This program emphasizes the teaching of attitudes, development of process skills, the relationship of social issues to science and technology, the relationship of science with other disciplines, and the organization of the curriculum around unifying themes, rather than topics. Note how the titles of the three grade levels emphasize the key Gestalts needed to thoroughly embrace an evolutionary world view. In this investigation, you will examine evidence for change in horses. The text makes an error in analogy when it compares the intelligent design changes in a bicycle with the assumed chance evolutionary changes in the horse. If we are to teach critical thinking we might ask whether it is logical to cite an intelligent, purposeful process as evidence for a non-intelligent, chance process.
Mutations are mostly harmful, yet beneficial ones are vital to evolutionary theory.
