Probably one of the main reasons is that, as our knowledge expands, we realize that the early versions of the theories were just special cases of more general theories.\n\nThe best example of this is Newtonian physics versus Einstein's Relativistic Physics.  Newtonian physics was all well and good when all we could measure were speeds that we could achieve under muscle power on earth, but once we began to be able to measure things like the speed of light, Newtonian physics was no longer able to adequately explain some features.  Along came other scientists who further modified and expanded on Newtonian physics to incorporate the new knowledge.  Einstein derived the best set of equations to explain what we knew -- his equations could both explain and predict Newtonian physics AND the relativistic physics that was being revealed.\n\nAs time passes, we will eventually find that Einstein's Relativity Theories are special cases of some even grander description of the universe.
