语言产生于生物进化、学习和文化这三个复杂的适应系统的相互作用。我们在这里关注文化进化，并提出了一个关于构成性出现的迭代学习模型，构成性是语言的一个基本结构属性。我们的主要结果是，语言学习者可获得的刺激的匮乏导致了语言结构的压力。当文化传播出现瓶颈时，只有从稀疏输入数据中可以概括的语言才是稳定的。语言本身是在文化时间尺度上进化的，而合成性是语言对刺激贫乏的适应。
Language arises from the interaction of three complex adaptive systems — biological evolution, learning, and culture. We focus here on cultural evolution, and present an Iterated Learning Model of the emergence of compositionality, a fundamental structural property of language. Our main result is to show that the poverty of the stimulus available to language learners leads to a pressure for linguistic structure. When there is a bottleneck on cultural transmission, only a language which is generalizable from sparse input data is stable. Language itself evolves on a cultural time-scale, and compositionality is language's adaptation to stimulus poverty.
