with the means to verify the number of historical mysteries
Fudan already established by the common history of genetics and the history of anthropology in the new discipline, hope and historical literature of modern biotechnology research collaboration will focus on integration of the Chinese nation's history, the context of evolution a study, future research can not be expected to reveal the answers to the more traditional historical mystery.

group experts said that one hundred percent of historical research is often difficult to draw the right conclusions. Under the existing number of chain of evidence, through human statistics, forensic science and other research methods generally accepted comprehensive analysis, the possibility should be above 90%.
present, on the basis of this research, Fudan University, has begun to form by the genetics and history to participate in the new discipline of anthropology, history, hope, and historical documents of modern biotechnology research collaboration, focusing on will be for the history of the integration, evolution and development of a study context, is also expected to reveal more traditional research can not answer historical mystery.
Hanjie Shao, Cao Cao family of DNA in this study, and not just also verified the same way the prime minister Han Cao family genes, genes with Cao Cao's family does not matter, so that descendants of Cao Cao Cao is the argument could be forged; Secondly, there is the legendary name is Cao Cao speaking descendants of a refuge from a change of surname after gene validation between the two surnames is no clear genetic relationship; In addition, studies have shown that existing gene Jaap's family genes is also inconsistent with Cao Cao,[url=http://www.coachbagsu.com/]Coach Online Outlet[/url], Cao Cao therefore adopt a child from Jaap's argument is likely to be descendants of the slander.
these studies validate each other, indicating that these six groups Cao Cao is the most likely descendants.
more credible chain of evidence over 90%
are long long time ago. percent. accurate detection of sequence, it is precisely their common ancestor about 1800 years ago. From the genealogy point of view, they were from Cao Pi,[url=http://www.coachbagsu.com/]Coach Online Outlet[/url], Cao Zhi different offshoot, but offshoot of the same family tree on genetically more similar. If you want to exclude that they are descendants of Cao Cao, leaving a situation: the ancestors of 1800 years ago, fake Cao Cao, but also let their children were to pretend to Cao Cao's sons, this 1800 should continue as posing years, the probability is very low.
for the widespread concern about the ability to verify the DNA technology remains Anyang tomb of Cao Cao, Li explained that the technical level, as long as preserved, the sample should be within 5 years can be detected, but For various reasons, there is no consensus and the parties concerned, but they welcome the remains of detection.
then these eight groups of Cao than the discovery of DNA samples, including six families of genes belonging to O2-M268 type, not between the other two common genes. Finally, Fudan Key Lab of these Y-chromosome DNA samples of the fine of 500 million sequence detection, the final proof: this six O2-M268 type of intersection of the ancestors of the sample in 1800 and 2000 years ago.

This means that a person's name can be an important marker of biological genetics, a family name in the inheritance of men pass mark on the Y chromosome.
last name contains the human one pair of sex chromosomes, the female sex chromosome composition XX, males are XY. A couple born son, the father of DNA on the Y chromosome will spread to his son on the Y chromosome, but not to daughter. If the parent had children, child health Sun, Sun gave birth to great-grandchildren, passed along this way, Y chromosome is always accompanied by the transfer. In the absence of mutations under the premise that each man and his ancestors have the same one Y chromosome.
2009, the Cao family, Fudan University to carry out DNA research, and surnamed Cao in the national collection of DNA samples, looking for the descendants of Cao Cao. Throughout the study is divided into two lines of biological and historical, and cross-checked: first by the extensive collection of contemporary genetic laboratory Cao male genetic samples, draw a genetic map, surnamed Cao, ran in the end to see from the number of ancestors. Followed by historians through a variety of data collection, analysis, future generations may find clues to Cao Cao. In this process, surnamed Cao, ran the first of hundreds of genealogy made a comprehensive study of the comb, and the same history books, local history and other historical data were compared to see if there even a little clue to obtain access to it, such as various Cao ancestors and now live and historical records on the flow of Cao Cao's offspring can not match and so on, thus filtered out of the eight support genealogy, through historical analysis has a certain credibility Cao groups.
reporter learned that, if the DNA prior to the international research results, can only identify a modern or ancient samples belong to a racial and ethnic, this Cao DNA research, is the world's the first time accurate to the ancient family of genetic research, it benefits from China's social stability and tradition, including surname genealogy information, including the rich culture, is also expected to let the historical development of human reproduction and the evolution of human genes have a law new breakthroughs in understanding, which should be better than to find descendants of Cao Cao who is more meaningful.
find the six most likely descendants of Cao Cao
microblogging Recommended | today's hot microbloggingShucheng County in Anhui Province, a small village, the village most people have the surname Cao, their number is called the instrument the family court One Church. One day last summer, the arrival of Fudan University research group, to the surprise of this big family. After sampling verification, they Shucheng another really Cao family court with a seven-step gene - O2-M268 model, and in Liaoning, Anhui, Hunan, Jiangsu, have blood on their relatives. They are the descendants of Cao Cao's it?
Evening News reporter Zhang Cc report
Cao Cao in the end there are no descendants? History professor at Fudan University, China Wei, vice president of Korean History, said Sima Yi in the process of political transition, the descendants of Cao did not conduct any of the massacre. among the Cao family, although these six genes have the same type, but what said this six Cao Cao offspring population is it? The credibility of this study how much?
from 2009, Fudan University to carry out DNA analysis on Cao Cao's family,[url=http://www.coachbagsu.com/]Coach Online Outlet[/url], surnamed Cao in the national collection of DNA samples. This morning, Fudan University, published research, the school's biology and history experts together to complete, surnamed Cao, ran through the crowd of modern DNA analysis, and historical records, gazetteers, genealogy and other historical materials of multiple reflection, in order to identify six Cao s population is most likely descendants of Cao Cao. The study, the first time in the world, accurate to the ancient family of genetic research. Recently, the relevant papers in internationally renowned academic journal
