Aristotle proclaimed that human beings are inherently social living creatures. Since his time, the development of Biology and Sociology have become areas of study. Social Biophilia is a series that connects Biophilia Hypothesis Theory with key Sociology principles to examine this phenomenon of human beings' desire for connection with their environment and to other living creatures. The series examines and uses U.S. Route 66 as the key subject in exploring these topics to provide evidence of connectivity, either present or documentation of once-existing connections. Architecture, Landscape, and Man-Made structures all provide evidence of an individual's need to connect.
