“…dispersion and ecological variation in relation to the evolution of both living and fossil primates. [3][4][5][6][7][8][9] The estimated life expectancy of these animals in conditions of captivity is 30 years, 10 a fact that facilitates ontogenic studies and the determination of specific, age-dependent physiological processes. It is well known that various biological functions, including behavior, cognition, locomotion, posture, mastication, the search for food and ingestion, reproduction and sociability change during ontogeny in a developmental process that seems to follow a lineal order correlated with corporal growth.…”
