text: (2007) and Bowles and Gintis (2011) note, if altruism is defined by reference to lifetime fitness, then Trivers' theory is not really about the evolution of altruism at all; for behaviours that evolve via reciprocation of benefits, as described by Trivers, are ultimately of direct benefit to the individuals performing them, so do not reduce lifetime fitness.
