Use of DNA to pinpoint tribal heritage disputed
Thursday, October 19, 2006
Genetic tests that claim to pinpoint a person's tribal identity may not be accurate, according to a recent British study.
Based on the DNA of African-Americans, researchers found that fewer than 10 percent could be traced to an actual tribe or ethnic group in Africa. A much larger number, 40 percent, couldn't be matched at all, according to the study.
At best, researchers say the DNA tests can point to a certain region in Africa.
