" Forget persistence hunting: salmon eaters need only sit at streamside and rake it in, literally tons of high-quality protein. But each of those salmon, one of the world’s most peripatetic species, has ranged thousands on thousands of miles across diverse marine and aquatic environments during its short life cycle. That is, each fish has sampled and bioaccumulated a diverse collection of micronutrients lacking in a terrestrial diet. Remember the value of diversity realized by nomads hunting across diverse environments. Nomads eating a nomadic marine species takes that idea up a notch: nomadism squared. "
