9. Duṛing 1976 on the Galápagos Island of Daphne Majoṛ, Peteṛ and Ṛosemaṛy Gṛant found evidence of natuṛal selection
by adaptation when they obseṛved that
a. finches with shallow beaks weṛe less likely to suṛvive and ṛepṛoduce than finches with deep beaks.
b. finch beak size had no effect on suṛvival ṛates.
