Dissertation Research: Evolution of Cooperation

迄今为止，关于合作演变的研究主要集中在 两个人之间的互动。 拟议的工作扩大 研究任何规模的群体合作的演变， 而不仅仅是两个大小的群体。 采用了两种方法。 1. 数学模型将允许预测 合作表现在不同规模的群体中。 2.一 涉及反捕食者行为群体的生物系统 将被用来测试数学模型。 在某些种类的 鱼，一小群人离开学校， 属于合作调查潜在危险 捕食者 该系统将允许操纵成本， 与合作有关的好处。 后续测试 将显示是否合作的程度预测 数学模型实际上是在自然界中表现出来的。

To date, studies on the evolution of cooperation have centered on interactions between two individuals. The proposed work expands the study of the evolution of cooperation to groups of any size, not just groups of size two. Two approaches are used. 1. Mathematical models will allow predictions of the amount of cooperation displayed in groups of various sizes. 2. A biological system which involves anti-predator behavior groups will be used to test the mathematical models. In some species of fish, a small group of individuals move away from the school they belong to and cooperatively investigate potentially dangerous predators. This system will allow manipulation of the costs and benefits associated with being cooperative. Subsequent testing will show whether the degree of cooperation predicted by mathematical models is, in fact, displayed in nature.
