The wheel is the(simple) yet perhaps the most remarkable of all(invention) because there are no wheels in nature., then, did man come to invent the wheel? Perhaps some early hunters found that the body of heavy animal could be rolled through the forest on logs (圆木) more(easy) than they could carry it. However, the logsthem) weigh a lot.
It must have taken a great prehistoric thinker to imagine two thin slices of log connected, at their centers by a string stick. This would roll along just the logs did, yet be much lighter and easier(handle). Thus the wheel and axle came into being and with them the first carts.
