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]
Range and density of non-human primates. Primates is a diverse order of placental mammals which includes monkeys, lemurs, galagos, lorisids, tarsiers, and apes (including humans). Members of this order are called primates. The order currently comprises 505 extant species, which are grouped into 81 genera. The majority of primates live in South ...
Ambiguity tolerance–intolerance was formally introduced in 1949 through an article published by Else Frenkel-Brunswik, who developed the concept in earlier work on ethnocentrism in children [3] In the article which defines the term, she considers, among other evidence, a study of schoolchildren who exhibit prejudice as the basis for the existence of intolerance of ambiguity.
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 ...
For example, ape has been used either as an alternative for monkey or for any tailless, relatively human-like primate. [ 5 ] [ 6 ] Sir Wilfrid Le Gros Clark was one of the primatologists who developed the idea of trends in primate evolution and the methodology of arranging the living members of an order into an "ascending series" leading to ...
For example, several studies have shown that performance is better on, for example, a color discrimination (e.g. blue vs green) after the animal has learned another color discrimination (e.g. red vs orange) than it is after training on a different dimension such as an X shape versus an O shape. The reverse effect happens after training on forms.
Examples include many moth, butterfly, and fish species that have "eye-spots". These are large dark markings that help prey escape by causing predators to attack a false target. For example, the gray hairstreak (Strymon melinus) shows the false head at its rear; it has a better chance of surviving an attack to that part than an attack to the head.
