S127 and S116 are new additions to the R1b subclade classification table (May 2008). Prior to their discovery, all individuals who are currently S127 and S116 positive were previously known only as M269 positive (R1b1b2).
Please note that SNPs that are downstream of S116, namely M37, M65, M153, M167, M222, P66, and S28 are much older and were discovered prior to the recent discovery of S116. Their years of discovery range from 1999 to 2006. S116 is upstream of these SNPs, but it was only recently discovered and added to the tree.
Individuals who are S116 positive but negative for all of the downstream SNPs are known as S116+ (R1b1b2a2*). Please note that since S116 is very new, very little is known about S116 (R1b1b2a2*) and no distribution data has yet been published for this new marker. As new data for S116 (R1b1b2a2*) becomes available, the R tutorial will be updated. Individuals who are R1b1b2a2* S116 were previously known as M269+ so they can refer to data on M269 (R1b1b2) for further information on their subclade (ie R1b1b2 previously included individuals from R1b1b2a2*)
