Shelford's law of tolerance is a principle developed by American zoologist Victor Ernest Shelford in 1911. It states that an organism 's success is based on a complex set of conditions and that each organism has a certain minimum, maximum, and optimum environmental factor or combination of factors that determine success.

In apes, including humans, heritability estimates of personality dimensions range from 0.07 to 0.63. [24] In horses, heritability estimates range mostly between h 2 =0.15 and h 2 =0.40 for traits assessed in personality tests. Values at this level are considered as "promising" for artificial selection. [25]
Over the course of the 20th century, it became a seminal text in the field of comparative psychology, significantly influencing the study of apes. [ 3 ] [ 4 ] [ 5 ] The increased interest was "followed by nearly a century of German primate research, observations of gorillas in Germany’s sophisticated zoos, and public funding for the study of ...
A tolerance interval (TI) is a statistical interval within which, with some confidence level, a specified sampled proportion of a population falls. "More specifically, a 100×p%/100×(1−α) tolerance interval provides limits within which at least a certain proportion (p) of the population falls with a given level of confidence (1−α)."
Recently, most non-human theory of mind research has focused on monkeys and great apes, who are of most interest in the study of the evolution of human social cognition. Research can be categorized in to three subsections of theory of mind: attribution of intentions, attribution of knowledge (and perception), and attribution of belief.
There are a variety of proposed mechanisms by which social grooming behavior has been hypothesized to increase fitness.These evolutionary advantages may come in the form of health benefits including reduction in disease transmission and stress levels, maintenance of social structures, and direct improvement of fitness as a measure of survival.
The killer ape theory or killer ape hypothesis is the theory that war and interpersonal aggression was the driving force behind human evolution.It was originated by Raymond Dart in his 1953 article "The predatory transition from ape to man"; it was developed further in African Genesis by Robert Ardrey in 1961.

Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
