Quick Reference

A theory holding that many physiological and behavioural traits can best be understood in the context of the major characteristics that define the life history of the individual. Such events include the age at which the young become independent, the age at which individuals reach sexual maturity, age at first reproduction, gestation period, litter size, interval between reproduction, and adult body size. The allocation to these involves evolutionary trade-offs that permit comparisons between species, often using a Darwinian demon as a base for comparisons.
