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.
关系性思维，即表征事物之间关系的能力，在动物界广泛存在。然而，人类在进行推理和其他抽象思维形式所需的高阶关系性思维方面的能力是无与伦比的。在此，我们提出，人类所具备的多样推理技能可追溯到外侧额顶叶网络（LFPN）的发育和进化变化。我们首先确定LFPN中与关系性思维联系最紧密的区域，并表明在发育过程中这些区域之间更强的交流有助于关系性推理的提升。然后，我们探究人类与其他灵长类物种在LFPN上的差异，这些差异能够解释关系性推理能力的物种差异。我们得出结论，LFPN特定区域及其连接中相当小的神经解剖学变化已导致认知方面巨大的个体发育和系统发育变化。
