Because ideas about evolution by natural selection have never been false what term can be used to describe evolution by natural selection?

Answer 1

We often say the theory of evolution when we refer to the idea that life evolved through natural selection.

Note that the theory of evolution, at least as it is expressed in modern evolutionary synthesis, is far and away the bestexplanation for the countless facts we've discovered about life on earth and its long history here. In that light, modern evolutionary synthesis (MES) is considered fact by almost all of the scientific community.

The fact that the ideas expressed have not been proved false does not keep some from trying. And though the questions raised and the contrary opinions expressed are, in general, healthy for science on the whole, there is an undercurrent of desperate intent on the part of some investigators who attack the theory.
