F.A.Q.: What's Evolution? Is It 'Just a Theory'? - New York Times: "Is evolution 'just a theory'? A 'theory' in science is a structure of related ideas that explains one or more natural phenomena and is supported by observations from the natural world; it is not something less than a 'fact.' Theories actually occupy the highest, not the lowest, rank among scientific ideas. ... Evolution is a 'theory' in the same way that the idea that matter is made of atoms is a theory. Is it true that there is lots of evidence against evolution? No. Essentially all available data and observations from the natural world support the hypothesis of evolution. No serious biologist or geologist today doubts whether evolution occurred."
