Pair bonding is an evolutionary phenomenon in which two individuals form an enduring bond, typically to raise offspring and share resources. The bond can be formed through a monogamous relationship, or a more fluid relational dynamic such as polyamory, depending on the context. It is based in mutual trust and connection, as well as a subconscious drive for the pair to depend physically and emotionally on one another. This can involve forming a family unit, developing emotional and cognitive routines with one another, and in some cases, establishing an interdependent economic relationship. Thus, pair bonding is a symbiosis of emotional and physical connections that gives great benefit to both parties.
