Article
he Weichselian glaciation is characterized by significant ocean circulation variations starting from ∼115 thousand years ago (ka) and terminating at ∼11.5 ka. The early Weichselian (115–74 ka), especially marine isotope stage (MIS) 5a at 85–74 ka, provides a window for understanding the linkage between the European westerlies and Mediterranean clim...

The circum-Mediterranean region is the cradle of ancient civilizations that had their roots in the Holocene. Climate change has been considered a key element that contributed to their rise or fall. The Roman Warm Period (RWP), 200 B.C. to 400 A.D., was the warmest period in Europe during the last two thousand years. Hydroclimatic change at the end...

The first " Out of Africa " migrations represent a seminal event in the history of humankind. At the gates of Europe, the first appearance of Hominins is recorded in Georgia, 1.8 million years ago (Ma); however, the picture of migration across the continent remains incomplete. Vallonnet Cave (France) is a Lower Paleolithic prehistoric site with tra...
Article
The origin of modern humans continues to be one of the most heavily debated topics within paleoanthropology. Eastern Asia, and particularly China, is a geographic region that is taking on increasing importance in resolving some of these debates (Stringer, 2002; Wu, 2004; Trinkaus, 2005; Norton and Jin, 2009; Bae, 2010; Liu et al., 2010a,b). The reg...

Article
Sauvet et al. (in press) present a partial description of the Uranium-series or 230Th/234U dating method, which leads them to criticize this dating tool and claim that this method provides “an extremely wide range of uncertainty providing a weak base upon which to build scientific reasoning”. In this comment, we discuss three concepts introduced by...
