      • Advocates of adaptationism or “adaptationists” view natural selection among individuals within a population as the only important cause of the evolution of a trait; they also typically believe that the construction of explanations based solely on natural selection to be the most fruitful way of making progress in evolutionary biology and that this endeavor addresses the most important goal of evolutionary biology, which is to understand the evolution of adaptations.

  3. Adaptationism is an approach to studying the evolution of form and function. It attempts to frame the existence and persistence of traits, assuming that each of them arose independently and improved the reproductive success of the organism's ancestors. A trait is an adaptation if it fulfils the following criteria:

  5. In its extreme form, adaptationists believe that every anatomic or functional detail observable in an animal should be adaptive; otherwise, they think, it would have never been conserved along the evolution.

  6. A Statement of the Distinctions. Here are the three kinds of adaptationism I recognize: Empirical Adaptationism: Natural selection is a powerful and ubiquitous force, and there are few constraints on the biological variation that fuels it.

  7. Apr 3, 2017 · The adaptationist program offers a framework and approach for testing theories about naturally selected organisms. The Adaptationist Framework. An adaptationist does not assume or purport that all (or even most) features of organisms are adaptations.

  8. Adaptationists regard the consistency of the trait with the hypothesis that it is an adaptation shaped by natural selection as good evidence for the conclusion that it is. Arguments such as Dawkins’, which were meant to demonstrate that the focus of selective forces are individual genes made visible to selection through
