Re:

Charlesworth and Charn=v published an age-structured theory of kin selection in 1981 (JTB 88:103)=and Taylor and Frank did it a different way in 1996 (JIB 180:27). I added =ime delays to the Charlesworth-Charnov model in 1993 (Evollutionary Ecolog= 7:406). These models all grow out of the ideas that Hamilton introduced i= his "Moulding of senescence" paper in 1966. But Hamilton 1966 d=dn't do kin selection. He did however argue that reproductive value is=not the right way to formulate the problem. His model (and also those ment=oned above) use the numerator of reproductive value, but the normalization=is different. To put this differently, the reproductive value at age x nee=s to be weighted by l_x, the probability of surviving to that age. This we=ghting is missing from the formulation directly in terms of reproductive v=lue.
