Broad spectrum diet
The search for more food within these marginal habitats forced foragers to diversify the types of food sources harvested, broadening the subsistence base outward to include more fish, small game, water fowl, invertebrates likes snails and shellfish, as well as previously ignored or marginal plant sources.

The growth and reproduction of certain plants and animals became vastly popular. In terms of plants, it would be expected that foodstuffs that had once been ignored because of difficulty of extraction were now included in a diet. Because large animals became quite scarce, people had to find new resources of food and tools elsewhere. Please note that Internet Explorer version 8.

In optimal habitats, these plants naturally grew in relatively dense stands, but required human intervention in order to be efficiently harvested in marginal zones. A BSR is likely to manifest as both an increased spectrum of food resources and an evenness in the exploitation of high- and low-value prey. Most importantly, Flannery argues that the need for more food in these marginal environments led to the deliberate cultivation of certain plant species, especially cereals. In terms of fauna, animal prey which was previously considered an inefficient use of resources (particularly small, fast mammals or fish) could now also be worthwhile. In other words, increasing scarcity made the extra effort necessary for survival. The broad spectrum revolution followed the ice age around 15,000 BP in the Middle East and 12,000 BP in Europe. Thus, the broad spectrum revolution set the stage for domestication and rise of permanent agricultural settlement. x will not be supported as of January 1, 2016.
