DNA (Deoxyriboncleic Acid)
DNA has the ability to connect branches of the family,
often separated by both geographical and chronological distance. DNA testing
can provide invaluable, and often surprising, information about your
origins if the paper trail runs cold.
Recent advances in scientific knowledge have produced sophisticated
analytical techniques surrounding DNA, whereby samples can be
traced to specific individuals. There are various DNA tests for
example ancient maternal ancestry by testing mitochondrial DNA (mtDNA)
and a Y-chromosome DNA test. An Oxford University geneticist Bryan Sykes
published research showing that everyone of
European extraction could trace their ancestry back to one of seven
women the "seven daughters of Eve" who lived 40,000 years ago.
