One of the central tenets of evolutionary biology is the conservation of morphological and behavioural characteristics in response to environmental demands. When challenged by the demands of a changing ecosystem, organisms typically adapt by successive modifications of existing biological machinery rather than the development of entirely new systems. A case in point involves the use of metabolic machinery which is responsible for the gradient maintained between a cell’s internal and external environment. All differentiated cells actively maintain a selective ionic gradient across the cell membrane. When these cells are aggregated at the tissue level, a combination of epithelial cell-to- cell cohesion and polarity in the distribution of ionic pumps create and maintain appropriate internal salt and fluid levels within the tissue with respect to the external environment.
