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]
In monogamous species, adult males and females form long-lasting pair bonds. Compared to other systems, there is little competition for mating rights and males and females tend to be similar in size. Polyandry, which involves groups consisting of single females mating with multiple males, may arise as a secondary mating system in monogamous ...
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 ...
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 ...
In both of these species, males and females are monogamous, pair-bonded, and exhibit bi-parental care for their offspring. [25] [42] [24] The social group in both these species consists of female and male parents along with their offspring. [43] [24] Males in these species serve as the primary caregivers and play a major role in infant survival ...
I've learned that both people don't have to be monogamous or nonmonogamous to make a relationship work. I met my partner, Seth, at Burning Man in 2018. We were in the same camp of about 120 people ...
