As fond as we may be of our grandmothers, evolutionary biologists have long questioned why women live for so long after they can procreate. The so-called "grandmother hypothesis" posits that grandmothers help the species survive by taking care of grandchildren and helping support families. In the U.S., grandparents are the primary source of child care for a third of families with a working mother and young children. We discuss the role of grandmothers in the U.S. and globally. What role did your grandmother play in your life? If you're a grandmother, does your family rely on your labor? How do you feel about it?
