Peter and Rosemary Grant began studying the Galapagos finches in 1973. For about 40 year's, they studied the finches on Daphne Major. Why was this an ideal place to study the evolution of the finches?

This was an ideal place to study the evolution of the finches because basically due to Daphne's climatic conditions, they found a natural environment with an extreme climate, oscillating between periods of severe drought and abundant rainfall, as well as an uncontaminated environment that had never been visited by humans, which provided a wide natural selection for research on finches.
