As a cooperative act decreases an individual's fitness for others to benefit, it is expected to be selected against by natural selection. That, how contrary to this naive expectation cooperation has evolved, is a fundamental problem in evolutionary biology and social sciences. Here, by introducing a mathematical model, we show that coevolution of cooperation and language can provide an avenue through which both cooperation and language evolve. In this model, individuals in a population play a prisoner's dilemma game and at the same time try to communicate a set of representations by producing signals. For this purpose, individuals try to build a common language, which is composed of a set of signal-representation associations. Individuals decide in language learning based on their payoff from the prisoner's dilemma game and decide about their strategy in the prisoner's dilemma game based on their success in conveying symbolic information. The model shows cooperators are able to build a common language and protect it against defectors' attempt to decode it. The language channels the benefit of cooperation toward cooperators, and defectors, being banished from the language, are unable to exploit cooperators, and are doomed to extinction.

合作与语言的共同进化
由于合作行为降低了个人对他人受益的适合度，因此预计会被自然选择选中。进化生物学和社会科学中的一个基本问题是，如何与这种天真的期望合作发展起来。在这里，通过引入一个数学模型，我们表明合作和语言的共同进化可以为合作和语言的进化提供一条途径。在这个模型中，群体中的个体玩囚徒困境游戏，同时尝试通过产生信号来交流一组表征。为此，个人试图建立一种共同语言，该语言由一组信号表示关联组成。个人根据他们从囚犯那里得到的回报来决定语言学习 的困境博弈，并根据他们在传达符号信息方面的成功来决定他们在囚徒困境博弈中的策略。该模型表明合作者能够构建一种通用语言并保护它免受叛逃者试图对其进行解码。语言将合作的利益传递给合作者，叛逃者被语言驱逐，无法剥削合作者，注定灭亡。
