符号交流的出现经常被认为是智人、语言和人类认知进化的关键一步。人们普遍假设人类是唯一拥有自然符号交流机制的物种，尽管其他物种可以被教导使用符号。符号交流的起源仍然是一个有争议的开放问题，由于缺乏化石记录而变得模糊。在这里，我们展示了一个完整的进化路径，从最初的非通信机器人的人口自发出现的符号通信。机器人在一个模拟的世界中进化，并且只有一个通信通道。当它们的繁殖能力是出于寻找配偶的需要时，在99%的实验中，机器人从最初不交流的种群中进化出索引通信方案。此外，9%的种群进化出一种符号通信方案，允许成对的机器人通过一维通道交换关于两个独立空间维度的信息，从而增加了它们繁殖的机会。这些结果表明，符号交流的能力可能是在自然选择下自发出现的，而不需要像以前所解释的那样，需要认知预适应或预先存在的图标交流方案。
The emergence of symbolic communication is often cited as a critical step in the evolution of Homo sapiens, language, and human-level cognition. It is a widely held assumption that humans are the only species that possess natural symbolic communication schemes, although a variety of other species can be taught to use symbols. The origin of symbolic communication remains a controversial open problem, obfuscated by the lack of a fossil record. Here we demonstrate an unbroken evolutionary pathway from a population of initially noncommunicating robots to the spontaneous emergence of symbolic communication. Robots evolve in a simulated world and are supplied with only a single channel of communication. When their ability to reproduce is motivated by the need to find a mate, robots evolve indexical communication schemes from initially noncommunicating populations in 99% of all experiments. Furthermore, 9% of the populations evolve a symbolic communication scheme allowing pairs of robots to exchange information about two independent spatial dimensions over a one-dimensional channel, thereby increasing their chance of reproduction. These results suggest that the ability for symbolic communication could have emerged spontaneously under natural selection, without requiring cognitive preadaptations or preexisting iconic communication schemes as previously conjectured.
