Life History Variable

Characteristic of the growth and development of an organism such as the length of gestation, degree of dependency at birth, timing of the tooth eruption sequence (in dentates), timing of sexual maturity, length of reproductive period, and maximum lifespan potential, among others. In current models of hominid life history reconstruction, one (or more) of these variables is a candidate(s) for the cause of hominid behavioral adaptations.

Cf. the man the hunter hypothesis. Aka life history parameter.
