1. Early homosapiens realised that round objects could be easily moved by rolling them.
2. Their descendants advanced this rolling technique into the transportation of large objects on cylindrical logs.
3. The invention of the wheel and axle allowed a rolling log to be placed through a hole in a wheel to create a cart.
4. Chariot racing was influential in the evolution of the spoked wheel as they allowed chariots to move much faster.
5. The invention of air filled rubber tyres allowed wheels to be much faster, sturdier and stronger
