Human evolution has been marked by a striking increase in total brain volume relative to body size. While a prominent and characteristic feature of this volumetric shift has been the disproportionate expansion of association cortex across our evolutionary lineage, descent with modification is apparent throughout all neural systems in both human and nonhuman primates. However, despite evidence for the ubiquitous and complex influence of evolutionary forces on brain biology, within the psychological sciences the vast majority of the literature on human brain evolution is entirely corticocentric. This selective focus has contributed to a flawed theoretical framework in which the evolution of association cortex is viewed as an isolated process, removed from the rest of the brain. Here, we review our current understanding of how evolutionary pressures have acted across anatomically and functionally coupled networks, highlighting the diverse set of rules and principles that govern human brain development. In doing so we challenge the systemic mischaracterization of human cognition and behavior as a competition that pits phylogenetically recent cortical territories against evolutionarily ancient subcortical and cerebellar systems. Rather, we propose a comprehensive view of human brain evolution with critical importance for the use of animal models, theory development, and network-focused approaches in the study of behavior across health and disease.

超越皮质:人类大脑的进化。

人类进化的标志是总脑容量相对于体型的显着增加。虽然这种体积变化的一个显着特征是联合皮层在我们的进化谱系中不成比例地扩展,但在人类和非人类灵长类动物的所有神经系统中,随着修改而下降是显而易见的。然而,尽管有证据表明进化力对大脑生物学的影响无处不在且复杂,但在心理科学中,绝大多数关于人类大脑进化的文献都是完全以皮质为中心的。这种选择性的关注导致了一个有缺陷的理论框架,在该框架中,联合皮层的进化被视为一个孤立的过程,与大脑的其余部分分离。这里,我们回顾了我们目前对进化压力如何在解剖学和功能耦合网络中发挥作用的理解,强调了支配人类大脑发育的各种规则和原则。在这样做的过程中,我们挑战了将人类认知和行为系统性错误描述为一种竞争,这种竞争将系统发育上最近的皮层区域与进化上古老的皮层下和小脑系统进行对比。相反,我们提出了人类大脑进化的综合观点,这对于在跨健康和疾病的行为研究中使用动物模型、理论发展和以网络为中心的方法至关重要。在这样做的过程中,我们挑战了将人类认知和行为系统性错误描述为一种竞争,这种竞争将系统发育上最近的皮层区域与进化上古老的皮层下和小脑系统进行对比。相反,我们提出了人类大脑进化的综合观点,这对于在跨健康和疾病的行为研究中使用动物模型、理论发展和以网络为中心的方法至关重要。在这样做的过程中,我们挑战了将人类认知和行为系统性错误描述为一种竞争,这种竞争将系统发育上最近的皮层区域与进化上古老的皮层下和小脑系统进行对比。相反,我们提出了人类大脑进化的综合观点,这对于在跨健康和疾病的行为研究中使用动物模型、理论发展和以网络为中心的方法至关重要。
