Detailed explanation-1: -To look different from other species. To be able to eat the food readily available in the environment. To protect itself against predators.
Detailed explanation-2: -Birds that are a part of the same species have different characteristics to help them survive. The different shaped beaks picked up certain types of food better than others. This is the result in physical characteristics in the same species working to give the birds an advantage in their environment.
Detailed explanation-3: -On the Galápagos, finches evolved based on different food sources-long, pointed beaks served well for snatching insects while broad, blunt beaks work best for cracking seeds and nuts.
Detailed explanation-4: -On the Galapagos Islands, Darwin also saw several different types of finch, a different species on each island. He noticed that each finch species had a different type of beak, depending on the food available on its island. The finches that ate large nuts had strong beaks for breaking the nuts open.
Detailed explanation-5: -Which of the following best explains the beak variation among these four species of finch? Competition for food resulted in selection for different beak types.
