Evolutionary psychology's notion of differential grandparental investment and the Dodo Bird Phenomenon: Not everyone can be right

  • Martin Voracek (a1), Ulrich S. Tran (a2) and Maryanne L. Fisher (a3)

Integration of different lines of research concerning grandparental investment appears to be both promising and necessary. However, it must stop short when confronted with incommensurate arguments and hypotheses, either within or between disciplines. Further, some hypotheses have less plausibility and veridicality than others. This point is illustrated with results that conflict previous conclusions from evolutionary psychology about differential grandparental investment.
