New research argues that the theories of extensive savannah formations in the South-western Amazonia during the current Holocene period are based on a false interpretation of the connection between charcoal accumulation and natural fires due to drier climatic periods. These interpretations have not taken into account the millennial human presence in Amazonia.
One of world's earliest examples of art, the enigmatic `Venus' figurines carved some 30,000 years ago, have intrigued and puzzled scientists for nearly two centuries. Now a researcher from the University of Colorado Anschutz Medical Campus believes he's gathered enough evidence to solve the mystery behind these curious totems.
A study conducted by the UPV/EHU's IBeA group shows that pyroclasts may be putting the conservation of the paintings of Pompeii at risk. Specifically, the ions leached from these materials and the underground ion-rich waters from the volcanic rocks may be causing the salts in the paintings to crystallise. In addition, the use of fluorine as a marker is proposed to monitor in situ the extent of the damage sustained by the murals.
By analyzing sediment cores taken from six sites in southern Greece, an international team of researchers identified trends in cereal, olive, and vine pollen indicating structural changes in agricultural production between 1000 BCE and 600 CE. In a study published The Economic Journal, the researchers combine varying fields of scientific research to provide evidence for a market economy in ancient Greece characterized by integrated agricultural production and a major expansion of trade
Neanderthal thumbs were better adapted to holding tools in the same way that we hold a hammer, according to a paper published in Scientific Reports.
New WSU research sheds light on the production of an 800-year-old turkey feather blanket and explores the economic and cultural aspects of raising turkeys to supply feathers in the ancient Southwest.
Blame it on the bison. If not for the wooly, boulder-sized beasts that once roamed North America in vast herds, ancient people might have looked past the little barley that grew under those thundering hooves. But the people soon came to rely on little barley and other small-seeded native plants as staple food.
Chemical analyzes of a black spot in a diary shed new light on the destiny and tragic death of legendary Inuit polar expedition member Jørgen Brønlund in Northeast Greenland in 1907.
The Iberian Peninsula has one of the richest paleontological records in Western Europe. However,"there were generally only scarce indications of the collection and use of fossils at Iberian sites during Prehistory, and thus the documentation of this behaviour presented an anomalous situation compared to other regions of Europe, where numerous studies have been published on this practice.
Excavations on the south coast of South Africa have uncovered evidence of human occupations from the end of the last ice age, approximately 35,000 years ago, through the complex transition to the modern time, known as the Holocene and adaptions that were key to our species ability to survive wide climate and environmental fluctuations.
