生命树的寿命有很大的不同。在对这一现象的各种解释中，涉及生殖和寿命之间权衡的解释获得了相当多的支持。有一个重要的例外：社会性昆虫繁殖（蚁后和白蚁中的国王）表现出高繁殖产量和非常长的寿命。由于缺乏生殖力/寿命权衡的最终和近似机制可以揭示延长寿命的意想不到的动态和分子机制，社会昆虫的生殖器在衰老研究领域引起了广泛的关注。在这里，我们强调当前的生态和生理研究老化和讨论各种可能的进化和分子解释的白蚁繁殖的延长寿命。我们将这些发现整合到一个连贯的框架中，揭示了这些繁殖动物寿命的演变。对白蚁的研究可以解释自然选择为什么以及如何塑造衰老。本文是主题问题“老龄化与社交性：社交性为何、何时以及如何改变老龄化模式？”的一部分。
Lifespan varies greatly across the tree of life. Of the various explanations for this phenomenon, those that involve trade-offs between reproduction and longevity have gained considerable support. There is an important exception: social insect reproductives (queens and in termites, also kings) exhibit both high reproductive outputs and extraordinarily long lives. As both the ultimate and proximate mechanisms underlying the absence of the fecundity/longevity trade-off could shed light on the unexpected dynamics and molecular mechanisms of extended longevity, reproductives of social insects have attracted much attention in the field of ageing research. Here, we highlight current ecological and physiological studies on ageing and discuss the various possible evolutionary and molecular explanations of the extended lifespans of termite reproductives. We integrate these findings into a coherent framework revealing the evolution of longevity in these reproductives. Studies on termites may explain why and how ageing is shaped by natural selection. This article is part of the theme issue ‘Ageing and sociality: why, when and how does sociality change ageing patterns?’
