The title of this post is very misleading. The actual article is here:
http://www.biomedcentral.com/1741-7007/5/13
And the thrust of the article is that the study shows MULTIPLE mtDNS matches from African Americans to African ethnic groups. Where the poster says “no single” that doesn’t mean no matches...it means multiple matches.
Also, this article is 2 years old. Why bump a non-controversial article about mtDNA now?
