Homo erectus pekinensis

Peking Man (now in pinyin Beijing Man), also called Sinanthropus pekinensis (currently Homo erectus pekinensis), is an example of Homo erectus. A group of fossil specimens was discovered in 1923-27 during excavations at Zhoukoudian (Chou K'ou-tien) near Beijing (Peking), China. More recently, the finds have been dated from roughly 500,000 years ago.^[1]

Discovery and identification

Swedish geologist Johan Gunnar Andersson and American palaeontologist Walter W. Granger came to Zhoukoudian, China in search of prehistoric fossils in 1921. They were directed to the site at Dragon Bone Hill by local quarry men, where Andersson recognised deposits of quartz that were not native to the area. Immediately realising the importance of this find he turned to his colleague and announced, “Here is primitive man, now all we have to do is find him!”^[2]

Excavation work was begun immediately by Andersson's assistant Austrian palaeontologist Otto Zdansky, who found what appeared to be a fossilised human molar. He returned to the site in 1923 and materials excavated in the two digs were sent back to Uppsala University in Sweden for analysis. In 1926 Andersson announced the discovery of two human molars found in this material and Zdansky published his findings.^[3]

Davidson published his analysis in the journal Nature, identifying his find as belonging to a new species and genus which he named Sinanthropus pekinensis, but many fellow scientist were sceptical of such an identification based on a single tooth and the Foundation demanded more specimens before they would give an addition grant.^[4]

A lower jaw, several teeth and a skull fragments were unearthed in 1928. Black presented these finds to the Foundation and was rewarded with an $80,000 grant that he used to establish the Cenozoic Research Laboratory.

Excavations at the site from under the supervision of Chinese archaeologists Yang Zhongjian, Pei Wenzhong and Jia Lanpo uncovered 200 human fossils (including 6 nearly complete skullcaps) from more than 40 individual specimens. These excavation came to an end in 1937 with the Japanese occupation.

Fossils of the Peking Man were placed in the safe at the Cenozoic Research Laboratory of the Peking Union Medical College. Eventually, in November 1941, secretary Hu Chengzi packed up the fossils so they could be sent to USA for safekeeping until the end of the war. They vanished en route to the port city of Qinghuangdao. They were probably in possession of a group of US marines whom the Japanese captured when the war began between Japan and USA.

Various parties have tried to locate the fossils but, so far, without result. In 1972, a US financier Christopher Janus promised a $5,000 (U.S.) reward for the missing skulls; one woman contacted him, asking for $500,000 (U.S.) but she later vanished. In July 2005, the Chinese government founded a committee to find the bones to coincide with the 60th anniversary of the end of World War II.

There are also various theories of what might have happened, including a theory that the bones had sunk with a Japanese ship Awa Maru in 1945.^{citation needed}

Subsequent Research

Excavations at Zhoukoudian resumed after the war, and parts of another skull were found in 1966. To date a number of other partial fossil remains have been found. The Peking Man Site at Zhoukoudian was listed by UNESCO as a World Heritage Site in 1987.^[5]

Paleontological conclusions

The first specimens of Homo erectus had been found in Java in 1891 by Eugene Dubois, but were dismissed by many as the remains of a deformed ape. The discovery of the great quantity of finds at Zhoukoudian put this to rest and Java Man, who had initially being named Pithecanthropus erectus, was transferred to the genus Homo along with Peking Man.^[6]

Contiguous findings of animal remains and evidence of fire and tool usage, as well as the manufacturing of tools, were used to support H. erectus being the first "faber" or tool-worker. The analysis of the remains of "Peking Man" led to the claim that the Zhoukoudian and Java fossils were examples of the same broad stage of human evolution. This is also the official view of the Chinese Communist Party.^{citation needed}

Relation to modern Chinese people

Some Chinese paleoanthropologists have asserted in the past that the modern Chinese are descendants of the Peking Man. However, modern genetic research does not support this hypothesis. A recent study undertaken by Chinese geneticist Jin Li showed that there was no inter-breeding between modern human immigrants to East Asia and Homo erectus, contradicting the Peking Man hypothesis and affirming that the Chinese descended from Africans in accordance with the Recent single-origin hypothesis.^[7]^[8]^[9] However, some paleontologists see continuity in skeletal remains.^[10]
