Brain–body mass relationship for mammals [dubious – discuss]. Brain–body mass ratio, also known as the brain–body weight ratio, is the ratio of brain mass to body mass, which is hypothesized to be a rough estimate of the intelligence of an animal, although fairly inaccurate in many cases.
The central chimpanzee averages 59.7 kilograms (132 lb) in males and 45.8 kilograms (101 lb) in females. [4] Standing they measure on average 96 cm (38 in) for males and 80 cm (31 in) for females.
