Grandparental investment can be basically defined as any contribution directed toward grandchildren by grandparents. Grandparental investment can include emotional support, physical care, and financial aid, and may also be indirect (e.g., through supporting the grandchildren’s parents). Typically, there are costs associated with grandparental investment (e.g., time or money), which are dependent on the nature of the investment. From an evolutionary perspective, grandparents are predicted to gain indirect fitness (i.e., ensuring the proliferation of their genes) from grandparental investment, either through increasing the number of grandchildren by investing in their adult children to increase fertility or by increasing the well-being and survival of their grandchildren.
Introduction
Grandparental investment is determined by the length of time grandparents are simultaneously alive with their...
