Web1 de ago. de 2002 · The relationship between brain size and body size is highly ordered. In most vertebrate radiations, brain size varies approximately 10-fold, and brain size increases with body size, although this increase is not proportional. Rather, it is allometric, with slopes ranging from 0.21 (agnathans) to 0.74 (mammals).
