    According to a few sources ("George Price's Contributions to Evolutionary Genetics" for example) state that using the Price equation of Hamilton's work on kin selection one can predict the evolution of spite if an individual (or a gene) is negatively related to another. But what does that mean? How can you be negatively related to someone?

    I think I figured it out (sort of).

    The r in C<rB is not always relatedness, at least when Himilton's rule is derived from Price's equation.

    r = Cov(g,g')/Var(g) where g is the value of altruism in the individual and g' is the altruism of its neighbors. This r can be negative and does not always imply relatedness (although it often does).
