“…In addition, a regional net primary productivity layer is defined from LOVECLIM climate reconstruction 7 , 26 as an indicator of relative ecological carrying capacity of the ecosystem 7 , 41 (Supplementary Fig. 2 ) and low cost areas are enforced along coastal regions 42 , 43 . These layers are then amalgamated to create a normalised physiographic resistance map that defines how amenable a region is for mobility, with high values representing regions hindering movement (Supplementary Fig.…”

“…This predicted map suggests that human settlers would have dispersed predominantly across the continental interior along rivers and river basins corridors on both sides of Lake Carpentaria (Fig. 3 ) and highlights a preferential north-south route rather than a coastal one 42 , 43 , 66 . Yet, we find some regions with relatively low walked distances along the northern and central coastlines of Western Australia, the Great Australian Bight (South Australia), and in Queensland (Fig.…”

“…Despite the limitations, analysis of migration and occupation patterns from our results shows that all known archaeological sites are visited by modelled walkers with calculated peopling of Sahul velocities within the range proposed in other studies 2 , 8 , 63 . No statistically optimal superhighways 2 , 9 nor major preferential coastal routes 42 , 43 , 66 arise from our KDE. Instead, it either advocates for a spread on both sides of Lake Carpentaria 4 , 6 along major drainage systems when considering a northern entry (Fig.…”

The route and speed of migration into Sahul by Homo sapiens remain a major research question in archaeology. Here, we introduce an approach which models the impact of the physical environment on human mobility by combining time-evolving landscapes with Lévy walk foraging patterns, this latter accounting for a combination of short-distance steps and occasional longer moves that hunter-gatherers likely utilised for efficient exploration of new environments. Our results suggest a wave of dispersal radiating across Sahul following riverine corridors and coastlines. Estimated migration speeds, based on archaeological sites and predicted travelled distances, fall within previously reported range from Sahul and other regions. From our mechanistic movement simulations, we then analyse the likelihood of archaeological sites and highlight areas in Australia that hold archaeological potential. Our approach complements existing methods and provides interesting perspectives on the Pleistocene archaeology of Sahul that could be applied to other regions around the world.

Since the 19th century, the study of shell middens has played an important role in archaeological research. Shell midden and broader coastal archaeology have transformed our understanding of human relationships with aquatic habitats, demonstrating the importance of marine environments to human evolution and ecology, the colonization of islands and establishment of maritime trade networks, changing social and political dynamics, and a variety of other issues. During the past two decades, shell midden research has greatly increased, marking an exciting time for new discoveries and heightened collaboration with Indigenous communities. Several key research trends in shell midden archaeology during the past 10–15 years include research on site distribution and temporality, underwater archaeology, historical ecology, terraforming, landscape legacies, and community collaboration. These research trends demonstrate the ways in which shell midden archaeologists are shaping our understanding of the human past and environmental change around the world.
