Una respuesta a estas condiciones ambientales desfavorables fue el emplazamiento de asentamientos más permanentes en ambientes lacustres estables. Este proceso va asociado a cambios económicos y sociales, que reflejan una incipiente complejidad social de las comunidades cazadoras recolectoras que habitaron el norte de Chile. 2010 artículo científico 0716-0925 https://www.redalyc.org/articulo.oa?id=31520182002 es http://www.redalyc.org/revista.oa?id=315 Estudios Atacameños application/pdf Universidad Católica del Norte Estudios Atacameños (Chile) Num.39
