Thousands of tools from the Paleolithic era have been discovered from a site in Armenia.
The latest discovery gives scientists a better insight into how
technological developments evolved and spread in the world. The research
teams which included scientists from across the world and a team from
Royal Holloway, University of London believe that they have unearthed
evidence that the ancient technique of Levallois which is used for
making hunting weapons was actually invented in Africa and later spread
across the world. Details of the study were published in the journal
Science.
