Bird Beak Variations

Ever wonder why different birds look the way they do? Why are some bird's beaks pointy? curved? long? short? The same questions hold for animals, plants and humans (not beak shapes of course – but other features.) Build an 'arm' with the beak of a bird at the end. Activate it. Discover why it's shaped the way it is. Experiment with picking up different materials with the beaks. Discover anything? Adaptation happens when the need arises for survival.
