We cannot imagine our lives without movement. Movement was made possible when humans invented the wheel. It happened several thousand years ago. First wheels were used in pottery and then wheeled vehicles appeared. Early wheels were simple wooden disks with a hole for the axle. Some of the earliest wheels were made from horizontal slices of tree trunks. Then people invented the spoked wheel which allowed the construction of lighter and swifter vehicles. That was the time when people started travelling and discovering new lands.
Nowadays wheels are so common in technology that it is practically impossible to live without them.
