If the history of our species to date was represented as a single day, then civilisation would have begun in the final half-hour. At least, that’s assuming Homo sapiens emerged around 300,000 years ago and civilisation began 6000 years ago with the first cities in Mesopotamia. In this tale, civilisation represents a seismic cultural shift that traces its roots back to the start of farming, some 5000 years earlier, and flows inexorably through settlement, population expansion and social stratification to urbanisation.
These days, we tell a different story. For a start, we no longer see Mesopotamia as ground zero for urbanisation: cities were springing up in other places, including India, China, Egypt and central Europe, at around the same time. What’s more, agriculture wasn’t the catalyst for civilisation we once thought. Instead, it appears to have been an invention born of necessity when the traditional hunter-gathering life became untenable – and there are plenty of examples of groups reverting when farming didn’t work out. This means we must redraw the timeline that saw our ancestors shift away from the lifestyle that had worked well for most of human history. It also requires us to question the very definition of civilisation.
An obvious place to start looking for answers is Göbekli Tepe in southern Turkey. Archaeologists digging there since 1995 have unearthed a series of circular enclosures containing huge, T-shaped stone pillars. Dating back almost 12,000 years, these are the oldest known megalithic monuments. Building them would have required cooperation between many workers, along with leaders to coordinate and…
