From what I understand:
Darwin's theory of evolution (by natural selection) is called a theory because it's a possible model (maybe / maybe not directly observable), but that life forms "evolve" (undergo change) is an observable fact.
- tomp 12y agoNo, the "theory" means "explanation", nothing more, nothing less. Just like "the theory of gravity". Or tide - we all know what tide is and how it happens, and if you explain how it happens (physically), you might call the explanation "the theory of tides" [1].
