Hmm.
I said everyone on earth, and somehow left out myself. I'm getting a 'Twilight Zone' flashback.
See if this helps.
Each of the words "evolution", "fact" and "theory" has several meanings in different contexts. Evolution means change over time, as in stellar evolution. In biology it refers to observed changes in organisms, to their descent from a common ancestor, and at a technical level to a change in gene frequency over time; it can also refer to explanatory theories (such as Charles Darwin's theory of natural selection) which explain the mechanisms of evolution.
It helps if persons would be more specific, because the papers are specific, when it discusses the theory.
