Initially thought to only be between three million and 12,000 years old, new datingread more
Archaeologists working in Turkey have uncovered a sister site to the ancient ceremonial complex at Göbekli Tepe—a somewhat smaller group of otherwise similar structures that may be even older than its more famous counterpart. And the two ancient sites are not alone: researchers have identified no less than 12 sitesread more
