This game has an interesting premice wherein students make paper airplanes and fly them to touch a box filled with paperclips; each round, surviving students are allowed to modify their airplane. This continues until there is only one or two survivors. The changes that the planes undergo represent evolution. Although the game sounds fun, it sounds as if it would result in a reduction of diversity, which is not an example of evolution at all. It would require some serious modification if it were to be a decent model of evolution.
