Progress in science occurs in fits and starts, and paradigm shifts occur when evidence can be marshaled to support a new point of view.

Evidence-based reasoning underpins all scientific thinking, and it involves testing hypotheses or theories against data. Validating a theory requires replicable measurements from independent groups with different equipment and methods of analysis. Convergence of evidence is critical to the acceptance of a scientific idea.

Science is evidence-based and provides a continuing understanding of complex natural phenomena. Our understanding is constantly evolving and continually improving.
