Life-history theory predicts a trade-off between early-life fitness and
life span. While the focus traditionally has been on the fecundity-life
span trade-off, there are strong reasons to expect trade-offs with growth
rate and/or development time. We investigated the roles of growth rate and
development time in the evolution of life span in two independent
selection experiments in the outcrossing nematode Caenorhabditis remanei.
First, we found that selection under heat-shock leads to the evolution of
increased life span without fecundity costs, but at the cost of slower
development. Thereafter, the putative evolutionary links between
development time, growth rate, fecundity, heat-shock resistance and life
span were independently assessed in the second experiment by directly
selecting for fast or slow development. This experiment confirmed our
initial findings, since selection for slow development resulted in the
evolution of long life span and increased heat-shock resistance. Because
there were no consistent trade-offs with growth rate or fecundity, our
results highlight the key role of development rate – differentiation of
the somatic cells per unit of time – in the evolution of life span. Since
development time is under strong selection in nature, reduced somatic
maintenance resulting in shorter life span may be a widespread cost of
rapid development.
