It has long been speculated that a comet strike caused a sudden drop in the Earth’s temperature during a period called the Younger Dryas. Now, researchers at the University of Edinburgh have found support for this view. They matched carvings at the Gobekli Tepe temple site in Turkey to star asterisms, and found that the famous “Vulture Stone”, dated 10,950±250 BC, fits well with the Younger Dryas event estimated at 10,890 BC. The date of the strike coincides with the emergence of agriculture and the beginnings of modern civilisation.
