Document Summary
Concerns the evolutionary forces that shape the timing of life events involved in development, growth, reproduction, and aging. How an organism allocates its limited supply of energy. Life history traits are subject to natural selection just as anatomical, biochemical, and behavioral traits. We expect selection to lead organisms to allocate their energy optimally within the contraints they face. Examples of life history trait variation (dont need to memorize) Three trade-offs in lh evolution: energy allocated to . Collapses to a trade-off between investment in future reproduction (growth+ maintenance = somatic effort) and investment in current reproduction (=reproductive effort) During juevenile phases all energy is invested in future reproduction. Semelparity is the full allocation of energy to current reproduction, followed by immediately by death. Life history theory can help to explanin why deterioration leading to death happens. Senescence as a puzzle, and one discredited solution.
