 Obiettivo del progetto (Objective)

Sex differences in life span and aging are ubiquitous across the animal kingdom and represent a long-standing challenge in evolutionary biology. In most species, including humans, sexes differ not only in how long they live and when they start to senesce, but also in how they react to environmental interventions aimed at prolonging their life span or decelerating the onset of aging. Therefore, sex differences in life span and aging have important implications beyond the questions posed by fundamental science. Both evolutionary reasons and medical implications of sex differences in demographic, reproductive and physiological senescence are and will be crucial targets of present and future research in the biology of aging. Here I propose a two-step approach that can provide a significant breakthrough in our understanding of the biological basis of sex differences in aging. First, I propose to resolve the age-old conundrum regarding the role of sexspecific mortality rate in sex differences in aging by developing a series of targeted experimental evolution studies in a novel model organism – the nematode, Caenorhabditis remanei. Second, I address the role of intra-locus sexual conflict in the evolution of aging by combining novel methodology from nutritional ecology – the Geometric Framework – with artificial selection approach using the cricket Teleogryllus commodus and the fruitfly Drosophila melanogaster. I will directly test the hypothesis that intra-locus sexual conflict mediates aging by restricting the adaptive evolution of diet choice. By combining techniques from evolutionary biology and nutritional ecology, this proposal will raise EU’s profile in integrative research, and contribute to the training of young scientists in this rapidly developing field.
