This concept is fundamental to all of biological and medical science today, as well as many other scientific disciplines. Evolutionary theory, as it is understood and used in science today, is also widely misinterpreted, misapplied and misunderstood by most people. Clearly, any biology course today which does not fully and accurately present and use the theory of evolution is a woefully incomplete biology course. Just as importantly, because a clear and accurate understanding of evolutionary thinking rests on a clear and accurate understanding of science, learning about the nature of modern science should precede learning about evolution . Both of these topics are probably most effective and useful when presented very early in the biology course.
Science deals only with natural patterns and mechanisms.
Understanding science enables one to differentiate it from pseudoscience and non- science. Scientific knowledge is uncertain, tentative and subject to revision. Scientific explanations and interpretations can neither be proven nor disproven with certainty. Scientists use a variety of criteria to compare explanations and select the better ones. Several independent lines of evidence confirm that the earth is billions of years old.
