A high-ranking male mandrill advertises his status with bright facial coloration. [1]In the zoological field of ethology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system.
The results indicated that alpha male Capuchin are the preferred mate for adult females. However, only the alpha females had strong interactions with the alpha males by virtue of a dominance hierarchy among the females in which only the most dominant and strong females were able to interact with the alpha male.

Dominance signals are typically associated with ethology. However, humans display such signals as it is an innate characteristic. Fundamentally, all social species must have expressions of dominance and engage in hierarchy systems to function. [19] Men exhibiting greater dominance signals often have higher success mating with women.
In many Polistes wasps, monogamy is established soon after colony formation by physical dominance interactions among foundresses of the colony including biting, chasing, and food soliciting. Such interactions create a dominance hierarchy headed by larger, older individuals with the greatest ovarian development.
Elephants can use their ears as threat displays in male-to-male competition. Sexual selection in mammals is a process the study of which started with Charles Darwin's observations concerning sexual selection, including sexual selection in humans, and in other mammals, [1] consisting of male–male competition and mate choice that mold the development of future phenotypes in a population for a ...
Taxonomic rank is a classification level in biological taxonomy, such as species, genus, family, order, class, phylum, and kingdom.
