In brief, Göbekli Tepe is a relatively newly discovered temple complex, considered the oldest megalithic place of worship known. It located in Anatolia, and is dated to 11,000 BC.
Schmidt has uncovered a vast and beautiful temple complex, a structure so ancient that it may be the very first thing human beings ever built. The site isn't just old, it redefines old: the temple was built 11,500 years ago—a staggering 7,000 years before the Great Pyramid, and more than 6,000 years before Stonehenge first took shape.
"The people here invented agriculture. They were the inventors of cultivated plants, of domestic architecture," [Schmidt] says.

Göbekli Tepe is regarded as an archaeological discovery of the greatest importance, since it profoundly changes our understanding of a crucial stage in the development of human societies. Apparently, the erection of monumental complexes was within the capacities of hunter-gatherers and not only of sedentary farming communities as had been previously assumed. In other words, as excavator Klaus Schmidt put it: "First came the temple, then the city." This revolutionary hypothesis will have to be supported or modified by future research.

Predating Stonehenge by 6,000 years, Turkey's stunning Gobekli Tepe upends the conventional view of the rise of civilization

Six miles from Urfa, an ancient city in southeastern Turkey, Klaus Schmidt has made one of the most startling archaeological discoveries of our time: massive carved stones about 11,000 years old, crafted and arranged by prehistoric people who had not yet developed metal tools or even pottery. The megaliths predate Stonehenge by some 6,000 years. The place is called Gobekli Tepe...
Questions and discussion points include:

  • What was/were the Y-DNA haplogroups of the builders of Göbekli Tepe?
  • What are the geographic origins of the builders? Did they travel south from the Black Sea area, or north from Mesopotamia?
  • How about their phenotypes? Crogmagnid? Archaic homo sapiens? More progressive?
  • Göbekli Tepe is only approximately 300 miles from the site of Hattusa, the earliest Indo-European city, also in Anatolia. Could Anatolia therefore have more of a role as the "cradle of civilization" than previously thought?

I look forward to your thoughts!
