Cerebral lateralization and associated motor behaviors were historically thought to be characteristics unique to humans. Today, it is clear that these features are present and visible in other animal species. These shared attributes of brain and behavior suggest inheritance from a distant common ancestor. Population-level motor biases are likely to reflect an early evolutionary division of primary survival functions of the brain's left and right hemispheres. In modern humans, these features may provide a foundational platform for the development of higher cognitive functions, inextricably cementing the ties between the evolution and development of cognition. This chapter focuses on the links between a vertebrate-wide right hemisphere dominance for perceiving and producing social signals, left side motor biases (inclusive of visual field preferences), and the evolution and development of cognition in modern humans.
大脑的侧化及相关运动行为在历史上被认为是人类独有的特征。如今，很明显这些特征在其他动物物种中也存在且可见。大脑和行为的这些共同属性表明它们继承自一个遥远的共同祖先。群体水平的运动偏向可能反映了大脑左右半球主要生存功能的早期进化分工。在现代人类中，这些特征可能为更高认知功能的发展提供一个基础平台，将认知的进化与发展之间的联系紧密地结合在一起。本章重点关注在整个脊椎动物范围内右半球在感知和产生社会信号方面的优势、左侧运动偏向（包括视野偏好）以及现代人类认知的进化与发展之间的联系。
