Professors must justify DNA study

Professors at Fudan University in Shanghai spent a great deal of time and money using DNA technology to discover the family of Cao Cao, a legendary warlord who lived nearly 2,000 years ago. People want to know why, says an article from Chongqing Morning Post. Excerpts:

The study of a family's DNA is widely used to analyze the existence of hereditary diseases, so as to better carry out diagnosis and treatment. But as to the mystery of Cao Cao's family, it is no more than an interesting topic for a conversation over dinner.

Judging from the media coverage, the cost of this research was huge. A DNA test for liver diseases costs at least 200 yuan ($33); and a DNA paternity test costs at least 1,000 yuan. It's estimated that the collection and analysis of more than 1,000 samples of DNA used for the research cost millions of yuan. Moreover, the four years of research have consumed large amounts of resources, such as the use of labs, equipment, and human resources.

The professors from Fudan have gone all out to apply the most advanced DNA technology to solve the mystery of a historical figure. They should now devote their attention to justify why they spent so much time and money on it.
