Located about 42 kilometers southwest of Beijing, the Zhoukoudian cave system has been on the UNESCO World Heritage List since 1987. With a history stretching back approximately 750,000 to 200,000 years, it holds critical importance for understanding early human evolution.
Important fossils were unearthed during excavations in the region in the 1920s and 1930s. The name "Peking Man" given to these remains does not stem from a historical figure, but entirely from its geographical location. Because the fossils were found within the borders of Beijing, they are known by this name; in scientific literature, however, they are referred to as Homo erectus pekinensis, representing a sub population of the Homo erectus species in Asia.
The value of Zhoukoudian is not limited to these fossils alone; ash layers and burnt bones identified on the cave floors reveal that fire, one of the greatest turning points in human history, was brought under conscious control. The use of fire for cooking food facilitated digestion, increased the body's energy efficiency, and accelerated brain development, breaking new ground in human evolution.
Unfortunately, most of the original fossils obtained during the excavations were lost in the chaos of World War II. Therefore, today scientists have to settle for examining the precise casts prepared during that period.
