N2 - This article evaluates a thesis containing three interconnected propositions. In a biological sense there are two main types of pair bonds exhibited in humans: social pair bonding and sexual pair bonding. Second, pair-bonding facilitated the idiosyncratic life history of hominins, helping to provide the massive investment required to rear children. Brief relationships are usually, but not always, associated with rather simple courtship activity. [11] More recently the Australian Murray cod has been seen maintaining pair bonds over 3 years. It most commonly takes place between family members or friends, but can also develop among groups, such as sporting teams and whenever people spend time together. For about four days immediately prior to egg-laying, when copulations lead to fertilization, the male bank swallow is very busy, attentively guarding his female. Most people in the USA identify marriage as a natural goal for humans, with love as a necessary component. Pair bonds (social and/or sexual) are a biological phenomenon and are not equivalent to the human social institution of marriage. Some cultures allow the dissolution of marriage through divorce or annulment. On the one hand, sex differences in reproductive investment, and resultant differing potential reproductive rates, are argued to favor elevated mating effort behavior in males (i.e., a short-term, multiple mate seeking orientation; Symons, 1979) and polygyny. However, when most people think about marriage, they think about “love” being at its base, and are really asking about the “the romantic pair.”  To figure out a basis for romantic love we need to explain the particular strong relationship between two people we call the pair bond. No, not opposed at all, rather two types that can occur together or separately. Becoming Human: Evolution of pair-bonding. But are all married couples sexually pair bonded and/or socially pair-bonded? “We don’t fully understand the evolution of human pair-bonding so I welcome this effort,” says Hrdy. The term often implies either a lifelong socially monogamous relationship or a stage of mating interaction in socially monogamous species. Humans are a species that forms long-term pair bonds, but it’s certainly not a monogamous species. Before this time, as well as after—that is, when her eggs are not ripe, and again after his genes are safely tucked away inside the shells—he goes seeking extra-pair copulations with the mates of other males…who, of course, are busy with defensive mate-guarding of their own. Marriage is also an important way in which cultures officially recognize and sanction the sexual pair bonds that characterize human beings. The study dug into the personalities of both the humans and cats and found that the bond between them was complex, much like the bonds between pairs of humans. But, unfortunately, in some cases this is a scenario where science and cultural perceptions do not agree. In humans and other mammals, these pair bonds are created by a combination of social interaction and biological factors including neurotransmitters like oxytocin, vasopressin, and dopamine. Timing The point in time associated with lineage separation events may change in the future as the scientific community agrees upon better time estimates. At this juncture, it’s critical to mention that the current view of marriage that dominates the Judeo-Christian religions and the cultures that are intertwined with them (like ours), is a fairly recent occurrence in human history. [10] Another mouth brooding cichlid – the Lake Tanganyika cichlid (Xenotilapia rotundiventralis) has been shown that mating pairs maintain pair bonds at least until the shift of young from female to male. These bonds can be temporary or last a lifetime, same age or with different age groups, opposite or same sex. It is sometimes used in reference to human relationships. Monogamy is NOT natural. Basically, social scientists and historians agree that marriage (in both secular and religious systems) is best viewed as a social system for legitimizing reproduction and inheritance of property, control of and regulation of sexual activity, and, recently, the culturally sanctioned outcome of romantic “love.”. … In a biological sense there are two types of pair bonds: the social pair bond and the sexual pair bond. These species-specific differences have shown to correlate with social behaviors, and in monogamous prairie voles are important for facilitation of pair bonding. In fact, pair bonding is one of the hallmarks of the human species (Tsapelas, Fisher, & Aron, 2010). The humans then left for two minutes, before returning for a two-minute reunion. The social pair bond is a strong behavioral and psychological relationship between two individuals that is measurably different in physiological and emotional terms from general friendships or other acquaintance relationships. Maybe this shift indicates that our cultural perceptions are finally beginning to catch up with what we know, biologically, about human pair bonding and sexual behavior. Humans can experience some or all of the above-mentioned varieties of pair bonds in their lifetime. For example, recent studies show that extra-pair copulation frequently occurs in monogamous birds in which a "social" father provides intensive care for its "social" offspring. Each step is progressively different and important. How best to characterize the human mating system is a subject of intense and polarized debate. it's just that ALWAYS when people read of two types suggested,no matter what those types are, they are phylogenetically programmed to read them as dichotomies ... and I felt that point needed making. T. moorii broods exhibit genetic monogamy (all eggs in a brood are fertilized by a single male). Orangutans: exploded harems.

A crucial step in recent theories of human origins is the emergence of strong pair-bonding between males and females accompanied by a dramatic reduction in the male-to-male conflict over mating and an increased investment in offspring. First, romantic love is a "commitment device" for motivating pair-bonding in humans. Scientists were able to change adult male montane voles' behavior to resemble that of monogamous prairie voles in experiments in which vasopressin receptors were introduced into the brain of male montane voles. (2012) Race, monogamy and other lies they told you: busting myths about human nature. It took 120 hours of observing 40 cat-human pairs for scientists to conclude that the bond between the two can be similar to other human relationships. and Gray, P.B. We can have social pair bonds with our relatives and our closest friends. Pair bonding in humans helps explain extreme "bonds" that we may share with others but are unable to articulate in terms of contemporary "love".

In contrast, serial monogamy involves partners forming a series of shorter term pair bonds lasting long enough to raise the resulting offspring. Second, pair-bonding facilitated the idiosyncratic life history of hominins, helping to provide the massive investment required to rear children. First, romantic love is a "commitment device" for motivating pair-bonding in humans. Pair-bonding is a term coined in the 1940s[1] that is frequently used in sociobiology and evolutionary biology circles. Humans also have sexual pair bonds both heterosexually and homosexually. 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 offspring and potentially a lifelong bond. In life-long monogamy, two partners form a pair bond that continues throughout their lifespan. Attempting to summarize the evolution of romantic love and pair-bonding in humans is an enormous task. In a number of insects, birds, and mammals, the males display on a common courtship ground called a lek or an arena. How such a transition from promiscuity to pair-bonding could be achieved is puzzling. [9], In the cichlid species Tropheus moorii, a male and female will form a temporary monogamous pair bond and spawn; after which, the female leaves to mouthbrood the eggs on her own. The attachments we form to our romantic partners are designed to keep people together. [7], When discussing the social life of the bank swallow, Lipton and Barash state:[4].
