“…Under what mechanisms did the Chinchorro populations supply themselves with animal skins and fiber of camelids, chinchilla and vizcacha, or with manganese and various lithic raw materials? It is possible that they obtained these materials through interregional exchanges with Andean hunter-gatherers (Núñez, Zlatar, & Núñez, 1975;Núñez & Dillehay, 1979;Santoro & Núñez, 1987;Santoro, 1989;Castillo & Sepúlveda, 2015;Sepúlveda et al, 2013;Tripcevich & Contreras, 2013;Herrera et al, 2015), or directly through travel to the highlands (Schiappacasse & Niemeyer, 1975;Sandweiss et al, 1998;Standen et al 2004;Sandweiss, 2008;Sandweiss & Rademaker, 2011). Alternatively, it has been suggested that Andean huntergatherers came down to the coast to exchange goods with coastal populations (Lynch, 1973).…”
