This was a serious problem when you were transporting something very heavy. Too many times, one of the runners slipped off the edge of the roller and the whole load tipped over. But the once again Sumerians would not give up. There had to be a better answer. They noticed that after a roller had been used for a while, it started to get grooves where the runners rubbed against the wooden roller.
They came up with a terrific idea: Why not actually cut grooves where you want the runners to ride on the roller? This would keep them in place. The Sumerians quickly cut grooves into all their rollers and ended up with a much more efficient wheel.
Still, to move loads this way was tiring and required lots of people. Just moving the rollers to where they had to be used was an exhausting chore. The Sumerians reasoned that it might not be necessary to use the whole heavy roller. Only the ends were actually needed to prop up the load. What would happen if they cut out some of the excess wood in the middle of the roller and just left the two ends connected by a narrower middle piece?
To keep the sledge in place, the Sumerians attached four pegs two on each side of the sledge. What a difference! The Sumerians now had a lighter-weight cart to carry their loads. They tinkered with their new invention and decided to get rid of the pegs. They added a piece of wood to each side of the cart. These pieces hung down under the cart. They then drilled holes in these pieces so that the axle could easily roll inside them. Now the sledge was permanently attached to the axle and the wheels.
What the Sumerians ended up with was a two-wheeled cart. This was later developed into a chariot that could be pulled by a horse or donkey.
Other surrounding civilizations copied the design and quickly adapted the wheel to the needs of their own cultures. Who would ever think that a device meant for making pottery would be the inspiration for one of the greatest and most wide-reaching inventions of mankind?
Think about how many ways wheels are used today—not just for transportation, but for manufacturing, home appliances and recreation. We are in debt to the Sumerians for their ingenuity and persistence. After a long time, around BC, an idea struck one of the wise Homo sapiens residing in Mesopotamia present-day Iraq. He cut a disc from the trunk of a tree and made a hole in its center; the end product was the wheel —arguably the greatest invention in human history! THE WHEEL is often described as the most important invention of all time — it had a fundamental impact on transport and later on agriculture and industry.
Soon, it became common for the wheels to turn around a fixed axle. Wheels with spokes, first made around BC, were lighter, enabling vehicles to move faster.
The Chariot Scale model of a simple two-wheeled chariot which was invented by the Sumerians in Mesopotamia. The Sumerians didn't invent wheeled vehicles, but they probably developed the first two-wheeled chariot in which a driver drove a team of animals, writes Richard W. Wheels first appeared in ancient Mesopotamia , modern-day Iraq, more than 5, years ago.
They were originally used by potters to help shape clay. Later, wheels were fitted to carts, which made moving objects around much easier. Turning the axle turned the entire wheel , saving both time and energy. What was the first invention?

Biomimetic clothing 10, BCE Earliest boats are constructed. Ships and boats. Who invented homework? Roberto Nevilis. The stone wheel originated in China and Turkey. An axle is a small rod that helps the wheel to turn more easily.
Early axles were made of wood, which was threaded through a small square or circular hole made in the center of the wheel. These were thinner wooden pieces or metal bars that ran across the wooden planks to hold them together. Wheels could be made lighter by cutting out sections of wood. Yet as ingenious as this inventor was, their toy did not spark a societal revolution. The wagon, it seems, was irresistibly useful.
They would have been loud; they would have been slow. And they were powered by teams of oxen, which were by themselves some of the largest animals in the steppe. The invention of the wagon was the prehistoric equivalent of Sputnik; it did not go unnoticed. Because the two oldest wheels archaeologists have found vary significantly in design—one has an axle fixed to the wheel as it does on a modern train, the other spins freely on the axle like on a modern car—Anthony suggests that at least some wagon builders copied what they saw from afar without being able to inspect it closely.
The invention and widespread adoption of the wagon had an immediate and dramatic effect on societies throughout the Middle East and Europe. Populations that were previously clustered around rivers exploded onto the productive but unexploited steppe.
The wagon changed entire economies, lifestyles, wars, and even languages. And scaling a miniature wheel required its own genius. Wagons and references to them explode in the archaeological record from the Middle East to Western Europe within a few generations of each other.
One comes from a Slovenian bog in Ljubljana; the second comes from the remarkable Yamnayan culture grave just east of the Black Sea in the North Caucasus, Russia, where archaeologists found not only a wheel but an entire wagon complete with the skeleton of a thirtysomething man sitting atop it.
Archaeology is not the proper science for pinpointing the location of viral inventions. There are, however, linguistic reasons to suspect the Yamnayan man buried with his wagon may have lived close to where the invention occurred. When the Spanish brought the tobacco plant back from the Caribbean, for example, they kept the local Taino word tabako.
