3 Chаrles Dаrwin оbserved finches (birds) in the Gаlapagоs, a grоup of islands off the coast of South America. Darwin’s observations helped develop his theory of evolution by means of natural selection. The diagram shows the common ancestor and some of the finch species now living in the Galapagos. See Addendum for Figure 3 The large ground finch has a large beak and feeds on big seeds with hard seed coats. The cactus finch feeds on nectar from cactus flowers. 3.1 Explain how the beak of the cactus finch could have evolved by natural selection. (4) 3.2 One of the Galapagos islands is called Fernandina. Suggest why the large ground finch is found on Fernandina but the cactus finch is not. (2) 3.3 A student uses 400 clay models of mice to investigate natural selection. He paints 200 of the clay models white and 200 brown. He places the model mice in woodland in the morning. He checks the models in the evening for damage by predators. The graph shows his results. See Addendum for Graph 3 3.4 Calculate the difference between the number of damaged white model mice and the number of damaged brown model mice. (1) 3.5 Suggest why the results would differ if the student used live white mice and live brown mice rather than clay models. (2)
