Evolutionary Anthropology 43 ARTICLES Menopause: Adaptation or Epiphenomenon?
Menopause is a nonfacultative and irreversible cessation of fertility that occurs in all female conspecifics well before the senescence of other somatic systems and the end of the average adult life span (Fig. 1). 1–3 So defined, menopause occurs only in humans and one species of toothed whales. 1–4...
