Abstract

Human menopause remains an evolutionary puzzle as early termination of fertility does not seem adaptive. Cant and Johnstone (2008) proposed that intergenerational conflict in populations with female-biased dispersal can lead to the termination of fertility in females. One testable prediction from the intergenerational conflict model is that women should experience menopause earlier in groups with an evolutionary history of female-biased dispersal compared to groups with a history of male-biased dispersal. Using data from the Indonesia Family Life Survey on 2400 women aged 40-62 from 16 ethnic groups, we conducted a random effects discrete-time event history analysis of the progression to menopause by ethnic group postnuptial residence. We find no evidence that ethnic groups with a history of patrilocal residence have earlier age at menopause. In contrast, ethnic groups with a history of ambilocal residence have the slowest progression to menopause, while matrilocal and patrilocal ethnic groups have similar progression rates. These findings do not support the intergenerational conflict model and we discuss reasons why we may not expect genetically evolved solutions to intergenerational conflict.
