我们研究的词汇和句法歧义从进化的角度来看，在前额叶脑的顺序和组合的关系和词序的演变，这些歧义的决议。我们发现，SVO句中动词后存在时间歧义，这导致了额下回的激活，而SOV句中没有激活。这暗示人类语言最早演化出SOV语序。然后，我们证明，名词性后关系从句演变从意合从句与非关系化共享NP。嵌入是通过将中心名词拉到关系分句之前的位置来进行的，以避免中心嵌入引起的知觉歧义，因为中心嵌入需要我们太多的短期记忆。这也导致了从OV到VO的语序变化。语言进化过程以避免词汇和句法歧义。它不是专门的词汇或句法，而是一种普遍的认知倾向，试图解决歧义，或避免左额下回的工作记忆负担。
We examine the lexical and syntactic ambiguities from an evolutionary perspective of sequential and combinatorial relationships in the prefrontal brain and the evolution of word order as resolution of these ambiguities. We find that there is temporal ambiguity after the verb in SVO sentences, which causes the activation of the inferior frontal gyrus, while there is no activation in SOV sentences. This implicates the earliest human language evolved the SOV word order. We then demonstrate that the postnominal relative clause evolved from the paratactic clause with a non-relativized shared NP. Embedding took place by pulling the head noun to a position before the relative clause to avoid perceptual ambiguity arising from center-embedding which demands too much of our short-term memory. This also produced the word order change from OV to VO. Language evolves procedures to avoid lexical and syntactic ambiguities. It is not specifically lexical or syntactic, but a general cognitive tendency to attempt to resolve ambiguity, or to avoid the burden on working memory in the left inferior frontal gyrus.
