This project aims to dissect the complex costs of reproduction, bridging an old divide between evolutionary and biomedical approaches to understanding ageing and lifespan. Merely detecting the smell of another individual, without ever encountering them, can cause an individual to mature sooner, age faster, or live a shorter life. These costs, and the fact that subsequent mating can restore adult ageing and lifespan to "normal" are causing a re-evaluation of the costs of reproduction - an important but enigmatic concept in evolution. This project expects to resolve how and why the physical presence of a mate, or odour cues of such a mate, can have such dramatic effects on ageing and late-life performance.

该项目旨在剖析繁殖的复杂成本，弥合进化和生物医学方法之间的旧鸿沟，以了解衰老和寿命。仅仅是察觉到另一个人的气味，而从来没有遇到过他们，就可以使一个人更快地成熟，更快地衰老，或者活得更短。这些成本，以及随后的交配可以将成年人的衰老和寿命恢复到“正常”的事实，导致了对生殖成本的重新评估--这是进化中一个重要但神秘的概念。这个项目希望解决如何以及为什么配偶的身体存在或气味线索会对衰老和晚年表现产生如此戏剧性的影响。
