A hidden Murray River rockshelter speaks volumes about local Aboriginal and European settlement in the Riverland, with symbols of conflict -- including a swastika symbol -- discovered in Aboriginal rock art. The engravings studied in 188 engravings in a remote South Australian rockshelter are a stark reminder of colonial invasion and the strife brewing in Europe ahead of World War Two, Flinders University archaeologists have revealed.
Research by anthropologists at the University of Kent has identified hand use behavior in fossil human relatives that is consistent with modern humans. The human lineage can be defined by a transition in hand use. Early human ancestors used their hands to move around in the trees, like living primates do today, whereas modern human hands have evolved to primarily perform precision grips.
Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still debated. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city's rapid expansion.
Today Boa snakes have a patchy distribution in the islands that form the Lesser Antilles in the Caribbean Sea, but the constrictors are nearly absent from archaeological deposits in the region. Whether this scarcity is due to biological or cultural factors remains unknown. The current study describes the first Boa finds on Martinique, Basse-Terre and La Désirade, and provides a new hypothesis concerning the relationship between indigenous human populations and Boa prior to Western colonization.
Three hundred-year-old administrative documents from the Roman government, granting residents permission to repair damage to their buildings, can help modern-day seismologists calculate intensities for a notable sequence of earthquakes that struck central Italy in 1703.
Due to the improvement and increased use of geochemical fingerprinting techniques during the last 25 years, the archaeological compositional data of stone tools has grown exponentially. The Pofatu Database is a large-scale collaborative project that enables curation and data sharing. The database also provides instrumental details, analytical procedures and reference standards used for calibration purposes or quality control. Thus, Pofatu ensures reproducibility and comparability between provenance studies.
History shows us that power tends to corrupt; a team of Swiss and German researchers have recently examined historical examples of large-scale business fraud and misconduct at the highest-levels of government in order to highlight how leaders sometimes lose all sense of morality. Inflicting serious harm on their company or society in this new study in The Leadership Quarterly, published by Elsevier.
Historic records from weather stations show that rainfall patterns in Scotland were affected by charge in the atmosphere released by radiation from nuclear bomb tests carried out in the 1950s and '60s.
The question of whether democracies behave differently from non-democracies is a central, and intense, debate in the field of international relations. Two intellectual traditions -- liberalism and realism -- dominate. Liberals argue that democracies do indeed behave differently, while realists insist that regime type and ideology are of little relevance in understanding foreign policy behavior. Arman Grigoryan, a faculty member in the Department of International Relations at Lehigh University has contributed to this debate with a recent article in a top journal, International Security.
An international team of researchers including the University of Adelaide, has completed the first large-scale study of DNA belonging to ancient humans of the central Andes in South America and found early genetic differences between groups of nearby regions, and surprising genetic continuity over thousands of years.
