The thing that made the modern differential a reality was the ability to cut hypoid gears (ring and pinion gears) cheaply. That allowed the drive shaft to impart its power at the bottom of the ring gear instead of ion the middle, thereby lowering the drive shaft.

The Antikethyra Mechanism, an ancient Greek astronomical computer found in 1901, used differential gears nearly 2,000 years before we developed them.
