In this biology activity, learners will be investigating evolution by "competing" for food like Darwin's finches might have competed. Each student group is given a different type of "beak" to work with and there are also different kinds of food so that each of the groups is able to compete for the niche that they feel best suits their birds "beak". After allowing time for some birds to become extinct, the environment will change and some of the "beaks" that were not very effective before will enjoy a time of renewed usefulness.
