In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of young and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s [ 1 ] that is frequently used in sociobiology and evolutionary biology circles.
Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases ...
Vasopressin is a hormone that induces a male Prairie vole to mate with one female, form a pair bond, and exhibit mate-guarding behavior (i.e. increase the degree of monogamous behavior). [4] The presence of vasopressin receptor 1A (V1aR) in the ventral forebrain is associated with pair bonding, which is necessary for monogamy. [15]
Though strict monogamy is rare in nature, some primate bonded pairs demonstrate monogamous (or partially monogamous) mating systems. [8] In some monogamous pair-bonded species there have been observations of extra-pair copulations, wherein a male or female member and a partner of the opposite sex, other than the so-called mate, have been ...
Gibbons, on the other hand, are an example of monogamous primates that can be described as “monomorphic,” meaning males and females appear the same with little to no sexual dimorphism. [2] The correlation between mating system and dimorphism in haplorhines likely indicates sexual selection is the driving force behind dimorphism in species ...
For anyone with even a glimmer of interest in non-monogamy, Giles says that just identifying that compulsive mononormativity exists can be the first step in exploring non-monogamous identities ...
