These keywords were added by machine and not by the authors. Thus, a large brain would primarily reduce. The mechanisms by which enlarged brains are supposed to enhance survival are cognitive, and include inventing new behaviors and adjusting old behaviors to new situations (Fig. Assuming that this buffering capacity increases with the size of the brain, the hypothesis suggests that brain expansions might have been an adaptive solution to environmental changes. 1993 Allman 2000), posits that the essential role of the brain is to buffer animals against environmental variation. The hypothesis, first formulated by Allman and colleagues (Allman et al. ![]() The cognitive-buffer hypothesis (CBH) is an attempt to explain why some animals have evolved large brains despite substantial energetic and developmental costs. ![]()
