[ 6, 17 ]), the reduced level of polygyny in agricultural populations typically characterized by greater inequality poses a serious challenge to existing models of mating and marriage. The polygyny threshold model (PTM) was developed by Orians in order to propose a hypothesis for the evolution of mating systems in birds and mammals based on individual fitness, and in opposition to a hypothesis based on group selection.Through the analyses of female choice possibilities, the PTM provides theoretical basis to predict the development of mating systems, specifically the shift . The model shows how females may gain a higher level of biological fitness by mating with a male who already has a mate. Age groups can be quite wide (for example, 'people under 50' or 'under 18s'). Introduction Until the 1960s, polygyny was largely considered a result of an excess of female to male breeders (Searcy and Yasukawa 1989 ).

Polygyny Threshold Model females pay a cost to mate with an already-mated male when they gain access to a better territory Cost of polygyny reduction in reproductive success when female mates with an already-mated male Polygyny Threshold the difference in territory quality that justifies paying the cost of polygyny 2. A. Polygyny should occur in patchy environments where males defend valuable resources B. The polygyny threshold model states that if costs incurred are less than the benefits gained from mating polygynously in terms of breeding-situation quality, then polygyny is favored and could evolve.

In this situation, the female has the option of breeding with an unmated male in a poor-quality territory or with an already-mated male in a high-quality territory. The polygyny threshold model illustrates the relationship between the territorial quality (or any breeding situation related to a specific available male) and female fitness.
