The theories contributing to Modern biology: The Cell Theory, Gene Theory, Homeostasis, and the Theory of Evolution by Natural Selection.

I have read my text and I still do not totally understand the four theories that contribute to Modern Biology. I would appreciate if you could give me a brief outline of the theories, including the theorists, the dates, and the basic concepts of the theories.
