  8. Hamilton’s Rule Br > C (Beneficiary’s fitness)(relatedness) > (cost) In an Australian bird species called the superb fairy-wren, some breeding pairs have helpers and some do not. The baby birds of pairs with helpers get 20 percent more food than young fairy-wrens fed only by their parents, but curiously that gives them no long-term survival advantage. ~ the Washington Post
