关系思维，或者说表示事物之间关系的能力，在动物王国中很普遍。然而，人类进行推理和其他形式的抽象思维所需的高阶关系思维的能力是无与伦比的。在这里，我们提出，在人类中观察到的多功能推理技能可以追溯到外侧额顶网络（LFPN）的发育和进化变化。我们首先确定了 LFPN 中与关系思维联系最紧密的区域，并表明在发展过程中这些区域之间更强的沟通支持关系推理的改进。然后，我们探索人类和其他灵长类动物之间 LFPN 的差异，这可以解释关系推理能力的物种差异。我们得出的结论是，LFPN 特定区域及其连接中相当小的神经解剖学变化导致了认知的个体发生和系统发生的巨大变化。
Relational thinking, or the ability to represent the relations between items, is widespread in the animal kingdom. However, humans are unparalleled in their ability to engage in the higher-order relational thinking required for reasoning and other forms of abstract thought. Here we propose that the versatile reasoning skills observed in humans can be traced back to developmental and evolutionary changes in the lateral frontoparietal network (LFPN). We first identify the regions within the LFPN that are most strongly linked to relational thinking, and show that stronger communication between these regions over the course of development supports improvements in relational reasoning. We then explore differences in the LFPN between humans and other primate species that could explain species differences in the capacity for relational reasoning. We conclude that fairly small neuroanatomical changes in specific regions of the LFPN and their connections have led to big ontogenetic and phylogenetic changes in cognition.
