Most scientists originally reject the theory of continental drift since it did clearly explain continents would move. This is a theory that has been established by Wegener and did not get good support initially.
Alfred Wegener
Wegener's theory of continental drift is supported by a vast quantity of evidence, which is why scientists have accepted it.
The continental drift theory is the theory that once all of the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations.
Alfred Wegener started the search which then caused scientists to start the search. They eventually proved his theory.
This is the elaboration of a theory.

If new observations do not fit exactly with the current theory.
Most scientists originally reject the theory of continental drift since it did clearly explain continents would move. This is a theory that has been established by Wegener and did not get good support initially.
Alfred Wegener's continental drift theory has subsequently been honed by scientific discoveries to the more all-inclusive plate tectonic theory which is generally accepted by earth scientists.
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.
