This chapter addresses two issues in which molecular analyses are important for our understanding of life history evolution. First, information on the genomic regulation of trade-offs – a central assumption of life history theory and evolutionary theory in general – promises to facilitate the production of mechanistic models of trade-offs, which may contribute to the development of theories that combine quantitative genetic and mechanistic approaches. Second, genomic analyses can address the question of the extent to which evolutionary trajectories are deterministic versus stochastic (the ‘skinning the cat problem’). In this regard, the chapter presents an experimental framework within which to investigate this problem.
