人类大脑的认知能力,包括语言,在我们最近从非人类灵长类动物进化的过程中急剧扩展,尽管在基因水平上只有微小的明显变化。我们为这个悖论提出的假设依赖于人类大脑连接的基本特征,这些特征有助于形成特征性的解剖学、功能和计算神经表型,为在人类特定的基因组进化中发生的连接组学变化提供了一个简约的框架。许多人类的连接组学特征可能是由于灵长类大脑的整体神经结构中大脑尺寸的大幅增加,导致大量的神经元和区域以及稀疏化,模块化增加和皮层连接的层状分化。这些特征与上皮层的发育扩展、出生后大脑发育的延长以及与物理、社会和文化环境的多重非遗传相互作用相结合,产生了人类特有的认知能力,包括语言的递归性。因此,一小部分影响定量基因表达的遗传调控事件可能解释了人类大脑连接和认知的起源。
Cognitive abilities of the human brain, including language, have expanded dramatically in the course of our recent evolution from nonhuman primates, despite only minor apparent changes at the gene level. The hypothesis we propose for this paradox relies upon fundamental features of human brain connectivity, which contribute to a characteristic anatomical, functional, and computational neural phenotype, offering a parsimonious framework for connectomic changes taking place upon the human-specific evolution of the genome. Many human connectomic features might be accounted for by substantially increased brain size within the global neural architecture of the primate brain, resulting in a larger number of neurons and areas and the sparsification, increased modularity, and laminar differentiation of cortical connections. The combination of these features with the developmental expansion of upper cortical layers, prolonged postnatal brain development, and multiplied nongenetic interactions with the physical, social, and cultural environment gives rise to categorically human-specific cognitive abilities including the recursivity of language. Thus, a small set of genetic regulatory events affecting quantitative gene expression may plausibly account for the origins of human brain connectivity and cognition.
