Error found in study of African genome, researchers say

Sigma Xi SmartBrief | Feb 08, 2016

An error has been found in a study published last year on the genome of a man who lived in Ethiopia 4,500 or so years ago. The DNA study suggested that a backflow migration about 3,000 years ago resulted in shared DNA with Europeans and Asians, but researchers say they failed to make a software adjustment that led them to inadvertently overlook sections of the genome. "It was clear human error. It's just something that should have been done that didn't get done," said Andrea Manica, an author of the original study.
