Unit 1 Tales of the unexplained DNA to unlock tomb mystery 河南考古学家说在安阳发现了曹操墓。复旦大学的专家试图作DNA比对以确定真伪。 The photo shows an unearthed tomb in Anyang，Henan Province.The local government believes it belongs to Cao Cao(AD 155 to 220)，an ancient politician. DNA tests may be able to make sure if the newly discovered tomb in central China's Henan Province housed the remains of Cao Cao，a politician and general from the Three Kingdoms Period (AD 220－280)．Scientists will take samples of DNA from the tomb and from Cao Cao's descendants to solve the mystery. The discovery of a big tomb on Dec.27，2009，which local archeologists said belongs to Cao，had brought about a debate among Chinese citizens over the evidence dug from the ancient tomb，buried in a remote village of Henan Province. Archeologists have successfully located three places where Cao's descendants might live today. Experts with Fudan University are trying to get DNA from Cao's descendants and compare it with the DNA from the bones uncovered in the tomb.“Instead of waiting for volunteers to provide their DNA samples，we decided to collect by visiting those areas that are shown by the archeologists，” Li said.
