Slusher believes the earth is 7000 to 10,000 years old.[6] He is an opponent of Albert Einstein's theory of relativity.[7]
Biology: A Search for Order in Complexity
In 1974, Slusher co-edited the revised edition of the creationist textbook for students, Biology: A Search for Order in Complexity.[8] The textbook was developed by the Creation Research Society and published by Zondervan. It was negatively reviewed as a pseudoscientific textbook that misrepresents biological evolution.[8][9][10] A negative review in The Science Teacher noted that the "text grossly distorts the biological theory of evolution, so much that it is barely recognizable".[8] The textbook does not define natural selection and falsely leads its readers to "believe that evolution is the result of chance mutation, when in fact it is the result of selection acting on genetic variability which arises ultimately by mutation. The picture of evolution presented in this book is wrong and flagrantly so".[8] The review also noted that the textbook falsely defines evolution as the "ameba to man" theory where organisms of one "kind" change into another "kind".[8] In 1977, an Indiana state superior court determined that the use of the textbook is unconstitutional (see Hendren v. Campbell).[11][12]
