Factors and you can Consequences off Monogamy
The human being life record trend (we.elizabeth., brief delivery periods, relatively higher child success, and you will years from teenager dependency) ensures that moms and dads are usually about reputation out-of support numerous dependents of several many years concurrently. Due to the fact babies, juveniles, and you can teens for each and every want different types of efforts investments, mothers try presented that have an allowance condition while in the most of the reproductive community: just how to look after infants and young children instead reducing time spent into the circumstances that give food and most other tips to possess older pupils (Lancaster, 1991; Hurtado et al., 1992; Hrdy, 1999; Kaplan et al., 2000; Kramer, 2005b, 2010; Kramer and Veile, 2018). Exactly how mothers manage so it exchange-off to support an abrupt reproductive rate has long been theoretically linked with monogamy as well as the cooperation out of dads, siblings, while some to aid mothers raise dependents.
Cooperative Breeding
, 2014), which in introduction to male parental financing, is a button determining facet of human sociality, cognition, and you can market victory (Hrdy, 2005, 2009; Kramer, 2010; van Schaik and you may Burkart, 2010; Kramer and you will Greaves, 2011). Multiple previous phylogenetic analyses promote powerful evidence you to definitely collaborative reproduction for the bird, insect, and you will mammalian taxa was preceded from the an origin out of monogamy (Hughes mais aussi al., 2008; Cornwallis mais aussi al., 2010; Lukas and you will Clutton-Brock, 2012). The reason is that into the a low-monogamous mating system, a good sexually mature individual may be a lot more directly related to his very own offspring (r = 0.5) rather than sisters that has yet another phrendly moms and dad (r between siblings = 0.25).
