   An important part of the adaptationism debate concerns the testing of adaptive and non-adaptive hypotheses. The belief that scientific practice in evolutionary biology does not adhere to the proper standards of evidence motivates many of the critiques of adaptationism. This concern has been taken seriously by some evolutionary biologists; for example, Rose and Lauder (1996) claimed that a central task of contemporary evolutionary biology is to articulate a “post-Spandrels adaptationism,” a task that involves improving testing methods by including comparative and molecular data, conducting careful long-term studies in both the laboratory and the wild, and incorporating a more comprehensive understanding of development and constraint.
