不同的大脑成分可以以协调的方式进化,也可以根据变异的马赛克模式显示出不同的进化轨迹。了解这些大脑进化模式之间的关系,这些模式不是相互排斥的,可以通过检查种内变异来了解。我们的研究评估了黑猩猩和人类大脑解剖共变的模式,以推断它们对古人类进化的影响。我们的研究表明,黑猩猩和人类的大脑都有一个模块化的结构,这可能促进了他们最后一个共同祖先的马赛克进化。空间相邻区域间的协变程度最强,分离区域间的相互独立性更强,这可能与局部关联连接优势有关。尽管发育和功能因素在决定脑形态方面的重要性毋庸置疑,但我们发现这些制约因素从属于局部空间相互作用的主要影响。
Different brain components can evolve in a coordinated fashion or they can show divergent evolutionary trajectories according to a mosaic pattern of variation. Understanding the relationship between these brain evolutionary patterns, which are not mutually exclusive, can be informed by the examination of intraspecific variation. Our study evaluates patterns of brain anatomical covariation in chimpanzees and humans to infer their influence on brain evolution in the hominin clade. We show that chimpanzee and human brains have a modular structure that may have facilitated mosaic evolution from their last common ancestor. Spatially adjacent regions covary with one another to the strongest degree and separated regions are more independent from each other, which might be related to a predominance of local association connectivity. Despite the undoubted importance of developmental and functional factors in determining brain morphology, we find that these constraints are subordinate to the primary effect of local spatial interactions.
