Tourism could be defined as a form of curiosity, perhaps to be placed in an evolutionary framework?
Example:
Evolutionary biologists might hypothesize that brain and neural organization has been naturally or sexually selected to proximately 'force' or drive organisms to be physically mobile principally to be trained to be in good physical condition. In this framework, curiosity might provoke training and therefore increase physical performance. Perhaps curiosity resulting from brain structure organization has been evolutionary selected to provoke training aimed to improve physical (and so-called ‘intellectual’) performance. Perhaps tourism as a form of curiosity forcing individuals to move to physically and mentally train might be defined as an artifact or by-product of evolutionary human history?
