How can DNA trace large numbers of people?
DNA technology is often used in disaster situations when many individual bodies need identifying. The Fromelles Project in northern France is using DNA analysis to help trace First World War soldiers who died at the Fromelles battlefield. Scientists are hoping to match records of lost soldiers to human remains from the site. The project collects DNA and other information from potential relatives who believe their ancestors fought at Fromelles. It also involves forensic archaeology, genealogy and anthropology. DNA analysis was also used to identify bodies at the World Trade Center after 9/11.
