The successful analysis of LiDAR data for archaeological research requires an evaluation of effects of different vegetation types and the use of adequate visualization techniques for the identification of archaeological features. The Ceibal-Petexbatun Archaeological Project conducted a LiDAR survey of an area of 20 × 20 km around the Maya site of Ceibal, Guatemala, which comprises diverse veget...

The Middle Stone Age (MSA) of southern Africa, and in particular its Still Bay and Howiesons Poort lithic traditions, represents a period of dramatic subsistence, cultural, and technological innovation by our species, Homo sapiens. Climate change has frequently been postulated as a primary driver of the appearance of these innovative behaviours, with researchers invoking either climate instabil...

0278 © 2002 All rig Archaeological tests of hypotheses drawn from foraging theory face a unique set of challenges. Simple foraging models, such as the diet breadth model, rely on assumptions that are clearly violated in the human case. Testing is complicated by the indirect nature of the observations used to reconstruct environment and behavior and by the cumulative nature of the archaeological...

Finding solutions to the entangled problems of human population growth, resource exploitation, ecosystem degradation, and biodiversity loss is considered humanity’s grand challenge. Small and isolated societies of the past, such as the Rapanui of Easter Island, constitute ideal laboratories for understanding the consequences of human-driven environmental degradation and associated crises. By in...

Hyperostosis frontalis interna (HFI) is a disease characterized by excess bone growth on the internal lamina of the frontal bone and, occasionally, other cranial bones. Although the disease is fairly common in modern populations, its etiology is poorly understood. Hyperostosis frontalis interna has been identified in antiquity, primarily in the Old World, but with a much lower frequency than in...

The archaeological record shows that typically human cultural traits emerged at different times, in different parts of the world, and among different hominin taxa. This pattern suggests that their emergence is the outcome of complex and nonlinear evolutionary trajectories, influenced by environmental, demographic, and social factors, that need to be understood and traced at regional scales. The...
