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.
