Peking Man
Peking Man (now sometimes called Beijing Man), also called Sinanthropus pekinensis (currently Homo erectus pekinensis), is an example of Homo erectus. The remains were first discovered in 1923-27 during excavations at Zhoukoudian (Choukoutien) near Beijing (Peking), China. The finds have been dated from roughly 250,000-400,000 years ago in the Pleistocene.

# Original fossils
First studies began at Zhoukoudian in 1923 with an investigation of a number of caves in the limestone there. Otto Zdansky was working for geologist Johan Gunnar Andersson who described this event in Children of the Yellow Earth. According to Andersson, a local man led him, American paleontologist Walter Granger and Zdansky to what is today known as the Dragon Bone Hill, a place full of fossilized bones. The party immediately began an excavation. After Andersson and Granger left the site three days later, Zdansky found fossil teeth that resembled human molars. He did not, however, disclose his finds to Andersson and Granger. In 1926, he took them to the Peking Union Medical College, in Peking, where Canadian anatomist Davidson Black analyzed them. He later published his finds in the journal Nature.
The first specimens of Homo erectus had been found in Java in 1891 by Eugene Dubois, with the Java Man initially being named Pithecanthropus erectus but later transferred to the genus Homo.
The Rockefeller Foundation agreed to fund the work at Zhoukoudian. By 1929, Chinese archaeologists Yang Zhongjian and Pei Wenzhong, and later Jia Lanpo, had taken over the excavation. Over the next seven years, they uncovered fossils of more than 40 specimens including 6 nearly complete skullcaps. Pierre Teilhard de Chardin and Franz Weidenreich were also involved.
Excavation ended in July 1937 when the Japanese occupied Beijing. Fossils of the Peking Man were placed in the safe at the Cenozoic 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 who 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.

# 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.

# Paleontological conclusions
Because all the pre-war findings at Zhoukoudian were lost during transit to the USA, subsequent researchers have had to rely on casts and existing writings from the original discoverers.
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.
This interpretation was challenged in 1985 by Lewis Binford, who claimed that the Peking Man was a scavenger, not a hunter. The 1998 team of Steve Weiner of the Weizmann Institute of Science concluded that they had not found evidence that the Peking Man had used fire.

# 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.  
However, some paleontologists see continuity in skeletal remains.
