Both elements helped the human communication, and with it they developed the commerce and the exchange of goods.

Explanation:

The wheel is a mechanical part that rotates around an axis. It can be considered a simple machine, and is part of the set called machine elements. It is one of the fundamental inventions in the History of the humanity, for its great utility in the elaboration of pottery, and also in the terrestrial transport, like fundamental component of machines. The knowledge of its origin is lost in time, because no one knows who invented it and its multiple uses have been essential in the development of human progress: Sumerians, Chinese, etc. At present, semiologists and linguists consider that writing is completely after speech, although some semiologists at the end of the 20th century came to suppose that the scriptures are prior to articulated verbal language since there is a pleasure (to use a Barthesian term) on the part of the human subject in leaving traces of himself in various supports (handprints, notches, stripes, representations more or less figurative as is observed in the Magdalenian), but such proto-scriptures do not seem to be indications that the written texts were anticipated to the speech; in any case, with the writing as "second memory" the speech was reinforced by the writings; moreover, the writing allows for an additional reflection, and this means that the written language can have a clear strategy that the oral language of the writer lacks.
