The wheel The wonder of the wheel When the first humans decided to leave their homes over 100,000 years ago in search of new places to live and better sources of food, they did it on foot. Humans continued walking across the globe for the next 94,000 years, until about 6,000 years ago when a number of important changes took place. For instance, in the Central Asian country of Kazakhstan, people started to ride horses. Although this meant that people could travel further and faster, transporting large amounts of goods was still a difficult job. That all changed, however, a few hundred years later with the invention of the wheel. Who first invented the wheel We will never know for sure, but the inventors probably first used wheels to make pottery. Later, they realized that they could also use them to transport people and things. They soon attached wheels to horse-pulled vehicles. Farmers were suddenly able to transport their goods to markets far away. This invention increased national and international trade. The wheel changed the way villages, towns and even countries did business with each other, but it wasn’t perfect. The roads were old walking paths. These old paths quickly became extremely difficult to use in wet weather. As a result, the first roads made of stone appeared after the arrival of the wheel. The Romans then invented new road-building techniques. The new roads were very good, and we still use some of them today. The wheel not only changed the way humans move, but it also allowed us to build all types of amazing machines. Windmills, clocks and other machines all use wheels, and the Industrial Revolution depended on the wheel. Even in our digitalized world, we still use wheels in devices such as 3D printers. Without doubt, the wheel is one of the most important inventions of all time. Look at the title and the pictures. Then answer questions 1 & 2. 1. What is the article mainly about 2.
