德鲁兹沼泽是约旦东北部的泉水湿地，在 20 世纪 80 年代末完全干涸。地下水位的干燥和随后的下降使得研究沼泽地层和寻找史前职业成为可能。在本文中，我们结合了对前德鲁兹沼泽底部八个地层剖面的详细沉积学分析，重建了中更新世以来古人类所使用的景观。结果表明，过去 350 ka 内可用水量的波动对湿地的大小和深度产生了巨大影响。更新世时，德鲁兹沼泽的人类活动与湿地面积缩小时相对干燥的气候条件相对应，这表明德鲁兹沼泽在不利的气候条件下充当了古人类的沙漠避难所。这种避难所对于叙利亚-阿拉伯沙漠中的古人类人口统计、连续性和/或灭绝具有重要意义。此外，德鲁兹沼泽位于瓦迪锡尔汉洼地的北端，该洼地将黎凡特走廊与西部连接起来，将阿拉伯半岛与东南部连接起来。因此，在潮湿的气候下，德鲁兹沼泽周围的古湖泊和河流网络可能为分布在非洲、欧亚大陆和阿拉伯半岛之间的古人类提供了一条额外的内陆路线。
The Druze Marsh is a spring‐fed wetland in northeast Jordan that dried out completely in the late 1980s. This drying and subsequent drop in the water table permitted study of the marsh stratigraphy and a search for prehistoric occupations. In this paper, we combine detailed sedimentological analysis of eight stratigraphic sections in the bed of the former Druze Marsh to reconstruct the landscapes used by hominins since the Middle Pleistocene. The results show that fluctuation in water availability over the past 350 ka had dramatic impacts on the size and depth of the wetlands. Pleistocene occupations in the Druze Marsh correspond to relatively dry climatic conditions when the wetland was reduced in size, suggesting the Druze Marsh acted as a desert refugium for hominins during adverse climatic conditions. Such refugia have important implications for hominin demography, continuity, and/or extinction in the Syro‐Arabian Desert. Moreover, the Druze Marsh is positioned at the north end of the Wadi Sirhan depression that connects the Levantine Corridor to the west and Arabian Peninsula to the southeast. Therefore, during wetter climates, paleolakes and river networks around the Druze Marsh may have provided an additional inland route for hominins dispersing between Africa, Eurasia, and the Arabian Peninsula.
