Why Isn't Evolution Considered a Law? From the Web.
This is an issue which often confuses the general public, as the two words, theory and law, have very different common meanings. But in science, their meanings are very similar. A theory is an explanation which is backed by "a considerable body of evidence," while a law is a set of regularities expressed in a "mathematical statement." This is why Newton's Laws of Motion are referred to as laws and not theories. They are expressed with simple equations (like f = ma for his 2nd Law of Motion). Evolution, and most of Biology, cannot be expressed in a concise mathematical equation, so it is referred to as a theory. A scientific law is not "better" or "more accurate" than a scientific theory. A law explains what will happen under certain circumstances, while a theory explains how it happens.
