The cell theory states:
At the time when this theory was a-brewing, it was difficult to provide conclusive data and evidence.
Instead of just stating his own personal opinions John Dalton cited evidence to support his atomic theory. The giving of evidence - which could be proved or disproved by others - was what soon resulted in his theory being accepted by scientists.
Wegener's theory of continental drift is supported by a vast quantity of evidence, which is why scientists have accepted it.

Real scientists do not "gather evidence in support of" any theory. The technical term for that kind of thing is "cherry-picking". Real scientists build a theory to explain the evidence that they have already gathered, and then test the theory to see whether it holds water. The easiest, fastest way to make sure that you are regarded as a wingnut by real scientists is to adopt or invent a theory, and then spend your time trying to prove it.

The Aryan race was something made up by German scientists, which they based off of Darwins theory of Evolution. Therefore it cannot have a timeline.
modify the theory or discard it altogether.

Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
In the 1960's scientists uncovered new evidence that seemed to support Wegener's theory.
There was no evidence to prove it
Fossils.
Wegner's theory was not accept because he didn't have much evidence to support his theory with and scientists thought that there might have been a land bridge between the continents. Another reason to why his theory was rejected was that he was a foreigner, by that; the scientists didn't really take him seriously.
