers as an observable, measurable process rather than a slow abstraction confined to the fossil record.
