Understanding the relationship between gesture, sign, and speech offers a valuable tool for investigating how language emerges from a nonlinguistic state. We propose that the focus on linguistic status is problematic, and a shift to focus on the processes that shape these systems serves to explain the relationship between them and contributes to the central question of how language evolves.

手语出现的进化方法：从状态到过程

理解手势、手势和语音之间的关系为研究语言如何从非语言状态中出现提供了一个有价值的工具。我们认为，对语言地位的关注是有问题的，而将注意力转移到塑造这些系统的过程有助于解释它们之间的关系，并有助于解决语言如何演变的核心问题。
