Despite notable differences in appearance and governance, ancient human settlements functioned in much the same way as modern cities, according to new findings by researchers at the Santa Fe Institute and the University of Colorado Boulder.
Previous research has shown that as modern cities grow in population, so do their efficiencies and productivity. A city's population outpaces its development of urban infrastructure, for example, and its production of goods and services outpaces its population. What's more, these patterns exhibit a surprising degree of mathematical regularity and predictability, a phenomenon called "urban scaling."
But has this always been the case?
