The reading for this week includes the following statement: "It is emphasized that scientists, through their investigations, do not prove anything" (GCU, 2014). A similar statement was made in an open letter to the editor of Science: "There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything" (Glieck et al., 2010). While technically true when considering the scientific method, it may be more beneficial to employ a graduated approach by classifying scientific information as "proven, evolving, [or] borderline science" (Moghissi, Amin, & McNulty, 2010).
Read "Does Science Never Absolutely Prove Anything?" by Moghissi, Amin, and McNulty. Then consider the theory of evolution. Do you consider the theory of evolution proven, evolving, or borderline science? Support your answer.
