Comparison of primate life history trajectories. Lifespan ranges represent maximum observed longevities in the wild and in captivity. Maximum human longevity is given as 100 years to compensate for the vast difference in amount of longevity data between humans and other primates. Only about one to two of 10,000 humans live as long as 100 years in modern industrialized populations. Marmoset common marmoset (C. jacchus), lemur gray mouse lemur (M. murinus). Note that marmosets and lemurs do not have menstrual cycles (they have estrous cycles), thus do not have menopause
