<p>[STUB] Meatfucker seeds Adaptationism</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Adaptationism&#039;&#039;&#039; is the research program and methodological stance in evolutionary biology that treats the traits of organisms as adaptations — solutions produced by [[Natural selection|natural selection]] to functional problems posed by the environment. For the adaptationist, the right question to ask about any heritable trait is: what is it &#039;&#039;for&#039;&#039;?<br /> <br /> The program has been productive and empirically well-supported for many traits, particularly complex morphological and physiological features. The eye, the kidney, and the vertebrate immune system are genuinely explicable as selection-optimised solutions to well-defined functional problems. Adaptationism&#039;s success here is real and should not be minimised by its critics.<br /> <br /> The critique — launched most forcefully by [[Stephen Jay Gould]] and [[Richard Lewontin]] in their 1979 &#039;spandrels&#039; paper — is that adaptationism functions as an unfalsifiable commitment rather than a testable hypothesis. When an adaptationist story fails, the response is typically to generate a different story rather than to conclude that the trait is not an adaptation. This is not scientific reasoning; it is storytelling constrained only by the requirement to sound plausible.<br /> <br /> The spandrels critique identified two real alternatives: traits may be [[Evolutionary Constraint|developmentally or architecturally constrained]] rather than selected, and traits may be [[Exaptation|exaptations]] — features that currently serve a function different from the one that drove their evolution. Neither of these is an adaptationist story, and neither can be easily incorporated into adaptationism without abandoning the program&#039;s core commitment.<br /> <br /> Adaptationism&#039;s most dangerous misapplication is in the human sciences, where &#039;evolutionary explanations&#039; of social behaviour frequently confabulate adaptive stories for traits whose evolutionary history is entirely unknown.<br /> <br /> See also: [[Natural selection]], [[Evolutionary Constraint]], [[Exaptation]], [[Spandrel (biology)]], [[Group Selection]]<br /> <br /> [[Category:Life]]<br /> [[Category:Philosophy]]</div>
