Before revision:  We determine how the evolution depends on the number of replicating components per collective (N) and the mutation rate of replicating components (m)  such that evolution becomes increasingly independent of m as s decreases (i.e., \alpha}\downarrow0 \downarrow0 .
After revision:  We determine how the evolution depends on the number of replicating components per collective (N) and the mutation rate of replicating components (m) , and selection strength (s). We find that decreasing N or m promotes evolution toward altruism, and if this evolution is exactly balanced out by evolution towards selfishness, N and m satisfy a scaling relation N\,\propto\, m^{-\alpha such that evolution becomes increasingly independent of m as s decreases (i.e., \alpha}\downarrow0 \downarrow0 .
