When considering the pan-African process of human evolution in the Pleistocene it is important to review our understanding of climate on a regional scale, including heterogeneity due to regional variability in the relative strengths of forcing mechanisms. Research in the Kuruman Hills at the southern edge of the Kalahari in South Africa has recently provided new insights into the complexity and distinctiveness of southern African palaeoclimate. Here we compare these records, obtained from Kathu Pan, Wonderwerk Cave, and Mamatwan Mine, focusing on the presence of water bodies from c. 2 million years before present to the end of the Pleistocene. Through the synthesis of multiple proxies we create a picture of localized water availability as it would have affected hominin adaptation. These records are then framed within a larger discussion of regional climate and environmental change. The emerging record from the southern Kalahari suggests that the distribution of zones of rainfall seasonality varied significantly throughout the Pleistocene and a hominin presence is particularly found in association with wetter phases which supported lakes, springs and pans.

南非喀拉哈里南部的更新世环境

在考虑更新世人类进化的泛非过程时,重要的是要回顾我们对区域尺度气候的理解,包括由于强迫机制相对强度的区域变异而导致的异质性。最近,在南非喀拉哈里山脉南部边缘的库鲁曼山上的研究为了解南部非洲古气候的复杂性和独特性提供了新的见解。在这里,我们比较了从 Kathu Pan、Wonderwerk Cave 和 Mamatwan Mine 获得的这些记录,重点关注来自 c. 的水体的存在。200 万年前到更新世末期。通过综合多个代理,我们创建了局部可用水的图片,因为它会影响人类的适应。然后将这些记录纳入对区域气候和环境变化的更广泛的讨论中。来自喀拉哈里南部的新记录表明,整个更新世降雨季节性区域的分布变化很大,尤其是在支持湖泊、泉水和平底锅的湿润阶段中发现了人族的存在。
