Human groups tend to be much larger than those of non-human primates. This is a puzzle. When ecological factors do not limit primate group size, the problem of coordination creates an upper threshold even when cooperation is guaranteed. This paper offers a model of group coordination towards behavioural synchrony to spell out the mechanics of group size limits, and thus shows why it is odd that humans live in large societies. The findings suggest that many of our species' evolved social behaviours and culturally maintained social technologies emerged as solutions to this problem.
人类群体往往比非人类灵长类动物的群体大得多。这是一个谜题。当生态因素不限制灵长类动物的群体大小时，即使合作有保障，协调问题也会产生一个上限。本文提供了一个关于群体协调以实现行为同步的模型，以阐明群体规模限制的机制，从而说明为什么人类生活在大型社会中是奇怪的。研究结果表明，我们物种许多进化而来的社会行为和文化维系的社会技术都是作为解决这个问题的方案而出现的。
