尽管人们对一夫一妻制在不同分类群中的进化和影响很感兴趣,但人们对理解离婚的进化(结束社会上的一夫一妻制以寻找新的伴侣)的关注较少,尤其是在理论上。在这里,我们开发了一个模型,在一个异质的环境中,女性根据自己的生育成功来评估领地质量。离婚导致女性不成比例地离开贫穷地区而不是好地区,而配偶的死亡与领土质量无关,这给离婚带来了优势。环境异质性增加,结对经验带来的好处减少,适中的存活率有利于更高离婚率的演变,即使在个人素质和对可用地区的了解没有差异的情况下也是如此。关于领土质量的不完善信息限制了离婚的演变,通常倾向于在成功繁殖时保持对伴侣忠诚的离婚策略。我们的模型显示了离婚、丧偶和领地可获得性之间的反馈如何在决定离婚的进化优势时错综复杂地联系在一起。我们详细介绍了关于预计高离婚率的人口的可测试预测。
Despite widespread interest in the evolution and implications of monogamy across taxa, less attention—especially theoretical—has been paid toward understanding the evolution of divorce (ending a socially monogamous pairing to find a new partner). Here, we develop a model of the evolution of divorce by females in a heterogeneous environment, where females assess territory quality as a result of their breeding success. Divorce results in females leaving poor territories disproportionally more often than good territories, while death of a partner occurs independent of territory quality, giving an advantage to divorce. Increasing environmental heterogeneity, a decreasing benefit of pair experience, and moderate survival rates favor the evolution of higher divorce rates, even in the absence of variance in individual quality and knowledge of available territories. Imperfect information about territory quality constrains the evolution of divorce, typically favoring divorce strategies that remain faithful to one’s partner whenever successful reproduction occurs. Our model shows how feedbacks between divorce, widowhood, and the availability of territories are intricately linked in determining the evolutionary advantage of divorce. We detail testable predictions about populations that should be expected to divorce at high rates.
