Popular Science News | Facebook – 5000BC version

It seems that cavemen invented a version of Facebook thousands of years ago. Two granite rocks,  each the size of a football pitch, have been to found to contain thousands of pictures representing the collected knowledge of several clans. Scientists believe that members of the clans regularly returned to the same place to add survival tips. These actions helped social bonding and disseminated ideas between clans.

Analysis of the time-line of these drawings show a gradual development of ideas and a spread of these images from rocks onto tools, for example. At some point in time putting images on the rocks stopped, possibly because the tribesmen objected to changes to the way it was used, just like with the modern Facebook.
