STORRS, CONNECTICUT—By analyzing nearly 3,000 stone artifacts excavated at the site of Nor Geghi in Armenia, Paleolithic archaeologists have concluded that ancient stone toolmaking technology may have been invented independently in places other than Africa, where it was thought to have originated. Rather than spreading from a single point of origin as has been thought, toolmakers may have been creating similar tools as much as 325,000 to 335,000 years ago in several parts of the world, including Eurasia and Africa. "Technological innovation was something that our ancestors were very good at," study leader Daniel Adler told livescience.
