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.
For example, there are clear similarities among societies that have a foraging (hunting and gathering) strategy. Cohen developed a typology of societies based on correlations between their economies and their social features. His typology includes these five adaptive strategies:
foraging
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavi ...

s. According to Cohen, horticulture is cultivation that does not make any intensive use of the usual factors of production: land, labor, capital, and machinery. Agriculture is a type of cultivation that requires more labor than horticulture does, because it uses land intensively and continuously. The greater labor demands associated with agriculture reflect its use of domesticated animals,
