Passage Two
Man‘s first real invention， and one of the most important inventions in history， was the wheel. All transportation and every machine in the world depend on it. The wheel is the simplest yet perhaps the most remarkable of all inventions， because there are no wheels in nature—no living thing was ever created with wheels. How， then， did man come to invent the wheel? Perhaps some early hunters found that they could roll the carcass of a heavy animal through the forest on logs more easily than they could carry it. However， the logs themselves weighed a lot.
