Wolves and Rabbits

   In our experiment, a pack of wolves was hunting four types of rabbits in an arctic environment.  The white rabbits had the obvious advantage, since they blended in with the snow, but since what the wolves ate was random (our paper throwing skills were not that great) the fact that they were white was not necessarily advantageous.  However, certain wolves had advantages in this experiment, simply because they were bigger and could cover more rabbits (and thereby eat them).  This size variation was essential to their success or failure, while the differences in rabbits were less important.  Every few generations, a type of rabbit would go extinct, simply by bad luck or the growing number of wolves.  As the number of wolves grew, the number of rabbits fell, until there were not enough to sustain the wolves, which would then go extinct as well, and a new generation of both rabbits and wolves would have to immigrate.  The population of wolves would rise and fall in accordance with the population of the rabbits, and when they both reached their maximum, the wolves would begin to starve and die.  This created a graph of almost sine-like curves, which would intersect every couple generations.
