Israeli scientists ‘track’ ancestors using DNA test

An Israeli scientist claims to have developed a way of accurately establishing where a person’s parents, grandparents and ancestors hail from by analysing their DNA.
Eran Halperin of Tel Aviv University developed a mathematical algorithm for extracting information about family origins from a DNA sequence called the single-nucleotide polymorphism. He made the breakthrough in partnership with Elazar Eskin, a computer scientist at the University of California, Los Angeles.
