The physicist and philosopher of science Thomas Khun would call this a paradigm shift, if the theory is wide-ranging enough. The shift to Darwinian theory, or any future shift away from it in the future would be considered paradigm shifts. This idea comes from Khun's controversial 1962 book "The Structure of Scientific Revolutions". The book continues to be influencial in the study of the philosophy of science. Relativity was a paradigm shift, as was Quantum Theory.
That's true. A theory es exactly that - theory... Results from experimentation can prove or disprove a theory.
Actually never, a theory is always in danger of being replaced by a better explanation. This does not invalidate the theory, it just means it was not as comprehensive and explanation of observations as was thought. An example of this is Newtons laws of gravity, they are still usable but we now know that Einstein's space/time bending by the mass of an object is a more comprehensive explanation.
A theory is an idea system with a lot of evidence to support it--for example, the theory of evolution. A law (in science) is an idea system with proof attached to it--no contradictions--example, the law of gravitation.
A theory, when proven over time, can become a law. Example: Law of Gravity and Theory of Evolution
A hypothesis is a statement made for the sake of argument. It becomes a theory when it has been independantly verified. It is not a fact or truth. A theory only has to have one contradictory example to lose its status as a theory.
