Espès yo te evolye divès konpòtman sosyal ak estrateji kwazman an repons a fòs selektif nan anviwonman yo. Pandan ke promiscuity se estrateji nan matant dominant atravè toupatou ki pi vertebrate, evolisyon konverjan nan sistèm monogamus yo te rive plizyè fwa atravè liyaj byen lwen. Monogamous konpòtman yo panse yo dwe fasilite pa yon kapasite nerobyolojik yo fòme epi kenbe selektif atachman sosyal, oswa lyezon pè, ak yon patnè mating. Mekanism yo neral nan pè konpòtman lyezon yo te envestige pi rigorously nan mikrotin rat, ki montre divès òganizasyon sosyal. Syans sa yo make mezolimbic dopamine, neuropeptides sosyal (oxytocin ak vasopressin), ak lòt sistèm neral yo kòm faktè entegral nan fòmasyon, antretyen, ak ekspresyon de obligasyon pè.

Species have evolved diverse social behavior and mating strategies in response to selective forces in their environments. While promiscuity is the predominant mating strategy across most vertebrate taxa, convergent evolution of monogamous mating systems has occurred multiple times across distant lineages. Monogamous behavior is thought to be facilitated by a neurobiological capacity to form and maintain selective social attachments, or pair bonds, with a mating partner. The neural mechanisms of pair bonding behavior have been investigated most rigorously in Microtine rodents, which exhibit diverse social organizations. These studies have highlighted mesolimbic dopamine pathways, social neuropeptides (oxytocin and vasopressin), and other neural systems as integral factors in the formation, maintenance, and expression of pair bonds.
