Description

Trade-offs are thought to be ubiquitous, come in different types, and have been at the heart of evolutionary biology, especially life-history theory.

Whether phenotypic or genetic, whether based on trait pairs or on a large number of traits or genes, the intuitive understanding of trade-offs might have often been too simplistic. This led to a dynamic field of research that often seems torn between having to elucidate some of the classic questions, for example whether there is a trade-off between reproduction and survival, and how it could affect evolutionary trajectories, and between newer methods, such as sequencing and gene editing. In this talk, I will highlight some fundamental questions on the effects of nutrition and sex-specific selection on the evolution of trade-offs that I have worked on. These case studies will span from empirical work on flies, to theoretical models. I will further discuss the potential of non-genetic transgenerational inheritance as a fairly new player in this line of research.

Dietary shifts—particularly the inclusion of animal resources—were pivotal in human evolution, yet direct evidence of meat consumption in early hominins remains limited and debated.
