Resumen de Early civilization in the Casma Valley, Peru

Shelia Pozorski, Thomas Pozorski

• Since 1980 intensive archaeological investigations have been carried out at several early sites, occupied from late preceramic through early ceramic times (4150–2950b.p.), in the Casma Valley, Peru. Preliminary results document increasing societal complexity over time as reflected in the exponential growth of monumental architecture, the acquisition of irrigation agriculture, the rise of two complex polities within the valley and the separation of religious and secular power within the ruling élite.
