The expression adaptive strategies is used by anthropologist Yehudi Cohen to describe a societyâs 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.astoralists live in North Africa, the Middle East, Europe, Asia, and sub-Saharan Africa. These herders are people whose activities focus on such domesticated animals such as cattle, sheep, goats, camels, yak, and reindeer.
