I wonder if they still wouldn’t have invented the wheel yet.
Note however that the sub-saharan africans DID invent the wheel on their own before Christ but it was used primarily as the potters wheel - and why?
Because they did not have any draught animals (the same reason meso-America did not develop the wheel). The cow came to East Africa through the Arabs who also brought the wheel. But without draught animals, inventing a wheel would be longer
