Gamilaraay亲属关系的重新审视：隐性疾病的发生率是对合作行为的好处的动态权衡
Gamilaraay kinship revisited: incidence of recessive disease is dynamically traded-off against benefits of cooperative behaviours
摘要：
自19世纪中期以来，传统的土著婚姻规则得到了广泛的研究。尽管如此，它们在历史上一直被抛弃，因为它们几乎没有用处。这在很大程度上是由于人们专注于试图理解广泛的婚姻限制或它们可能如何演变。在这里，以Gamilaraay系统作为一个案例研究，我们而是问如何在这样一个系统下的相关性可能会分布。我们发现，值得注意的是，这个系统动态地权衡亲属回避，以尽量减少隐性疾病的发病率对预期的合作水平，正式理解通过汉密尔顿的规则。
英文摘要：
Traditional Indigenous marriage rules have been studied extensively since the mid 1800s. Despite this, they have historically been cast aside as having very little utility. This is, in large part, due to a focus on trying to understand broad-stroke marriage restrictions or how they may evolve. Here, taking the Gamilaraay system as a case study, we instead ask how relatedness may be distributed under such a system. We show, remarkably, that this system dynamically trades off kin avoidance to minimise incidence of recessive diseases against expected levels of cooperation, as understood formally through Hamilton's rule.
