This is an example of a simulation
It is based on a unix program that was probably the first Internet-ready
anthropology simulation published on CSAC's Social Anthropology Bulletin Board
in 1986... based on R. Lee's paper (1969),
!Kung Bushman subsistence. An input-output analysis
The panel to the top-left shows locations of bands and waterholes. The panel to
the top-right shows the density of nuts and the status of waterholes. The
bottom panel reports the demographic structure of the bands, how much labour
was expended and the composition of their diet that week. S is an index that
Lee computes to indicate satisfaction, based on diet and labour input.
