The wheel was independently invented in only two regions
The wheel was invented in the 4th millennium BC in Lower Mesopotamia (modern-day Iraq). The earliest evidence of wheels in India, for example, dates back 4,500 years. The wheel didn't reach Europe until 3,000 years ago. In the Old World, one of the last peoples to adopt the wheel was the British, just 2,500 years ago. While Europe was late to the party, Mesoamerica was busy inventing it completely on their own. Archaeologists like Alfonso Caso and his colleagues Stirling and Ekholm proved that rotational movement wasn't just understood in Mesoamerica, it was mastered. Spindle whorls, drills, cylindrical stamps, and yes... wheeled figurines with wooden axles. The only two regions on Earth to officially independently invent the wheel? Mesopotamia and Mesoamerica.
