Examples

    Designs, Intelligent and Stupid

  • This is an example of a byproduct or what Stephen Jay Gould famously called a spandrel -- a trait that has no benefit and can be very costly, but remains in the population by being connected to other traits that do have a benefit.

  • "The 'Stephen Jay Gould line' was that scientists were too quick to apply evolutionary explanations to everything. Some features of our lives did not result from adaptation, he argued, but are just accidental by-products of other evolutionary changes. Gould called these biological artifacts 'spandrels.'"
    -- Christine Kenneally, The First Word, p54

  • In Stephen Jay Gould's "pluralistic evolution" schema, he used spandrel as a metaphor to indicate an exaptationary structure. A spandrel is a byproduct of an otherwise purposeful construction, which, then, in a biological rather than architectural process of natural selection is used as 'fresh meat' for further adaption. In architecture, a spandrel, being a serendipitous space, is frequently the site of decoration.

  • 1. In architecture, the roughly triangular space between the left or right exterior curve of an arch and the rectangular framework surrounding it.
