Article Some Problems for Theistic Evolution Some Problems for Theistic Evolution Robert C. Newman Most readers of Perspectives on Science and Christian Faith are acquainted with the terms “young-earth creation,” “old-earth creation,” and “theistic evolution.”1 These reflect the fact that, among Christians in general and within the American Scientific Affiliation in particular, there is considerable disagreement on how to relate the biblical and scientific data on origins. Some feel that theistic evolution is not the best solution. Here I wish to suggest why, by examining some problems for theistic evolution, both scientific and theological. Before looking at these problems, we will need to consider what theistic evolution is, and try to sort it into its various versions. After all, different forms of theistic evolution may face different problems.
