Archaeologists have unearthed at Leipzig's oldest well in Europe. People dug it more than 7,000 years ago, reinforcing walls, oak beams, to provide themselves with water. Finding suggests that people long before the invention of the first metal tools could create complex wooden structures, media reported.
The first builders, is also likely to have been the first and carpenters in Europe, said archaeologist from Freiburg Willy Tegel in the journal Plos One. According to the researchers, the well is the world's oldest surviving wooden structure. This suggests that the society at that time was at a higher level of development than previously thought.
At the beginning of the Neolithic people dug a pit to a depth of seven meters and besieged her tree. They split the logs and then put together closely angled connection, making mine shaft. "This sophisticated technology has been a big surprise," — wrote Tegel.
Four wells Neolithic period were built from 6000 to 4000 BC. e., when, according to experts, there have been fundamental changes in human history. At that time people began to abandon the life of hunter-gatherers and gradually began to shift to a sedentary lifestyle. To create permanent settlements and agriculture were required fundamental technical innovation.
But the wooden house at the time did not survive. Thus, experts can only imagine how life appeared early farmers. Therefore, the discovery of four wooden wells is important, said Tegel.
Just because the wooden boards were below the water table and have been deprived of oxygen, they survived the millennia. Based on the growth rings in the wood of the scientists were able to determine the year when the trees were cut down, from 5206 to 5098 BC. e.
Finally, the scientific view that there were still about our ancestors, should be reconsidered, said Tegel. "All the reconstructed buildings of this period and the infrastructure is likely to have been underestimated. If people were able to carry out such a complex wood processing, it is necessary to revise the reconstruction of buildings, "- said the archaeologist.
