The similarities in their tool-making technique point to an ancient, far-reaching communication network. The fascinating fact here is that ancient Africans used this meticulously designed tool, over distances that were not easy to traverse. This shows that 65,000 years ago people in South Africa were in the process of creating a common and cooperative culture, extending over a greater distance than usual, which resulted in an ancient communication network. It was around this time that the first modern humans began to migrate from Africa to Eurasia in large numbers. The researchers involved in this new study believe that the apparent interdependence in their tool-sharing practices helps explain how this large-scale exodus was possible and successful.
