While there is good evidence for the first arrival in Eurasia around 50-45ka, the fossil record is extremely scarce with regard to earlier representatives. A partial calvaria discovered at Manot Cave (Western Galilee, Israel) dated to >55 ka by uranium–thorium dating was recently described. Since then, other findings indicated an early dispersal of modern humans out-of-Africa between 194 and 177ka (Misliya-1) or possibly even earlier at 210ka (Apidima 1), and a quite long existence of Homo sapiens in Africa (Jebel Irhoud, ~300ka). While the faces of these early Homo sapiens appear quite modern, the shape of the braincase seems to lack behind, reaching the modern state only around after 35ka. Here, new data and approaches were applied to the Manot 1 calvaria. The ecto- and endocranial shape analyses based on micro-computed tomography data and a landmark-semilandmark approach using multiple reconstructions of the incomplete calvaria confirm that Manot 1 is unequivocally modern human. Its endocranial shape is markedly different from the earliest known Homo sapiens and close to the Levantine Qafzeh/Skhul assemblage (120-90ka) as well as modern humans, but still shows some deviations from both groups. The absence of other Homo sapiens fossils in the Levant between the Qafzeh/Skhul and Manot populations is not supportive for the hypothesis of a continuous occupation or the local evolution of modern humans. It suggests that Manot 1 represents a population migrating out-of-Africa and reaching the Levantine corridor during warmer and wetter climatic conditions over the Northern Sahara and the Mediterranean. Manot 1 shows that both modern humans and Neanderthals (e.g. Kebara, Amud) contemporaneously inhabited the Levant during the Middle to Upper Paleolithic interface. The endocranial shape of Manot 1 might indicate that this population had not yet fully reached the brainshape of modern humans evident after 35ka.

Twenty terrestrial and 20 marine climate proxies are used to identify long-term trends in humidity involving transitions from humid to arid conditions and vice versa. The frequency distribution of episodes of relative aridity across these records is calculated for the period 6300e2000 BC, so that the results may be interpreted in the context of the established arid episodes associated with RCC around 6200 and 2200 BC (the 8.2 and 4.2 kyr events). We identify two distinct episodes of heightened aridity in the early-mid 4th, and late 4th millennium BC. These episodes cluster strongly at 3600e3700 and 3100e3300 BC. There is also evidence of localised aridity spikes in the 5th and 6th millennia BC. These results are used as context for the interpretation of regional and local archaeological records with a particular focus on case studies from western Syria, the middle Euphrates, southern Israel and Cyprus. Interpretation of the records involves the construction of plausible narratives of humaneclimate interaction informed by concepts of adap- tation and resilience from the literature on contemporary (i.e. 21st century) climate change and adap- tation. The results are presented alongside well-documented examples of climatically-influenced societal change in the central and eastern Sahara, where detailed geomorphological studies of ancient envi- ronments have been undertaken in tandem with archaeological research. While the narratives for the Near East and Eastern Mediterranean remain somewhat speculative, the use of resilience and adaptation frameworks allows for a more nuanced treatment of humaneclimate interactions and recognises the diversity and context-specificity of human responses to climatic and environmental change. Our results demonstrate that there is a need for more local environmental data to be collected ‘at source’ during archaeological excavations.
