Peking Man

life science Maturity 7-9 Next article →

Peking Man, scientifically known as Homo erectus pekinensis, was a subspecies of early humans.

They lived in what is now northern China during the Middle Pleistocene epoch. Their fossils were discovered in the Zhoukoudian cave site, located southwest of Beijing. This site is famous because it is the most productive Homo erectus site on Earth.

These findings were crucial for the development of Chinese anthropology. They also created a scientific dialogue between Eastern and Western researchers. For a long time, Peking Man was seen as a direct human ancestor. This supported the "Out of Asia" theory of human evolution.

The anatomy of Peking Man shows the classic features of Homo erectus. Their skulls were long and very heavily fortified with thick bone. A large bar of bone circled the crown of the skull. This bar crossed the brow ridge and the area over the ears. A feature called a sagittal keel also ran across the midline of the skull.

Their faces were protrusive, a condition known as midfacial prognathism. They had wide eye sockets and robust, chinless jaws. Their teeth were large, and their incisors were specifically shovel-shaped.

Brain volume was a key feature of their biology. It ranged from 700 to 1,200 cubic centimeters. This average of just over 1,000 cubic centimeters is within the range for modern humans.

Peking Man lived in a cool environment made of steppes and forests. They shared this landscape with many large animals. These included deer, rhinos, elephants, and bison. They also lived alongside buffalo, bears, wolves, and big cats.

The exact timing of their stay at Zhoukoudian is still debated. Evidence suggests they inhabited the cave from 800,000 to 230,000 years ago. This period included several cold glacial and warm interglacial cycles. Scientists are still trying to establish a precise chronology for their presence. Their ability to survive these temperature changes is a major topic of study.

Researchers debate how complex the society of Peking Man was. One major question is whether they were hunters or scavengers. If they were hunters, they might have made clothes to stay warm. Some evidence also suggests they may have controlled fire.

Controlling fire would have helped them survive frigid glacial periods. However, some scientists argue they might have just retreated south during the cold. Another mystery is whether they lived in the cave or were killed there. Some believe giant hyenas, known as Pachycrocuta, killed them and left their bodies in the cave.

Archaeologists have recovered over 100,000 pieces of stone tools from the site.

Most of these pieces are debitage, which is the waste material left from making tools. They also found simple choppers and flakes. Some more advanced tools were discovered as well, such as scrapers and possibly burins.

These tools show how these early humans interacted with their environment. The variety of tools helps scientists understand their daily activities and survival strategies.

The discovery of Peking Man began with Johan Gunnar Andersson in 1914. He was originally in China to map mineral deposits for the Swedish government. In 1918, an American teacher named John McGregor Gibb pointed him toward Zhoukoudian. Andersson returned in 1921 with paleontologists Walter W. Granger and Otto Zdansky. Zdansky found the first fossil, a human tooth, in 1921.

Later, Davidson Black helped name the species Sinanthropus pekinensis. In 1929, the Chinese anthropologist Pei Wenzhong found a nearly complete skullcap.

These discoveries involved many famous names in global science.

A tragic event occurred during the Second Sino-Japanese War in 1941. Scientists tried to move the fossils to the United States for safekeeping. The fossils were placed in two wooden footlockers. They were sent to a ship called the SS President Harrison. During the journey, Japanese warships attacked the ship. The ship ran aground, and the fossils disappeared.

No one knows exactly what happened to them. Some believe they are at the bottom of the sea. Others suggest they might be buried under a road or a parking lot in China. The mystery of the lost fossils remains one of science's greatest puzzles.
