The Ants Say: Pareto Was Wrong

I've always believed the Pareto 80/20 rule had broad applicability.  But now scientists report it's even broader than I knew, but Pareto had the numbers wrong--it's really 70/30.  It turns out 70 percent of ants let the others do the digging of tunnels, which is important because otherwise you violate the "too many cooks in the kitchen" rule--the extra workers just run into each other.
