Wiens has a Ph D in Physics, with a minor in Geology.His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating."Many of the existing data methods rely on the availability of volcanic rock, which the Zhoukoudian site does not have.This method provides a new tool to provide insight into places where dating was previously limited." A paper detailing the work is featured on the cover of the current issue of Nature. Antón, associate professor in the Center for the Study of Human Origins at New York University said this discovery indicates "Peking Man" was somehow behaviorally able to cope with the cold environment.They analyzed four stone tools and six sediment samples from the site."This was the first dating of this kind to be used in an early hominid site in China," Granger said.Uranium is the heaviest and last naturally occurring element in the periodic table.The periodic table is a chart that shows how chemical elements are related to each other.

We will use this comparison to assess the reaction of the Antarctic Ice Sheet to the warming of the last termination (this work is explained in my other two field reports on Hatherton and Darwin Glaciers, Antarctica). "There is evidence that had physically adapted to the cold, but they probably also had to be doing something in terms of behavior to handle the cold of a glacial period in northern China," she said."There isn't good evidence of fire or any kind of skins or clothing, but evidence of such things doesn't last long and wouldn't be recorded particularly well in the archeological record.In January, we traveled from Christchurch to Twizel, a town southwest of Lake Pukaki. The Role of Ocean-Atmosphere reorganizations in glacial cycles. From our base in Twizel, we spent a month in the region west of Lake Pukaki mapping the glacial landforms deposited by the former Pukaki Glacier. A new dating method has found that "Peking Man" is around 200,000 years older than previously thought, suggesting he somehow adapted to the cold of a mild glacial period.
