The theory of evolution‚ formalized by Charles Darwin‚ is as much theory as is the theory of gravity‚ or the theory of relativity. Unlike theories of physics‚ biological theories‚ and especially evolution‚ have been argued long and hard in socio-political arenas. Even today‚ evolution is not often taught in primary schools. However‚ evolution is the binding force of all biological research. It is the unifying theme. In paleontology‚ evolution gives workers a powerful way to organize the remains of
