A '''tautology''' is a statement that is already true by definition, not because of any logical deduction<ref>http://www.apologetics.org/glossary.html</ref>. For instance, "All triangles have three sides" is an inherently true proposition, but it doesn't tell us anything new.
The concept of the [[Survival of the fittest]] is a tautology if fitness is defined as the ability to survive.
