大脑是生物体性能和健康的核心重要特征。到目前为止，脑大小变化的进化研究主要是利用应用于物种或更高类群水平的比较方法。然而，这些研究遭受的困难，从相关性分离的因果关系。在另一个极端，大脑可塑性的研究主要集中在人口内的模式。在这两个极端之间是种群间的研究，重点是在同一物种的种群之间，占据不同的栖息地或选择制度的大脑大小的变化。这些研究形成了一个快速增长的研究领域，可以帮助我们通过为种间研究产生的想法提供测试平台来了解大脑进化，并有助于揭示遗传和环境因素对大脑大小和结构变化的相对重要性。除了提供第一次在深入审查已发表的种内研究的大脑大小的变化，我们讨论了嵌入的前景与人群间研究的大脑大小的变化。特别是，下列专题被确定为值得进一步注意：（i）研究重点是解开基因、环境及其相互作用对群体内和群体间大脑变异的贡献，（ii）研究应用定量遗传工具评估遗传和环境因素对不同个体发育阶段大脑特征的相对重要性，（iii）除了利用脑大小的简单粗略估计外，未来的研究可能受益于使用神经解剖学、神经组织学和/或分子方法来表征脑大小和结构的变化。大脑大小和结构的进化是一个广泛研究的主题。然而，大多数研究是种间的和比较的。在这里，我们总结了最近越来越多的种内研究的基础上人口比较，并概述了这种方法的未来潜力。
The brain is a trait of central importance for organismal performance and fitness. To date, evolutionary studies of brain size variation have mainly utilized comparative methods applied at the level of species or higher taxa. However, these studies suffer from the difficulty of separating causality from correlation. In the other extreme, studies of brain plasticity have focused mainly on within-population patterns. Between these extremes lie interpopulational studies, focusing on brain size variation among populations of the same species that occupy different habitats or selective regimes. These studies form a rapidly growing field of investigations which can help us to understand brain evolution by providing a test bed for ideas born out of interspecific studies, as well as aid in uncovering the relative importance of genetic and environmental factors shaping variation in brain size and architecture. Aside from providing the first in depth review of published intraspecific studies of brain size variation, we discuss the prospects embedded with interpopulational studies of brain size variation. In particular, the following topics are identified as deserving further attention: (i) studies focusing on disentangling the contributions of genes, environment, and their interactions on brain variation within and among populations, (ii) studies applying quantitative genetic tools to evaluate the relative importance of genetic and environmental factors on brain features at different ontogenetic stages, (iii) apart from utilizing simple gross estimates of brain size, future studies could benefit from use of neuroanatomical, neurohistological, and/or molecular methods in characterizing variation in brain size and architecture. Evolution of brain size and architecture is a widely studied topic. However, the majority of studies are interspecific and comparative. Here we summarize the recently growing body of intraspecific studies based on population comparisons and outline the future potential in this approach.
