Wheel
Amanda Gonsteina
The funny thing about wheels is that we are used to seeing them in use all around us but they are a manmade thing. There aren’t any wheels in nature and the only ones in the animal world that create and use them are human beings. Before the invention of the wheel people had to pull or push things along the ground.
And Thats How The Wheel Was Invented
The wheel is another invention so ancient that we have no way of knowing who first developed it.
Wheels are generally circular in shape, and rotate, primarily on an axis, and are said to be one of the most important inventions of all time.
The oldest wheel and axle mechanism we've found was near Ljubljana, Slovenia, and dates to roughly 3100 B.C. which is the early Bronze Age. Before that, they used inclined planes and levers to move anything around.
Wheels are often used in transportation, farming and industry machines, as well as on moving toys.
