Decisive challenges of the Neolithic way of life were increasing size and densities of social communities. Excavations at the Late Pre-Pottery Neolithic site of Ba`ja, in the Greater Petra Area, since 1997 make this site an excellent archive for studying these social processes. New investigations within the framework of the Ba`ja “Household and Death” Project revealed unexpected evidence for increasing social differentiation and indicate close relationships of living and dead, creating strong but also demanding collective memories.
