The upper set of lines is for simulations where helping often produces large benefits (b = 4–12), and the lower set is for simulations where helping has moderate benefits (b = 3–9). No sociality results under conditions where helping provides poor benefits (b = 2–6). Lines in each set represent 1, 3, 7, 11, or 15 loci and are shown for only the first 1,000 generations of the simulation.
