The Last Glacial Maximum in the Tropics: Human Responses to Global Change, 30–10 ka - Journal of World Prehistory The world at 18,000 BP, published by Gamble and Soffer (The world at 18,000 BP. Vol. 2: low latitude, Unwin Hyman, 1990), represents the first, and so far the only, attempt at characterising and discussing the impact of the Last Glacial Maximum (LGM) on human societies on a global scale. At the time, they highlighted that research and data on the LGM in southern latitudes and the tropics in particular were scant. Since 1990, however, many sites dated to the LGM and located in tropical latitudes have been published. Many paradigms have changed regarding the peopling of the Americas, which allows the archaeology of this continent to be integrated into global scale studies of the LGM. The development of Pleistocene archaeology in tropical contexts, in parallel with methodological advances in cultural, geosciences and palaeoenvironmental studies have strongly reshaped what we know of the antiquity of human occupation in tropical regions and specific human–environment interactions. This article provides for the first time a pan-tropical perspective on the impact of the LGM on human groups living within the tropical latitudes, drawing from case studies in Southeast Asia, Africa and South America, specifically regions which have up until now never been discussed together. To this end, we focus on six different tropical regions between 30 and 10 ka. We present the archaeological and paleoenvironmental data available in these areas, along with proposed relationships for variations in these two records. Finally, we discuss at the regional scale the presence or absence of human changes (site density and techno-cultural change or continuity) before, during and immediately after the LGM.

How did populations in tropical regions cope with the global climatic change around the LGM?

While the tropics are often perceived as having been less impacted by the LGM, we show that -as is often the case - it is more complex than it seems!

Our new paper on 3D GM has all the models and script available for others to apply our method. We use it to demonstrate interregional variability of Nubian Levallois cores but it has broader potential for lithic studies #openscience #archaeology #3DGM @icarehb.bsky.social @jmcascalheira.bsky.social

Earliest evidence for humans in rainforests New research shows that humans lived in African rainforests 150,000 years ago. This is more than twice as early than previously thought.

I am so thrilled to share with you this project gallery published today on @antiquityj.bsky.social summarizing our research led by me and N. Aouadi in central Tunisia. We present here the first results of our project to study Acheulean and Middle Stone Age in this little-known part of North Africa!

Something special for the lithophiles for #FlintFriday and #FieldFriday - two ends of the Levallois spectrum from my survey yesterday in Luxor. I’ve never seen anything quite like either of them 🤩
