Document Summary

1. all societies have some form of pair bond- male and female. 3. these pair bonds are preferred for child rearing. Male perceptive : this is practically a no brainer - Female- become a second wife if that is more bene cial than marrying the available single men (want children to be in better marriage) Polygyny threshold model - predicts that poly is more likely when there is much variance in male quality. When the difference among males pass a certain threshold. Would rather become the second wife of a hot, higher quality guy then be the rst wife of an ugly low quality guy. Polygyny threshold - point at which it pays females to mate polygynously - and to become the second wife. Omega male- last guy in society produces 100 units of food- being rst wife, you get to share this food, if you are a second wife, you share equally with all of there wives.
