Computer program traces ancestry using anonymous DNA samples
Date:9/20/2007

backgrounds and aid historians and anthropologists in their study of where different populations originated and how humans became such a hugely diverse, global society.

Their program was more than 99 percent accurate and correctly identified the ancestry of hundreds of individuals. This included people from genetically similar populations (such as Chinese and Japanese) and complex genetic populations like Puerto Ricans who can come from a variety of backgrounds including Native American, European, and African.

When we compared our findings to the existing datasets, only one individual was incorrectly identified and his background was almost equally close between Chinese and Japanese, Drineas said.

In addition to Drineas, the algorithm was developed by scientists from California, Puerto Rico, and Greece. The researchers involved include lead author Peristera Paschou from the Democritus University of Thrace in Greece; Elad Ziv, Esteban G. Burchard, and Shweta Choudhry from the University of California, San Francisco; William Rodriguez-Cintron from the University of Puerto Rico School of Medicine in San Juan; and Michael W. Mahoney from Yahoo! Research in California.
