Humans in Africa’s wet tropical forests 150 thousand years ago
Eslem Ben Arous et al.
Nature, forthcoming
Abstract:
Humans emerged across Africa shortly before 300 thousand years ago (ka). Although this pan-African evolutionary process implicates diverse environments in the human story, the role of tropical forests remains poorly understood. Here we report a clear association between late Middle Pleistocene material culture and a wet tropical forest in southern Côte d’Ivoire, a region of present-day rainforest. Twinned optically stimulated luminescence and electron spin resonance dating methods constrain the onset of human occupations at Bété I to around 150 ka, linking them with Homo sapiens. Plant wax biomarker, stable isotope, phytolith and pollen analyses of associated sediments all point to a wet forest environment. The results represent the oldest yet known clear association between humans and this habitat type. The secure attribution of stone tool assemblages with the wet forest environment demonstrates that Africa’s forests were not a major ecological barrier for H. sapiens as early as around 150 ka.
Climate change in Europe between 90 and 50 kyr BP and Neanderthal territorial habitability

PLoS ONE, February 2025
Abstract:
After having lived as the dominant human species in Europe for over 200 kyr, Homo neanderthalensis (the Neanderthals) disappeared around 40 kyr BP (Before Present). Competition with Homo sapiens, who arrived in Europe around the same time, is often invoked to explain this extinction. Others have argued that climate change may have reduced the living space of this population making its disappearance more rapid. In order to test the climate change hypothesis we modelled the Neanderthals’ ecological niches in Europe between 90 and 50 kyr BP through paleoenvironmental reconstructions and Eco-Cultural Niche Modelling. We selected five environmental variables (orographic height, mean annual precipitation, mean temperature of the coldest month, carrying capacity and friction) from climate model simulations of 5 periods between 90 and 50 kyr BP in Europe. We used Structural Similarity (SSIM) index to compare the probability maps of suitable niches to Neanderthals performed by Maxent. After a strong initial environmental change between the first (P1 = 90 to 83 kyr BP) and second (P2 = 83 to 69 kyr BP) periods, our results show that large areas highly suitable for Neanderthal occupation persisted across Europe. As our results show an increase/stability of the areas suitable to Neanderthals, the question of the cause of the decrease or displacement of the Neanderthal population towards southern Europe after this climatic change remains open.
Codes in the Making. A New Appraisal of Neolithic Imagery in Southwest Asia
Mattia Cartolano & Silvia Ferrara
Cambridge Archaeological Journal, forthcoming
Abstract:
Marks and figurative representations have been recognized as crucial socio-cognitive components that contributed to the transition from foraging to farming of the Neolithic in southwest Asia, during a period in which communities adopted novel social interactions and economic strategies. This article investigates image production and the trajectories tied to the creation of visual codes. We show that since the early Neolithic phases (c. 9700–6600 cal. BC) societies in southwest Asia engaged with specific symbols and created narrative and operational semasiographies, intended to serve as key communicative devices that functioned as community ties and contributed to social interaction across distant groups.
The Collector Hypothesis: Who Benefits More from Art, the Artist or the Collector?
Piotr Sorokowski et al.
Human Nature, December 2024, Pages 397–410
Abstract:
Human fascination with art has deep evolutionary roots, yet its role remains a puzzle for evolutionary theory. Although its widespread presence across cultures suggests a potential adaptive function, determining its evolutionary origins requires more comprehensive evidence beyond mere universality or assumed survival benefits. This paper introduces and tests the Collector Hypothesis, which suggests that artworks serve as indicators of collectors’ surplus wealth and social status, offering greater benefits to collectors than to artists in mating and reproductive contexts. Our study among Indigenous Papuan communities provides preliminary support for the Collector Hypothesis, indicating that, compared to artists, collectors are perceived as having higher social status and greater attractiveness to women. These findings provide unique insights into Papuan communities and contribute to the ongoing discussion about art’s adaptive significance of art by suggesting that artistic capacities may benefit not only creators but also those who accumulate and display art. Further research in diverse cultural contexts is needed for a comprehensive understanding of this interplay.
Unveiling Materiality: Investigating Cuneiform Tablet Production Tradition in Egypt through Amarna Tablets
Jana Mynářová
Cambridge Archaeological Journal, forthcoming
Abstract:
This article examines a frequently overlooked aspect of cuneiform writing in Egypt: the materiality and technology involved in the production of cuneiform tablets, with a particular focus on the process of tablet firing. It is argued that firing was an integral part of tablet production that required learning and practice by the Amarna scribes. The successful firing of tablets to temperatures around 800°C is attributed to the robust and longstanding tradition of tablet manufacture in Mesopotamia, Anatolia, northern Syria and Hazor. In contrast, the lower firing temperatures observed in tablets from Egypt, Alašiya and much of the Levant are associated with the production and firing of cuneiform tablets as a recent technological innovation that required thorough mastery.
