After Darwin proposed his ideas about natural selection as a mechanism for evolution, it took time before evolution was generally considered a theory. Why do we now refer to it as a theory?

Question

anonymous · Answer

we predicted stuff with the theory of evolution, and these predictions were found to be real by experiments.

a theory is a thought-of mechanism to explain things we see. it is considered right until someone disproves it scientifically. and since no one has disproved the idea of evolution yet, we now call it a theory. =)
