Alan Stern is probably...

...one of very few experts on the formation of the Outer Solar System. His main point is that from the point of view of the current theories - including his own work - the inner System is oddly regular and under-populated. Beyond the Kuiper Belt, from the Scattered Disk to the Inner Oort there could be DOZENS of Mars - Earth-sized scattered remnants of the "oligarchs"/proto-planets that went into making the Gas Giants on highly-elliptical and inclined orbits.
