ABSTRACT
The capacity for curiosity in human beings is a defining characteristic of our species, essential to all forms of creativity and innovation, and especially the desire for information. Additionally, we are naturally mobile creatures, biologically evolved and motivated to move and range in the physical environment. These qualities have made human beings incredibly adaptive, able to transfer knowledge and information from place to place, and have allowed human societies to flourish in many different situations. Studies in human communication and evolutionary biology argue that there is a powerful connection between the human capacity for communication and the development of human societies. Lasswell (1949) proposed that the communication process performs three functions
a Surveillance of the environment, disclosing threats and opportunities affecting the value position of the community and of the component parts within it;
b Correlation of the components of society in making a response to the environment;
c Transmission of the social inheritance.
