Wagons are believed to have been first created in western Asia around 3500 BC. Initially, because the wheels were disc-shaped, they were pulled by cattle due to their heaviness. However, after the invention of spoke wheels, horses could pull the wagons because they were lighter. Naturally, there was a big difference between the speed of a wagon pulled by cattle and one pulled by a horse. This led to a decrease in travel time. A minor adjustment to the spoke design sparked a significant change in human civilization. Nearly all innovations start small, but even the tiniest change can have enormous consequences. Many unseen factors contribute to this innovation in our lives. - Joseph’s “just my thoughts”
