Excavations at a 6,000-year-old archeological mound in northeastern Syria called Tell Brak are providing an alternative explanation for how the first cities may have grown. Archeologists have thought cities generally began in a single small area and grew outward — but evidence indicates that the urban area at Tell Brak was a ring of small villages that grew inward to become a city. The finds, reported Friday in the journal Science, provide insight into political development in the region. ‘Urbanism does not appear to have originated with a single, powerful ruler or political entity,’ said archeologist Jason Ur of Harvard University, who led the research. ‘Instead, it was the organic outgrowth of many groups coming together.’ The city, whose name is unknown, was in the ancient empire of Mesopotamia, which encompassed what is now southern Iraq and northern Syria.
