新陈代谢是衡量行为能量成本的指标，在社会进化中发挥着重要作用。体型和代谢规模是耦合的，体型增加的社会生态模式与饮食变化和更大、更复杂群体的形成有关。动物社会适应性辐射的这些后果引发了有关能量消耗的问题，其中很大一部分可能涉及处理社会信息的大脑的代谢率。大脑的大小随着身体的大小而变化，但人们对大脑代谢的变化知之甚少。蚂蚁等社会性昆虫在工蚁的身体大小和形态上表现出很大的差异，这与大脑的大小、结构和工蚁的任务表现相关，而这取决于感官输入和产生行为的信息处理能力。工人生产和维护成本的升高可能会对身体尺寸和大脑尺寸施加能量限制，这反映在代谢规模的模式中。大脑进化模型并不能清楚地预测大脑代谢规模的模式，也没有具体说明其与任务绩效和工人人体工程学效率（蚂蚁社会进化的两个关键要素）的关系。大脑代谢率很少被记录，因此，大脑代谢影响大脑大小演变的条件尚不清楚。我们建议，形态进化、群体社会组织和工人人体工程学效率的研究应与对大脑代谢尺度的物种特异性模式的分析相结合，以增进我们对蚂蚁大脑进化的理解。
Metabolism, a metric of the energy cost of behavior, plays a significant role in social evolution. Body size and metabolic scaling are coupled, and a socioecological pattern of increased body size is associated with dietary change and the formation of larger and more complex groups. These consequences of the adaptive radiation of animal societies beg questions concerning energy expenses, a substantial portion of which may involve the metabolic rates of brains that process social information. Brain size scales with body size, but little is understood about brain metabolic scaling. Social insects such as ants show wide variation in worker body size and morphology that correlates with brain size, structure, and worker task performance, which is dependent on sensory inputs and information-processing ability to generate behavior. Elevated production and maintenance costs in workers may impose energetic constraints on body size and brain size that are reflected in patterns of metabolic scaling. Models of brain evolution do not clearly predict patterns of brain metabolic scaling, nor do they specify its relationship to task performance and worker ergonomic efficiency, two key elements of social evolution in ants. Brain metabolic rate is rarely recorded and, therefore, the conditions under which brain metabolism influences the evolution of brain size are unclear. We propose that studies of morphological evolution, colony social organization, and worker ergonomic efficiency should be integrated with analyses of species-specific patterns of brain metabolic scaling to advance our understanding of brain evolution in ants.
