Don’t call him 'Adam': South Carolina man’s genes help date first man
http://www.foxnews.com/science/2013/03/06/adam-gene-chromosome-help-date-first-man/DNA from an unnamed African-American from South Carolina is so distinctive that it led scientists to a unique conclusion: The roots of the human tree date back much further than previously thought.
“[His] lineage didn't fit anywhere on the existing Y chromosome tree, even though the tree had been constructed based on perhaps a half-million individuals or more. Nobody expected to find anything like this," Hammer said.
Interesting.
