Among Darwin’s inches, natural selection has been responsible for changes in the shape of the beak corresponding to characteristics of the available food supply. Because beak morphology is a transmissible trait, a beak better suited to the distribution of available seed types would become more common in subsequent generations. Suppose that the act of eating hard seeds caused individual birds to develop bigger beaks. Would this lead to an evolutionary increase in beak size after a drought? (Use Lamarck’s theory of evolution in your answer.)
