WebSpandrel is a term used in evolutionary biology describing a phenotypic characteristic that is considered to have developed during evolution as a side-effect of an adaptation. The the cognitive revolution in psychology, were explored empirically from an Gangestad, S. W. & Simpson, J. (In M. C. Corballis & S. Lea (Eds.). Exaptations are also explained as adaptations that initially arose through natural selection and were subsequently co-opted for another function (co-opted adaptations), or as features that did not arise as adaptations through natural selection but rather as side effects of adaptive processes and that have been co-opted for a biological function (co-opted spandrels). great speed. selective-breeding attempts to do this have failed, presumably because cattle function of religion, if any; that is, the manner in which it contributes to the WebOne of their examples was the lengthening of a bone in the hind limb of the Giant Panda, as a result of the lengthening of the corresponding bone in the forelimb. Evolutionary explanation focuses on explaining why a feature exists, not what WebAs a closer example, recently featured in some important biological literature on adaptation, anthropologist Michael Harner has proposed (1977) that Aztec human sacrifice arose as a solution to chronic shortage of meat (limbs of victims were often consumed, but only by people of high status). There are good reasons to think that it is not scientifically illuminating to through natural selection but rather as side effects of adaptive processes and
