Exposición TecnoRevolución: la era de las tecnologías convergentes.
Espacio telefónica, del 31 de enero al 11 de mayo del 2014.
More than three million years ago, when human beings had not yet appeared and elaborated tools did not exist, prehominids used objects encountered in their surroundings to meet some of their needs. It was a purely animal technique, lacking a capacity for innovation and tied to genes.
During the pre-technological age, the tools used were simple stones or teeth which on account of their shape, were appropriate for cutting, tearing o defending oneself. In the history of life on Earth, this period lasted more than 3400 million years.
