Pre-European Plant Consumption and Cultural Changes in the Coastal Lluta Valley, Atacama Desert, Northern Chile (Ca. 5140–390 Cal Yr BP). The introduction of domesticated plants into ancient hunting and gathering economic systems expanded and transformed human societies worldwide during the Holocene. These transformations occurred even in the oases and hyperarid environments of the Atacama Desert along the Pacific coast. Human groups inhabiting this desert incorporated adjacent habitats to the semi-tropical valleys through transitory or logistic camps like Morro Negro 1 (MN-1), in the Lluta valley (~12 km from the littoral in northernmost Chile), into their settlement patterns. During the earliest occupation (Late Archaic period, 5140–4270 cal yr BP) people collected and consumed wild plants, although crops such as Lagenaria were present. Following a gap of more than 2000 years between 4270 and 1850, people returned and introduced new domesticated plants at the site (Gossypium, Zea mays, Capsicum), which displaced the use of wild reed (Schoenoplectus) rhizomes as the chief staple during the first occupation. This change in food consumption was linked to the transformations that took place during the Archaic-Formative transition, but did not entirely shift the ways of life of these coastal marine hunter-gatherers.

智利北部阿塔卡马沙漠的卢塔海岸沿海地区的欧洲前植物消费和文化变化（约5140–390 Cal Yr BP）。在全新世时期，将驯化的植物引入古代的狩猎和采集经济体系，在世界范围内扩大并改变了人类社会。这些变化甚至发生在太平洋沿岸阿塔卡马沙漠的绿洲和高干旱环境中。居住在这片沙漠中的人类群体通过诸如Lluta谷（距智利最北部沿岸约12公里）的Morro Negro 1（MN-1）的短暂或后勤营地，将邻近的栖息地纳入了半热带山谷。在最早的占领时期（古代晚期，5140-4270 cal BP），人们收集和食用野生植物，尽管农作物如存在拉格纳里亚。在4270年至1850年之间有2000多年的差距之后，人们返回并在该地点引入了新的驯化植物（棉，玉米，辣椒），这在第一时期就取代了使用野生芦苇（Schoenoplectus）的根茎作为主要主食占用。粮食消费的这种变化与古形成过渡时期发生的转变有关，但并没有完全改变这些沿海海洋狩猎采集者的生活方式。
