Bernal states that the bullock-cart combined two critically important ideas—the use of animal power and the wheel. "These inventions were to have enormous material and scientific consequences. The cart and the plough between them enabled agriculture to be spread over all open plains and so far beyond the limits of the old civilizations. The increased possibilities and speed of transport by cart and even more by ship, together with the need to know the sources of valuable materials, led to deliberate exploration and to the beginnings of geography."³
