A recent article in The New Yorker got me thinking about the Neolithic Revolution. The article was about an archeological dig in southeastern Turkey known as Gobekli Tepe (“Fat Hill” in Turkish). The site contains more than 60 multi-ton limestone pillars. It’s estimated it would require at least 500 men working in a directed, organized way to quarry, move, and erect these pillars. The pillars are engraved with high and low reliefs of predatory animals. Because, unlike the cave paintings of the Upper Paleolithic, the reliefs offer no portrayal of daily life, they are thought to be symbolic, or perhaps guardians. The pillars themselves are T-shaped and give evidence of representing stylized human beings. Gobekli Tepe was designed and built by hunter-gatherers as a centralized meeting place, a sanctuary if you like, for people from a 100-mile radius. You could think of it as party-central, a Stone Age Studio 54, a place where unknown ceremonies were performed along with great feasts, perhaps including fermented beverages and/or psychotropic plants. The oldest sections of Gobekli Tepe were built around 12,000 years ago (as compared to 4500 years ago for Stonehenge), and thus predate by millennia the conditions which were thought to be prerequisite for monumental architecture to occur. Gobekli Tepe turns previous thinking about the Neolithic Revolution on its head.
Hominids have been on earth for approximately 2.6 million years. Our particular species has been around for about 200,000. 95% of that time we made our living as foragers. Women scoured the countryside for nuts, berries, roots, fruits, wild grains, anything edible. Men hunted for meat. And they were pretty successful. Studies have shown that in most cases our nomadic hunter-gatherer ancestors were able to support themselves on an investment of only about 20 hours a week. Nevertheless, over a 3-thousand-year period, independently in several different locations, they transformed themselves into sedentary farmers. This event, the domestication of plants and animals (i.e., sheep, goats, cattle—dogs were domesticated much earlier, at least 33,000 years ago), marks the transition from the Paleolithic to the Neolithic era and is known as the Neolithic Revolution. Gobekli Tepe, it now appears, is where this transformation began. DNA analysis of modern wheat shows that it is genetically most closely related to the wild wheat found near this site.
Contrary to what you might assume, this change did not result in an improved standard of living. The physical record shows that subsequently people were more anemic, had worse teeth, more spinal deformities, more infectious diseases, worked harder and died younger. They actually shrank in size, from an average 5’10” for men and 5’6” for women during the Paleolithic to an average 5’6” for men and 5’1” for women. Socially, they went from egalitarianism to a hierarchical structure with a ruling class. Some say that the legends of a past Golden Age, a Garden of Eden, represent racial memories of the old hunter-gatherer days. Our ancestors had it pretty good as hunter-gatherers and could have gone on indefinitely that way. Instead, they took the path that led to where we are now. So why did they make the fateful change?
There have been a number of theories. To me, the one that makes the most sense is that they were victims of their own success. Population growth led to increasing conflicts between competing groups, forcing the groups into more confined territories, which then had to be more thoroughly exploited. One can imagine some wild wheat being accidentally left behind, and when the group returned the next season it found a new crop, so it got the notion to enlarge on the practice. Then, agriculture produced a surplus, and the surplus needed to be stored for future use. A surplus allows for further growth in population. Jared Diamond, in Guns, Germs, and Steel, says that the hunter-gatherers were seduced by the temporary abundance produced by agriculture, but then population caught up and they found themselves trapped in a vicious cycle of increasing production and increasing population, the cycle we are still caught in today.
It has long been the assumption that agriculture came first. The agricultural surplus required storage and that plus the presence of domesticated animals led people to stay in one place and build permanent structures. In particular, monumental architecture required the organization and division of labor and thus it is only after the Neolithic Revolution that monumental architecture appears.
Gobekli Tepe tells a different story. It shows that the temple preceded the city. It suggests that, instead of agriculture creating the need to stay in one place, the need for division of labor, social hierarchies, and complex symbol systems, rather it was the desire to come together in one place to celebrate their existence that required all these things. Perhaps the need to protect wild grain from marauding herds of gazelles and donkeys fired cooperation among the local human groups, and this required social organization and a means of cementing and celebrating that cooperation. It may be that the Neolithic Revolution was not so much a choice as something bumbled into. Our ancestors were trying to make their lives even easier and in the process made them a lot more complicated.
Only 5% of Gobekli Tepe has been excavated, so it’s possible that more discoveries there will enhance our insight into this crucial transition in the developmental history of our species.
