Davidson Black, FRS (July 25, 1884 in Toronto – March 15, 1934 in Beijing) was a Canadian paleoanthropologist, best known for his naming of Sinanthropus pekinensis (now Homo erectus pekinensis). He was Chairman of the Geological Survey of China and a Fellow of the Royal Society. He was known as 步達生 (pinyin: Bù Dáshēng) in China.

Early years

Black was born in 1884, in Toronto, Ontario, Canada. When he was a child, he would spend many summers near or on the Kawartha lakes. As a teenager, he would carry heavy loads of supplies for the Hudson's Bay Company. He also enjoyed collecting fossils along the banks of the Don River. He also became friends with First Nations people, and learned one First Nations language. Black also searched unsuccessfully for gold along the Kawartha lakes.

In 1906, Black gained a degree in medical science from the University of Toronto. He continued in school studying comparative anatomy, and in 1909 became an anatomy instructor. In 1914 he spent half a year working under neuroanatomist Grafton Elliot Smith, in Manchester, England. Smith was studying Piltdown Man during this time. This began an interest in human evolution.

1917 he joined Royal Canadian Army Medical Corps, where he treated injured returning Canadian soldiers.

Later years

In 1919 after his discharge from the Canadian Army Medical Corps, he went to China to work at Peking Union Medical College. Starting as Professor of Neurology and Embryology, he would be promoted to head of the anatomy department in 1924. He planned to search for human fossils in 1926, though the College encouraged him to concentrate on teaching. During this period Johan Gunnar Andersson, who had done excavations near Dragon Bone Hill (Zhoukoudian) in 1921, learned in Sweden of Black's fossils examination. He gave Black two human-similar molars to examine. The following year, with a grant from the Rockefeller Foundation, Black began his search around Zhoukoudian. During this time, though military unrest involving the National Revolutionary Army caused many western Scientists left China, Davidson Black and his family stayed.

Black then launched a large scale investigation at the site. He was appointed primary coordinator. As such, he appointed both Caucasian and Chinese scientists. In summer 1926, two molars were discovered by Otto Zdansky, who headed the excavations and who described them in 1927 (Bulletin of the Geolocical Survey, China) as fossils of genus Homo. Black thought they belonged to a new human species and named them Sinanthropus pekinensis. He carried this tooth in a small copper case lined with velvet attached to his belt.

Later, he presented the tooth to the Rockefeller Foundation, which wanted more specimens before further grants would be given.

During November 1928, a lower jaw and several teeth and skull fragments were discovered. His find expanded the knowledge of human evolution. Black presented this to the Foundation, which granted him $80,000. This grant continued the investigation and Black established the Cenozoic Research Laboratory with it.

Later another excavator found a skull. More specimens were found. Black would frequently examine these late into the night.

Most of the original bones were lost in the process of shipping them out of China for safe-keeping during the beginning of World War II. The Japanese gained control of the Peking Union Medical Center during the war, where the laboratory containing all the fossils was ransacked and all the remaining specimens were confiscated. To this day, the fossils have not been found and no one is sure if they were stolen or legitimately lost. Only the plaster imprints were left, one at the PUMC, one at the Smithsonian in Washington, and one in London England.

In 1931 Black was awarded the Daniel Giraud Elliot Medal from the National Academy of Sciences. He died of heart failure in 1934.

Asia hypothesis

Paleotontologists who believed mans origins to be found in Asia included Johan Gunnar Andersson, Otto Zdansky and Walter W. Granger. All three of these scientists were known for visiting China and for their work and discoveries by excavating the sites at Zhoukoudian that yielded the Peking man (Homo erectus pekinensis). Further funding for the excavations was carried out by Davidson Black, a key proponent of the Asia hypothesis. Because of the finds in Zhoukoudian, such as Peking man, the focus of paleoanthropological research moved entirely to Asia, up until 1930.

Black wrote a paper in 1925 titled Asia and the dispersal of primates which claimed that the origins of man were to be found in Tibet, British India, the Yung-Ling and the Tarim Basin of China. His last paper, published in 1934, argued for human origins in an Eastern Asian context.

Trivia

• He married his wife, Adena Nevitt, in 1913, who accompanied him on his trips. They had two children together, a son (b. 1921) Davidson and a daughter (b. 1925) Nevitt Davidson. Both were born in Beijing.

• Unlike many Caucasians of his era, Davidson Black respected his Chinese coworkers. In return, he was well liked by many of them, who put flowers on his grave after his death.

• Black believed artifacts discovered in China should be kept there.

• Gigantopithecus blacki was named in his honour.

• Author Dora Ridout Hood wrote a biography on him, called Davidson Black : a biography, which was printed by the University of Toronto Press.
• G.E. Smith, the Neuroanatomist he worked under, wrote his obituary.

• Davidson Black showed an interest in Biology at an early age, despite being born to a family association with law.

Quote

• "The Peking man was a thinking being, standing erect, dating to the beginning of the Ice Age."
