Lost in the maze of Beijing’s history stands Zhoukoudian. This isn’t just any place. It’s the Peking Man Site a UNESCO World Heritage Site. Imagine stepping back millions of years. Picture Peking Man Homo erectus roaming these very caves. They lived here between 770000 and 230000 years ago. This incredible cave system in Fangshan District yielded astonishing discoveries. Not only Peking Man’s remains but also bones of giant short-faced hyenas.
The story of Zhoukoudian begins in 1918. Swedish geologist Johan Gunnar Andersson began exploring the region. Locals called it Chicken-bone Hill. They mistook rodent fossils for chicken bones. In 1921 Andersson and Walter Granger found Dragon Bone Hill. There Andersson noticed white quartz a mineral not native to the area. He knew this was significant. He exclaimed “Here is primitive man now all we have to do is find him”.
Excavations followed. Otto Zdansky unearthed two human teeth in 1921 and 1923. Davidson Black later identified them as a new species. Extensive digs revealed remains of about 45 individuals. They also found animal remains and stone tools. The oldest animal remains date back 690000 years. The tools are as old as 670000 years. Another authority dates them no earlier than 530000 years ago. The site was later reoccupied during the Upper Palaeolithic. Remains of Homo sapiens and their tools were also found in the Upper Cave.
The Zhoukoudian Project started in 1927. It was funded by the Rockefeller Foundation. Chinese archaeologist Li Jie oversaw the excavations. A tooth unearthed that fall led Black to propose a new species Sinanthropus pekinensis. More fossils followed including a juvenile jaw and an adult jaw. Pei Wenzhong discovered the first skullcap in 1929. He worked in a 40-meter crevasse in freezing weather. He used a hammer in one hand and a candle in the other. A second skullcap followed in 1930. By 1932 nearly 100 workers were employed daily.
Sadly the Japanese invasion of China halted excavations in 1937. The bulk of the findings were lost in 1941. They were never recovered. Fortunately Franz Weidenreich had made copies. Post-war excavations continued yielding more fossils and artifacts. Zhoukoudian remains one of the most fruitful sources of Middle Pleistocene era material. It offers a glimpse into the distant past a testament to human evolution. The story of Zhoukoudian is far from over. Its secrets continue to fascinate scientists and inspire awe in all who visit.
