388 results about "Adaptive strategies" patented technology

The expression adaptive strategies is used by anthropologist Yehudi Cohen to describe a society’s system of economic production. Cohen argued that the most important reason for similarities between two (or more) unrelated societies is their possession of a similar adaptive strategy. In other words, similar economic causes have similar sociocultural effects.
