将动物行为置于进化论的背景下是上世纪生物学家的伟大成就之一。生活史理论在解释表型进化中的适应和限制方面是一个强有力的工具，但很少涉及它所讨论的性状的机械基础。分子生物学的最新进展已经开始揭示这些机制，并提供了一个挑战的传统观点，生活史的权衡是有限资源的差异分配的结果。特别是，秀丽隐杆线虫的繁殖成本似乎来自分子信号，这被认为是任意的健身。我们回顾了C.秀丽线虫不是以资源为基础的，并发现这并不一定是事实。然而，我们欢迎对传统思维的挑战，并建议将对机制的理解整合到生活史理论中将是21世纪世纪进化生物学家面临的最令人兴奋的任务之一。(C)2003年由爱思唯尔有限公司代表动物行为研究协会出版。
The placing of animal behaviour in an evolutionary context is one of the great achievements of biologists in the last century. Life history theory has been a powerful tool in explaining both adaptation and constraint in phenotypic evolution, but rarely addresses the mechanistic bases of the traits it discusses. Recent advances in molecular biology have begun to uncover these mechanisms, and provide a challenge to the traditional view that life history trade-offs are the result of the differential allocation of limiting resources. In particular, costs of reproduction in Caenorhabditis elegans appear to arise from molecular signals, which have been claimed to be arbitrary with respect to fitness. We review the evidence that costs of reproduction in C. elegans are not resource based, and find that this is not necessarily the case. However, we welcome the challenge to traditional thinking, and suggest that integrating an understanding of mechanisms into life history theory will be one of the most exciting tasks facing evolutionary biologists in the 21st century.
