Understanding natural variations, within and across species, provides knowledge that has energized multidisciplinary sciences ranging from ethology and evolution (Ophir et al., 2008, 2012) to molecular biology (Bendesky et al., 2017), to psychology (Feldman, 2017) and emerging fields such as “precision” medicine. This page was last edited on 22 May 2020, at 10:44. Oxytocin also has a central role in the formation of selective social bonds between mothers and offspring (Keverne and Kendrick, 1992), between adults (Carter, 1998) and also in paternal behavior (Kenkel et al., 2012; Rilling, 2013). The finding led the team to the chemicals that fit with those receptors -- namely, vasopressin and the reproductive hormone … 31, 332–341. doi: 10.1016/0003-3472(77)90066-5, Emlen, S. T., and Oring, L. W. (1977). doi: 10.1002/ab.2480150406, Reburn, C. J., and Wynne-Edwards, K. E. (1999). Animals that experienced higher levels of parental care in early life exhibited higher levels of alloparenting and a facilitation of pair bonding later in life (Bales et al., 2007a; Perkeybile et al., 2013; Del Razo and Bales, 2016).

These animals may be driven by hormones and impulses much like our own, Carter explains. For these reasons, explanations for species and individual variations in social behavior were initially discussed in terms of evolution, fitness, and reproduction (Kleiman, 1977; Dewsbury, 1987; Komers and Brotherton, 1997; Lukas and Clutton-Brock, 2013; Klug, 2018). doi: 10.1111/j.1601-183X.2004.00036.x, Shapiro, L. E., and Dewsbury, D. A. Endocrinol. Manipulations of vasopressin alter aggression differently across testing conditions in monogamous and nonmonogamous Peromyscus mice. Klopfer, P. H. (1971). Animals will show aggression toward novel animals of the same sex, likely as a form of mate guarding behavior (Kleiman, 1977; Getz et al., 1981; Winslow et al., 1993; Carter et al., 1995). [2] In addition, there are some species that exhibit short-term monogamy which involves partnership termination while one's partner is still alive; however, it usually lasts for at least one breeding season. Am. Female space use is the best predictor of monogamy in mammals. Sci. Female distribution seems to be one of the best predictors of the evolution of monogamy in some species of mammals. Z., et al. Features of social monogamy and functional effects of associated peptide and steroid hormones (based on the prairie vole model). In both common usage and within the field of biology the term monogamy often infers sexual exclusivity either across the life-span or at a given point in time. J. Mammal. (2011). Because of the structural similarity between oxytocin and vasopressin, and their receptors, these peptides have many levels of interactions. Although there is consistency in the necessary ingredients, it is likely that there is no single recipe for social monogamy. Sci. Unlike other voles, prairie voles are generally monogamous. doi: 10.1016/S0306-4522(03)00555-4, Lonstein, J. S., Rood, B. D., and De Vries, G. J.

We are grateful to the National Science Foundation and National Institutes of Health, who for over 40 years have been the primary source of funding for this work, including most recently P01 HD075750 (CC) and F32 HD092051 (AP). Comparative analyses, especially in closely related yet behavioral distinct species, have been useful in identifying mechanisms through which evolutionary and proximate pressures could shape the features of social monogamy.

These features of social monogamy in mammals are supported by patterns of hormonal function originating in the neurobiology of maternity, including oxytocin, as well as a more primitive vasopressin pathway. doi: 10.1210/en.2004-1315, Lukas, D., and Clutton-Brock, T.

Furthermore, monogamous mating system and female dispersion are found to be closely related.
