This project aims to understand why so few biological traits scale proportionally with body size. In contrast to previous mechanistic studies of this longstanding question, the problem will be approached from an evolutionary viewpoint, using artificial selection to engineer animals in which biological scaling laws are either broken or enhanced. By measuring the consequences of this for fitness, the project will provide a new understanding of how organismal size and physiology evolve in nature. The approach should provide significant benefits to our understanding of the role of genetic constraints in hindering or facilitating biological adaptation, furthering our understanding of the capacity of animals to respond to environmental change.

该项目旨在了解为什么很少有生物特征与身体大小成比例。与以前对这个长期存在的问题的机械研究相反，这个问题将从进化的角度来处理，使用人工选择来设计生物尺度定律被打破或增强的动物。通过测量这对健康的影响，该项目将提供对生物体大小和生理学在自然界中如何进化的新理解。这种方法将为我们理解遗传限制在阻碍或促进生物适应方面的作用提供重大益处，进一步理解动物对环境变化的反应能力。
