One of the attacks against Darwin’s evolution, is that it is “just a theory”. Religious groups use the term regularly to down play its importance, and create doubt that it has not been tested. Theories have been repeatedly tested… For most that have taken science classes in the past, you would say when an idea is put forth without being able to be retested just yet, that is a hypothesis. Here is an article on the differences between Hypothesis, Theory, and Law. It turns out that the term law has been replaced with the term theory. Well now computers can drive the evolution of biological enzymes without human imput. Known as the “evolution-machine” or the “Darwin chip”, it may just be the future in the classroom.
