Revolutionary Ideas from Göbekli Tepe

(via Wikipedia)

National Geographic has an article (HT Vipul) on Göbekli Tepe in Southern Turkey where people constructed a huge temple complex much before the invention of agriculture. This site is now prompting historians to rethink the theories on the origins of complex societies. How were foragers, who usually follow the resources like the Nanook, able to stay at one place and move 16 ton stones without wheels or animals? Why did they even bother constructing such a massive structure? Did pilgrimage pre-date the Neolithic revolution?

Discovering that hunter-gatherers had constructed Göbekli Tepe was like finding that someone had built a 747 in a basement with an X-Acto knife. “I, my colleagues, we all thought, What? How?” Schmidt said. Paradoxically, Göbekli Tepe appeared to be both a harbinger of the civilized world that was to come and the last, greatest emblem of a nomadic past that was already disappearing. The accomplishment was astonishing, but it was hard to understand how it had been done or what it meant. “In 10 or 15 years,” Schmidt predicts, “Göbekli Tepe will be more famous than Stonehenge. And for good reason.”[Göbekli Tepe]

There is a new explanation for the origin of agriculture

If these archaeologists were correct, these protovillages provided a new explanation of how complex society began. Childe thought that agriculture came first, that it was the innovation that allowed humans to seize the opportunity of a rich new environment to extend their dominion over the natural world. The Natufian sites in the Levant suggested instead that settlement came first and that farming arose later, as a product of crisis. Confronted with a drying, cooling environment and growing populations, humans in the remaining fecund areas thought, as Bar-Yosef puts it, “If we move, these other folks will exploit our resources. The best way for us to survive is to settle down and exploit our own area.” Agriculture followed.[Göbekli Tepe]

and it is connected to religion

Schmidt speculates that foragers living within a hundred-mile radius of Göbekli Tepe created the temple as a holy place to gather and meet, perhaps bringing gifts and tributes to its priests and crafts­people. Some kind of social organization would have been necessary not only to build it but also to deal with the crowds it attracted. One imagines chanting and drumming, the animals on the great pillars seeming to move in flickering torchlight. Surely there were feasts; Schmidt has uncovered stone basins that could have been used for beer. The temple was a spiritual locus, but it may also have been the Neolithic version of Disneyland.

Over time, Schmidt believes, the need to acquire sufficient food for those who worked and gathered for ceremonies at Göbekli Tepe may have led to the intensive cultivation of wild cereals and the creation of some of the first domestic strains. Indeed, scientists now believe that one center of agriculture arose in southern Turkey—well within trekking distance of Göbekli Tepe—at exactly the time the temple was at its height. Today the closest known wild ancestors of modern einkorn wheat are found on the slopes of Karaca Dağ, a mountain just 60 miles northeast of Göbekli Tepe. In other words, the turn to agriculture celebrated by V. Gordon Childe may have been the result of a need that runs deep in the human psyche, a hunger that still moves people today to travel the globe in search of awe-inspiring sights.[Göbekli Tepe]

The First Buildings

We know that agriculture was invented about 12,000 years back in various places around the world, starting with the Fertile Cresent. Many models have been proposed to explain why humans left a foraging for farming. With the discovery of the 11,500 year old temple at Göbekli Tepe in Turkey, we also know that religion played an important role quite early in the settled life.

Now we have new evidence of how people lived during that transitory period. The earliest permanent buildings found during this period were not individual homes, but places for communal living or gathering.

Finlayson, Mithen, and their colleagues conclude that the evidence from WF16, combined with evidence from other sites, suggests that the earliest villages were not made up of houses, but rather communal structures where people came together to process their wild harvests and possibly also to engage in community performances. “These settlements appear to be all about community and not about emerging households,” the team writes, adding that this “ritualized community activity” might have helped to bring together the work force necessary to harvest the wild crops.

The authors don’t speculate on where the farmers lived, and there is no way to be sure. Researchers working at similar sites have surmised that they lived in small camps near the central site, but such open air habitations are very difficult to find and often leave little or no archaeological traces.

Archaeologist Trevor Watkins, emeritus at the University of Edinburgh in the United Kingdom, says he “agrees strongly” with the authors’ conclusion that the social changes that took place during the transition from hunting and gathering to farming were at least as important as the later economic changes that led to full-blown domestication of plants and animals. But he thinks that it’s still possible that some of the other buildings at WF16 were used as domestic dwellings. Nevertheless, Watkins says, the communal activities at WF16 and other Neolithic sites probably created “powerful bonds of collective identity” in the earliest farmers that kept them together in stable societies “over many generations.”[First Buildings May Have Been Community Centers]

Who caused the Climate change?

It is fashionable to remark that while early humans lived in harmony with nature, the modern man abuses it. Many believe that it is massive use of fossil fuels in the post-Industrialization era that triggered global climate change. But a new model says that climate change was triggered by the burning of forests for agriculture. Though the population was smaller, farming techniques were not optimized resulting in more land use per person for food production.

He said that early populations likely used a land-clearing method that involved burning forests, then planting crop seed among the dead stumps in the enriched soil. They would use a large plot until the yield began to decline, and then would burn off another area of forest for planting.

They would continue this form of rotation farming, ever expanding the cleared areas as their populations grew. They possibly cleared five or more times more land than they actually farmed at any given time. It was only as populations grew much larger, and less land was available for farming or for laying fallow, that societies adopted more intensive farming techniques and slowly gained more food yield from less land[Agricultural Methods Of Early Civilizations May Have Altered Global Climate]

But if you put the blame entirely on the early farmer, that would be wrong. New studies show that even the hunter-gatherer managed to affect their environment, through the use of fire, translocation of animals and altering the marine ecosystem.

Rick has also found layers of sea otter bones thousands of years old in California’s Channel Islands. The layers above just had sea urchin remains. He thinks people killed the otters because they ate too many shellfish. Since otters also prey on sea urchins, the urchin population exploded. All those urchins ate up the kelp forests, creating what Rick calls an “urchin barren.” [For Early Man, It Wasn’t Easier Being Green : NPR]

But the key to remember is that, the ancient man had no choice and most of the damage was unintentional. Also there was no one to tell them the Inconvenient Truth.

“The take-home point to some extent is that humans do things to make their life easier,” Hames says. “It was really hard to make a living back then, so you know, you took advantage of the knowledge and skills you had in order to make the environment useful to you.” [For Early Man, It Wasn’t Easier Being Green : NPR]
