The History and Development of the Wheel: From Pottery to Transportation
TLDR The wheel was not invented until the Bronze Age and was initially used for pottery-making. The development of the wheel for transportation required the invention of the axle, and while it spread across Asia, Europe, and Africa, it was never used in the Americas due to the absence of draft animals and the type of agriculture practiced.
Timestamped Summary
00:00
The wheel was not the first invention, and there were likely other inventions that had to come before it.
02:02
The wheel was not invented until the Bronze Age, after the development of megalithic structures, agriculture, irrigation, and bronze metalworking.
03:46
The first wheels were not used for transportation, but rather for pottery, as a technical innovation to improve the quality and efficiency of pottery-making.
05:22
The development of the wheel for transportation required the invention of the axle, which had to be a perfect fit with the wheel and have smooth ends to reduce friction.
06:54
The wheel and axle were likely invented once and spread across Asia, Europe, and Africa, with innovations such as spokes and iron rims being made over time, but the wheel was never used in the Americas despite their advanced engineering capabilities and evidence of roads.
08:33
The lack of draft animals in the Americas and certain parts of Africa likely contributed to the absence of wheeled vehicles in those regions, despite evidence of the concept of the wheel being understood through children's toys and trade and cultural communication amongst tribes and civilizations.
10:10
The absence of draft animals in certain regions, such as the Americas and parts of Africa, meant that the type of agriculture practiced did not require plows, which in turn meant that the necessity for the wheel and axle was not present.
