语言的起源是地球上生命最重要的进化里程碑之一，但也是最持久的科学未知之一。二十年前，博弈论家和数学家预测，第一个单词和语法的出现是对语言前体系统中的传输错误和信息丢失的回应，然而，缺乏经验证据。在这里，我们评估了信息损失的原辅音和原元音在人类前语言的祖先作为代理的猩猩辅音和元音样的电话，组成音节样的组合。我们回放并重新记录了在结构复杂的栖息地（即不利于声音传播）中距离越来越远的呼叫。辅音样和元音样的电话降级声学距离，但没有检测到信息损失的三个不同类别的信息（即个人ID，上下文和人口ID）。我们的研究结果反驳了流行的数学预测，并预示着语言进化理论和语言学的转折点。也就是说，解释原始人类家族中的声音-言语连续体是如何交叉的，将受益于未来的数学和计算模型，为了享受经验的有效性和上级解释力，这些模型将被大猿的行为和剧目所告知。
The origin of language is one of the most significant evolutionary milestones of life on Earth, but one of the most persevering scientific unknowns. Two decades ago, game theorists and mathematicians predicted that the first words and grammar emerged as a response to transmission errors and information loss in language's precursor system, however, empirical proof is lacking. Here, we assessed information loss in proto-consonants and proto-vowels in human pre-linguistic ancestors as proxied by orangutan consonant-like and vowel-like calls that compose syllable-like combinations. We played back and re-recorded calls at increasing distances across a structurally complex habitat (i.e. adverse to sound transmission). Consonant-like and vowel-like calls degraded acoustically over distance, but no information loss was detected regarding three distinct classes of information (viz. individual ID, context and population ID). Our results refute prevailing mathematical predictions and herald a turning point in language evolution theory and heuristics. Namely, explaining how the vocal–verbal continuum was crossed in the hominid family will benefit from future mathematical and computational models that, in order to enjoy empirical validity and superior explanatory power, will be informed by great ape behaviour and repertoire.
