The sophisticated 7,000-year-old structures found near Leipzig, Germany, were built by farmers before Europe had metal tools, archaeologists say.
The people who lived in eastern Germany around 7,000 years ago are thought to have been some of the first farmers. Now, new archaeological evidence suggests they were also surprisingly skilled woodworkers, crafting intricate water wells some two thousand years before metal tools were forged in Europe.
Sophisticated in construction, four wells discovered near Leipzig were built using stone carving implements and wooden mauls and wedges, said Willy Tegel, a researcher at the Institute for Forest Growth at the University of Freiburg in Germany.
"The first farmers were also the first carpenters," Tegel and his colleagues wrote in a study published this week in the journal PLoS One.
