Kristen Hawkes' "Grandmother Hypothesis" provides a fascinating perspective on human evolution, menopause, and the unique social structures of humans. This theory posits that the long post-reproductive lifespan of women evolved because grandmothers played a critical role in supporting their descendants. By helping care for grandchildren and providing resources like food, grandmothers enhanced the survival and reproductive success of their families, which indirectly passed on their genes favouring longevity and cooperative behaviour. These contributions are thought to have driven distinct human traits, including increased brain size and social complexity, by encouraging intergenerational support and skill-sharing

Kristen Hawkes PhD MS BA examines foraging and social strategies among hunter-gatherers to shed light on human evolution. Her work includes three projects focused on life history evolution, aging in captive chimpanzees, and understanding fire’s effects on foraging payoffs, all informed by ethnographic studies of the Ache in Paraguay and the Hadza in Tanzania. Observations suggest that men’s hunting primarily serves status competition rather than provisioning, while grandmothers play a crucial role in supporting their grandchildren, especially when mothers have more children. This aligns with the grandmother hypothesis, which explains human longevity and highlights differences between humans and chimpanzees, such as longer lifespans despite similar fertility rates and a male-biased sex ratio. Mathematical modeling underscores the impact of grandmothering on post-menopausal longevity, shorter birth intervals, and social behavior. Kristen Hawkes continues to collaborate on data collection and analysis to enhance understanding of ancestral foraging strategies and aging in captive chimpanzees.
