New Paleolithic sites discovered in Hanzhong Basin, Central China

The catchment of Hanjiang River is regarded as one of the most important Paleolithic sites in central China. During 2009-2012, a scientific team led by Dr. WANG Shejiang, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences, conducted surveys and discovered two new Paleolithic open-air sites in the Hanzhong Basin. Researchers unearthed 252 stone artifacts, and reported the finding in the journal of Acta Anthropologica Sinica 2014 (2). This study indicates hominins already occupied the Hanzhong Basin from approximately 600000 years ago, and provides important data for the study of human adaptive strategies and patterns in this region and as well as the Palaeolithic culture and human behavior in East Asia.

Two new Paleolithic open-air sites, Hejialiang and Yaochangwan, are located in the upper valley of Hanjiang River in the southern piedmont of the Qinling Mountains, central China. The lithic assemblage analysis suggests that the stone artifacts were made of local raw materials of pebbles/cobbles which derived from the riverbank alluvial deposits of the Hanjiang River. The lithic samples from the Hejialiang site frequently made of quartz,

Graywacke, and igneous rock, but infrequently made of quartzite and silicon limestone. The lithics of the Yaochangwan site more frequently made of quartz, quartzite and igneous rock, but infrequently made of sandstone and silicon limestone. ...

Society bloomed with gentler personalities, more feminine faces:

A composite image shows the facial differences between an ancient modern human with heavy brows and a large upper face and the more recent modern human who has rounder features and a much less prominent brow. The prominence of these features can be directly traced to the influence of the hormone testosterone.

Modern humans appear in the fossil record about 200,000 years ago, but it was only about 50,000 years ago that making art and advanced tools became widespread.

A new study appearing Aug. 1 in the journal Current Anthropology finds that human skulls changed in ways that indicate a lowering of testosterone levels at around the same time that culture was blossoming.

"The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at the same time that we developed a more cooperative temperament," said lead author Robert Cieri, a biology graduate student at the University of Utah who began this work as a senior at Duke University.

The study, which is based on measurements of more than 1,400 ancient and modern skulls, makes the argument that human society advanced when people started being nicer to each other, which entails having a little less testosterone in action.

Heavy brows were out, rounder heads were in, and those changes can be traced directly to testosterone levels acting on the skeleton, according to Duke anthropologist Steven Churchill, who supervised Cieri's work on a senior honors thesis that grew to become this 24-page journal article three years later. ...

...So in the far future, men and women will be completely indistinguishable?
