The field developed from comparative psychology, including the study of animal conditioning and learning. Brain-to-body mass ratio, also known as the brain-to-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. Several species have female-biased sexual dimorphism, with the females being larger than the males.

On April 2, 2013, the White House proposed a major national project to unlock the mysteries of the brain—the Brain Research through Advancing Innovative Neurotechnologies (Brain) Initiative.

The case lasted 10 years, involved the only police raid on an animal laboratory in the United States, triggered an amendment in 1985 to that country's Animal Welfare Act, and established PETA as an internationally known organization.

The largest animals on the planet are not the only ones to have large body parts, with some smaller animals actually having one particularly enlarged area of the body.

The male that wins a fight may also have the chance to mate with a larger number of females and will therefore pass on his genes to their offspring.
