Spandrel Biology

Spandrel biology

That is, it is a trait that is not particularly advantageous to have, though it is retained because it is not particularly harmful to have.

The term "spandrel" originated as an architectural word for the roughly triangular space between the tops of two adjacent arches and the ceiling. These spaces were not actually utilized until later on, when artists realized they source make designs and paint in these small spandrel biology, enhancing the overall design of the building.

This defined the biological concept and argued the case for a structuralist view of evolution. Adaptationism is a point of view that sees most organismal traits as adaptive products of natural selection.

Spandrel biology - think, that

Architectural spandrel in the Basilica di San Marco , Venice In evolutionary biology , a spandrel is a phenotypic characteristic that is a byproduct of the evolution of some other characteristic, rather than a direct product of adaptive selection. The term originated during the Roman era as an architectural word for the roughly triangular space between the tops of two adjacent arches and the ceiling. These spaces were not actually utilized until later on, when artists realized they could make designs and paint in these small areas, enhancing the overall design of the building. Stephen Jay Gould , a paleontologist at Harvard , and Richard Lewontin , a population geneticist , borrowed the word to apply to secondary byproducts of adaptations that were not necessarily adaptive in themselves. In their paper, Gould and Lewontin employed the analogy of spandrels in Renaissance architecture : curved areas of masonry between arches supporting a dome that arise as a consequence of decisions about the shape of the arches and the base of the dome, rather than being designed for the artistic purposes for which they were often employed. The authors singled out properties like the necessary number of four and their specific three-dimensional shape. At the time, it was thought in the scientific community that everything an animal has developed that has a positive effect on that animal's fitness was due to natural selection or some adaptation.
