Science around 5,000 BC

The Globe

Even academics as revered as Lord Colin Renfrew, Disney Professor of Archaeology at the University of Cambridge, have concluded that every group of humans in the world once spoke the same language – and that the date of this convergence was as recent as 15,000 years ago. We have taken a similar approach to that used for tracing the origin of language, but using measurements, astronomical methodologies and geometry instead of words, and these indicate a convergence something over 5,000 years ago.

Dechend and her associates have found evidence of an awareness of the Precession, the changing zodiacal position of the rising sun at the spring equinox, in some of the oldest fragments of art and myth of both ancient and primitive cultures. In the opinion of these investigators, the recognition of the Precession of the Equinoxes first occurred in the Near East at approximately 5000 BC and subsequently spread throughout the archaic world and into the recesses of primitive and ancient mythology.

In the southwest [Iran] the early fifth millennium saw further increases in the number of new agricultural sites in Susiana, while in the northeast a chain of perhaps twenty settlements now stretched along the foothills of the Kopet Dagh and into the Gurgan plain. On the plateau, copper was already being cast into molds at Tepe Gabristan, where a recently discovered workshop for coppersmiths, complete with crucible, kiln, and molds, has been dated to the early fifth millennium BC. The end of the fifth millennium would see the first recorded use of the potter's wheel at Sialk, an innovation which, like the advances in metallurgy, was then to spread westward from Iran into southern Mesopotamia , and not, as was once supposed, the other way around.

By about 4500 BC--1500 years and more before the Egyptians began to build large stone buildings--farmers in Spain were using large stones weighing many tons to build tombs, and over the next several millennia people all over Western Europe built large monolithic tombs. (Patterns in Prehistory)
