Broad Spectrum Revolution Dec 16th 2011, 11:01 The Broad Spectrum Revolution (sometimes abbreviated BSR) refers to a proposed subsistence shift at the end of the last Ice Age (ca 12,000-8,000 years ago). People who had been primarily hunters of large-bodied terrestrial mammals broadened their dietary bases to include small animals and plants, becoming hunter-gatherers. Broad Spectrum Revolution and Population Growth The broader resource base, so the theory goes, led to increased population density in some places, and that in turn led to social complexity: the Neolithic Revolution. The BSR was proposed by Kent Flannery in 1969, building on work by Lewis Binford. The major change in the theory today is that it appears that the broadening of resource base began earlier, during the Upper Paleolithic, evidenced by use of grains and small birds at sites such as Ohalo II in Israel and Xiaojingshan in China.
