He didn't do the study of the Galapagos Finches. The people who studied these birds were biologist Peter Grant and Rosemary Grant. They looked at beak size and shape. The finches are commonly called Darwin's finches, however, they really were not studied by him. They used to finches to study Darwin's Theory of Evolution by Natural Selection. In order for NS to occur there must be variation in a population, variations must be heritable, the species must be reproductively successful, and the survival and reproduction of an individual must be nonrandom. The Grants came up with 4 postulates based on the NS model. 1. Is the finch population variable? 2. Is some off the variation among individuals heritable? 3.Do individuals vary in their reproductive success? 4. Are survival and reproduction nonrandom? The overall conclusion that they made was that: when all four of Darwin's postulates are true in a population, the population will evolve; and that evolution an occur over a short period of time.
