there is intense interest in the origins and histories of people. By utilizing the genetic record that each individual
retains of his or her past, it is possible through molecular biology to reveal important clues as to
the origin and relationship of any individual to other persons or
populations. Dr. Scott
Woodward and his research group at Brigham Young University in Provo, Utah, are
among the pioneers in this new research field. The Molecular
Genealogy Research Group, under his direction, is using the genetic
information contained in human DNA to reconstruct worldwide family trees.
All persons
receive genetic material from their biological parents. This fundamental
principle of genetic transmission means it is possible to determine the
origin of genes based on common ancestry and known modes of inheritance.
Because this process is repeated every generation all individuals carry
within their DNA a record of who they are and how they are related to
all of the other people on the earth.
By
applying the principles and techniques of molecular biology to the question human origins
and genealogy geneticists can links individuals together in
"family trees" based on the unique identification of genetic
markers. Scientists accomplish this by using the information encoded in the
DNA, particularly mitochondrial DNA (mtDNA), of an individual and/or population to determine the relatedness of
individuals, families, tribal groups, and populations.
Moreover, different regions of
DNA have the ability to identify individuals, link them to immediate
family groups, extended family, tribal or clan affiliations and larger
populations. Pedigrees based
on genetic markers can reveal relationships not detectable in
genealogies based only on names, written records, or oral traditions. In order to reconstruct molecular genealogies it is
necessary to utilize known biological relationships and correlate this
information with the transmission of genetic markers through time. As
individuals trace their biological relationships into the past, lineages begin to "coalesce" into common ancestors.
Since one of the goals of this research is to establish genotypic links in each population and
between each of the populations it will be possible to
establish ancient immigration and migration patterns. Individual
families will be linked to their ancestral homelands and the
contemporary populations that share a common genetic heritage. This
should furnish a definitive explanation of the fate of the Ten Lost Tribes
of Israel and provide researchers new insights into the archaeology and
history of the Bible lands.
The Molecular Genealogy Research Group seeks to build a
database containing over 100,000 DNA samples from individuals all over the
world. Each participant will complete a biological pedigree chart of at least four
generations and provide a small blood sample. Once the database has sufficient samples to
represent the world's genetic make-up, it will eventually help in solving many
issues regarding genealogies, peoples, population movements, and tribal
identities, that could not be done by relying only on
traditional written records. In theory, anyone will someday be
able to trace his or her family origins through this database.
The Molecular Genealogy Research Group would like to
hear from people with
known genealogies that would be willing to participate in this study and help in
building the database. Being 18 and older and having at least a four-generation
pedigree chart are the two qualifications necessary to participate in the
study.
