Darwin: Who wants to live a million years

This not really a Web 2.0 tool but all the same it is an interesting and useful computer based resources. Learn about Darwin's theory of natural selection and see if you can create a species that will survive one million years. "Who wants to live a million years?" is a very engaging interactive. Best played it with senior students it brilliantly shows how genetic variation and selecting pressures result in changes in the gene pool or extinction. Survival is the name of the game.
