Encephalisation.

Abstract

Encephalization is a measure of brain size relative to body size that has been proposed to reflect a species' cognitive ability. The use of encephalization as a proxy for cognitive ability is based on an interpretation of brain–body scaling as a causal relationship; that is, a given gram of body tissue requires a given mass of brain tissue to coordinate its function. Deviation from brain–body scaling would therefore reflect selection for brain expansion associated with enhanced behavioral, or cognitive, traits. Although some support for this hypothesis is provided by covariation between measures of encephalization and ecological traits, such as dietary behavior and seasonal variability, recent data on brain composition, evolution, and genetics suggest a more complex relationship between brain size and cognition.
