The Peking man remains are very strange and it is believed that most disappeared during World War II, so scientists are very excited about the published analyzes of a 600,000 year old tooth of the ancestor of modern man.
According to Liu Wu of the Chinese Academy of Sciences, the tooth in question is an upper canine from a Pekingese man. The tooth is fully developed, indicating that belonged to an individual between the ages of 20 and 40 and shows two large nicks, one of which occurred before the individual's death, so it is possible that the teeth were used as tools or to chew on solid objects such as nuts or animal bones.
Liu has revealed that in the future the investigations that will be carried out on the tooth will be to know what residues it contains and what kind of food did the Peking man eat.
The crown and root of the tooth are smaller than those of other found teeth, which may indicate that the tooth comes from a woman, although Liu has affirmed that only by a tooth it is not possible to know the gender.
After World War II, the only surviving remains of the Peking man were three teeth that were preserved at Uppsala University and it wasn't until 2011 that the fourth was found.
In the middle of the 19th century, archaeologists began to search for evidence of our ancestors and in the 20th century they reached China. Otto Zdansky, from Uppsala University dug up the Peking man's first tooth in 1921.
It was between 1928 and 1937 that numerous remains of "Peking men" were found, including five skulls and remains of more than forty individuals, but in 1941 all these remains were lost and only the teeth could be saved and they are the only proof that Peking man existed.
