ScienceDaily (Mar. 13, 2009) — 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.

A dating method developed by a Purdue University researcher allowed a more accurate determination of the age of the Zhoukoudian, China, site of remains of Homo erectus, commonly known as "Peking Man." The site was found to be 680,000-780,000 years old. Earlier estimates put the age at 230,000-500,000 years old.
