The Invention and Spread of the Wheel: A Key Development in Human History
TLDR The wheel was invented in the Bronze Age and came after the development of megalithic structures, agriculture, irrigation, and bronze metalworking. It spread throughout Europe, Asia, and Northern and Eastern Africa, but was never used in the Americas due to a lack of draft animals and specific agricultural practices.
Timestamped Summary
00:00
The wheel was not the first invention and there were many things that had to be invented before the wheel could be discovered.
01:33
The wheel was invented in the Bronze Age and came after the development of megalithic structures, agriculture, irrigation, and bronze metalworking, and the first wheels were used for pottery.
03:00
The first evidence of wheels for transportation comes from the North Caucasus, Eastern Europe, or Central Asia, but it is not clear if the wheel actually originated from Mesopotamia.
04:20
The development of the wheel for transportation required the invention of the axle, and the current belief is that the wheel and axle were likely invented once and then spread to different regions.
05:40
The wheel and axle technology spread throughout Europe, Asia, and Northern and Eastern Africa, but was never used in the Americas, despite their advanced civilizations and engineering capabilities.
07:06
The reason why wheels weren't used in the Americas is likely due to a lack of draft animals, while in Africa, wheeled vehicles were common in the northern parts but not in the south.
08:33
The lack of draft animals and the specific agricultural practices in Southern Africa and the Americas, as well as the primary use of llamas as pack animals in the Andes Mountains, contributed to the delayed adoption of the wheel in these regions.
