Using behavior to determine immature life-stages in captive western gorillas
Ontogenic development is divided into infant, juvenile, adolescent and adult life-stages. Although the developmental trajectory of an individual is a flexible entity, which differs within species, environment and sex, life-stage classifications are generally structured, age-based systems.

In rhesus monkeys, […]
