During the past 30 years, the evolution of endothermy has been a topic of keen interest to palaeontologists and evolutionary physiologists. While palaeontologists have found abundant Permian and Triassic fossils, suggesting important clues regarding the timing of origin of endothermy, physiologists have proposed several plausible hypotheses of how the metabolic elevation leading to endothermy could have occurred. More recently, molecular biologists have developed powerful tools to infer past adaptive processes, and gene expression mechanisms that describe the organization of genomes into phenotypes. Here, we argue that the evolution of endothermy could now be elucidated based on a joint, and perhaps unprecedented, effort of researchers from the fields of genomics, physiology and evolution.
在过去的 30 年中，温血动物的进化一直是古生物学家和进化生理学家非常感兴趣的话题。古生物学家发现了大量的二叠纪和三叠纪化石，这些化石为温血动物起源的时间提供了重要线索，而生理学家则提出了几种关于导致温血动物新陈代谢升高的合理假设。最近，分子生物学家开发了强大的工具来推断过去的适应过程，以及描述基因组组织成表型的基因表达机制。在这里，我们认为，温血动物的进化现在可以基于来自基因组学、生理学和进化领域的研究人员的联合研究来阐明，这也许是前所未有的。
