Still Waters Posted March 4, 2013 #1 Share Posted March 4, 2013 University of Arizona geneticists have discovered the oldest known genetic branch of the human Y chromosome – the hereditary factor determining male sex. The new divergent lineage, which was found in an individual who submitted his DNA to Family Tree DNA, a company specializing in DNA analysis to trace family roots, branched from the Y chromosome tree before the first appearance of anatomically modern humans in the fossil record. http://phys.org/news...ly-thought.html 1 Link to comment Share on other sites More sharing options...
stevemagegod Posted March 4, 2013 #2 Share Posted March 4, 2013 Interesting, i submitted my DNA to the Genographic Project and found out that i belong to the Haplogroup M172 through my Y Chromosome. Link to comment Share on other sites More sharing options...
Insanity Posted March 8, 2013 #3 Share Posted March 8, 2013 (edited) Albert Perry carried a secret in his DNA: a Y chromosome so distinctive that it reveals new information about the origin of our species. It shows that the last common male ancestor down the paternal line of our species is over twice as old as we thought. One possible explanation is that hundreds of thousands of years ago, modern and archaic humans in central Africa interbred, adding to known examples of interbreeding – with Neanderthals in the Middle East, and with the enigmatic Denisovans somewhere in southeast Asia. http://www.newscientist.com/article/dn23240-the-father-of-all-men-is-340000-years-old.html Edited March 16, 2013 by Still Waters Fixed broken source link 3 Link to comment Share on other sites More sharing options...

Big Bad Voodoo Posted March 16, 2013 #6 Share Posted March 16, 2013 http://www.newscientist.com/article/dn23240-the-father-of-all-men-is-340000-years-old.html Albert Perry carried a secret in his DNA: a Y chromosome so distinctive that it reveals new information about the origin of our species. It shows that the last common male ancestor down the paternal line of our species is over twice as old as we thought. Perry, recently deceased, was an African-American who lived in South Carolina. A few years ago, one of his female relatives submitted a sample of his DNA to a company called Family Tree DNA for genealogical analysis....When Family Tree DNA's technicians tried to place Perry on the Y-chromosome family tree, they just couldn't. His Y chromosome was like no other so far analysed. One possibility is that Perry's Y chromosome may have been inherited from an archaic human population that has since gone extinct. If that's the case, then some time within the last 195,000 years, anatomically modern humans interbred with an ancient African human. 1 Link to comment Share on other sites More sharing options...
