The men in yellow are going to be SNP tested. They share a rare STR allele with the aforementioned group (DYS392 = 12) and might be more closely related to each other than to others, but it's not conclusive based on their 37 STRs.
Note the proximity of these confirmed/predicted basal J2b-L283 lineages to our oldest J2b-L283 sample found in Europe, MOK15 from Mokrin, Serbia. This ancient sample is not basal J2b-L283 like the men in red circles are, but is J2b-Z615*, which is the major child lineage of J2b-Z600 from which most living J2b-Z600 (and J2b-L283 for that matter) descend.
So these men could be the previously until now missing pieces of the puzzle indicating how our ancestors migrated to Europe in the Bronze Age*.
(* Note that it's actually possible our ancestors were in Europe since the Neolithic but it's not the favored theory because none have been found there before the Bronze Age and we do have some ancient, apparently basal J-L283 from the Caucasus - KDC001 in Kabardino-Balkaria and RISE408 from Norabak near Lake Sevan, though they not as old as the Mokrin samples)
PhyloGeographer is going to be using YFull dates for ancient samples from now on, because I can automatically get the data from them and I trust they will get it right.
I would like to upgrade these men and other previously identified men in J2b-YP91 to a WGS test to advance the research into our common origins.
