New pressure has been put on the models by the realization that small bodies spiral into the star on short timescales (in just a few hundred orbits). So here is their new idea: the pebbles just leaped over the size barrier. Chambers said, "Objects must have grown very rapidly from sub-metre-sized pebbles into 100-km-sized bodies, possibly in a single leap." That's just "Punctuated Equilibrium" for planets!
