PrepTest 73, Passage 1, Setup
Summary
The passage provides a critical examination of the debate between Darwin's theory of evolution and the strict constructionists' perspective, focusing on the role of natural selection and adaptive mutations.
- Darwin's view on evolution emphasizes that it is not solely driven by selection, contrasting with the strict constructionists who argue that evolution equates to selection.
- The author critiques the strict constructionists' stance by highlighting the existence of non-adaptive mutations, which contradicts their theory that all changes must be adaptive for reproductive success.
- Examples of non-adaptive alterations and the Cretaceous extinction are used to further challenge the strict constructionists' views, demonstrating scenarios where their theory does not hold.
- The author employs a disjunctive proof to argue against the strict constructionists, suggesting their assumptions are flawed.
- Ultimately, the passage sides with Darwin's broader view of evolution, critiquing the narrow interpretation of evolution as merely selection by the strict constructionists.
