there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a break-through for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place.

The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database.

In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. "For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome (染色体)," explains George Green, a member of the BYU Molecular Genealogy research team.

People in a large area may possess the same DNA thread because______.

A．DNA is characteristic of a region

B．they are beyond doubt of common ancestry

C．DNA strand has the ability to identify individuals

D．their unique identification can be provided via DNA

We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population.

Pedigrees(家谱) based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records.

Why this sort of entrepreneurial extravagance is not a bad thing at all？

A.These vast and risky investments can be seen as essentially a way of recycling the enormous funds that successful firms and individuals have accumulated from you, the customer.

C.The entrepreneurial extravagance can bring people many benefits, which leads a more competitive market and higher work initiative.

D.The extravagance promotes technology to move quickly, and during the process people increase their ability to innovate, which is a virtuous circle.
