脊椎动物的大脑在解剖学上表现出巨大的多样性。特别是，复杂的神经系统与它们的行为库的大小相关。然而，物种特异性脑形态发生的进化机制仍然难以捉摸。在这篇综述中，我们介绍了爬行动物作为一种新的模式生物，了解大脑的进化。这些动物群体继承了祖先的大脑结构特征。我们将描述爬行动物神经系统的几个独特的方面，特别关注端脑，并讨论爬行动物特有的大脑形态的遗传机制。研究爬行动物的实验性evo-devo方法的建立将有助于阐明爬行动物大脑的起源。
Vertebrate brains exhibit vast amounts of anatomical diversity. In particular, the elaborate and complex nervous system of amniotes is correlated with the size of their behavioral repertoire. However, the evolutionary mechanisms underlying species-specific brain morphogenesis remain elusive. In this review we introduce reptiles as a new model organism for understanding brain evolution. These animal groups inherited ancestral traits of brain architectures. We will describe several unique aspects of the reptilian nervous system with a special focus on the telencephalon, and discuss the genetic mechanisms underlying reptile-specific brain morphology. The establishment of experimental evo-devo approaches to studying reptiles will help to shed light on the origin of the amniote brains.
