Contradicting new dual-pathway models of language evolution, cortico-striatal-thalamic circuitry disambiguate uncertainties in affective prosody and propositional linguistic content of language production and comprehension, predictably setting limits on useful complexity of articulate phonic and/or signed speech. Such limits likely evolved to ensure public information is discriminated by intended communicants and safeguarded against the ecological pressures of social eavesdropping within and across phylogenetic boundaries.
与新的语言进化双通路模型相反,皮质-纹状体-丘脑回路消除了情感韵律和语言产生和理解的命题语言内容的不确定性,可预测地限制了清晰的语音和/或手语的有用复杂性。这些限制可能是为了确保信息被意图的交流者区分,并防止在种内和种间的生态压力下被社会偷听而进化的。
