Note: Lomax and Arensberg discuss revisions and improvements in Murdock typology. For example, Zuni formerly classed with Asian farmers because had irrigation, now classed as incipient farmers. Which came first hunting or fishing (as opposed to shellfish collecting)? Fishermen use more technology (e.g., boats). Specialization: intensive knowledge of one food source doesn't preclude knowledge of other food sources. Relevant distinctions: Varieties of pastoralists - nomads, mixed flock, unspecialized, consumption of animal products as well as meat. Plow versus digging stick. Fixed fields versus slash and burn. Mediterranean combination of fixed fields, cereals, use of plough, with milking. Presence of cash crops. Arensberg: Europeans are distintive from Asians in cultivation of hay for animal fodder. Complex European agriculture mixture requires scheduling and planning. Inadequacies of Murdock typology.
