All four groups share a common ancestor down to R1b1b2a* (M269, 18,500 years ago). Group three continues to be on the original course at R1b1b2a*. Group one branches off at (L-48, 3,300 years ago) and becomes R1b1b2a1a4. Groups two and four branch off together at (U152) but then Group 2 continues on this path R1b1b2a1b4 as group four makes another branch at (L20) and becomes R1b1bb2a1b4c1. The * indicates that the final SNP has not yet been found at time of testing (yet to be discovered). Members should print out the charts (right click on large photo and select print picture).
