Despite the central importance of ageing in our own lives, our understanding of the evolution of ageing is still incomplete. Reproductive interests of males and females often diverge, resulting in sexual conflict which may in turn drive the evolution of rapid ageing. I will use experimental evolution to investigate the role of sexual conflict in the evolution of age-specific mortality, reproductive ageing and lifespan in the seed beetle Callosobruchus maculates. This study will reveal the role of sexual interactions and reproduction in the ageing process and result in the development of important new resources for resolving the genetic basis of deteriorative ageing.

尽管老龄化在我们自己的生活中至关重要，但我们对老龄化演变的理解仍然不完整。男性和女性的生殖利益往往不同，导致性冲突，这可能反过来推动迅速老龄化的演变。我将使用实验进化来研究性冲突在种子甲虫Callosobruchus maculates的年龄特异性死亡率、生殖衰老和寿命进化中的作用。这项研究将揭示性互动和生殖在衰老过程中的作用，并为解决衰老恶化的遗传基础开发重要的新资源。
