Recent empirical evidence suggest that trade-off relationships can evolve,
challenging the classical image of their high entrenchment. For energy
reliant traits, this relationship should depend on the endocrine system
that regulates resource allocation. Here we model changes in this system
by mutating the expression and conformation of its constitutive hormones
and receptors. We show that the shape of trade-offs can indeed evolve in
this model through the combined action of genetic drift and selection,
such that their evolutionarily expected curvature and length depend on
context. In particular, the shape of a trade- off should depend on the
cost associated with resource storage, itself depending on the traded
resource and on the ecological context. Despite this convergence at the
phenotypic level, we show that a variety of physiological mechanisms may
evolve in similar simulations, suggesting redundancy at the genetic level.
This model should provide a useful framework to interpret and unify the
overly complex observations of evolutionary endocrinology and evolutionary
ecology.
