    Z85 has been positive in L664 (in fact in all M417 including Z283 and Z93) so far, except for kit 170526. This was reported by FTDNA as negative, but in fact the test was inconclusive rather than negative. This was only learned recently, and the upshot is that Z85 is probably near or equivalent to M417.

    My Z85 test results appeared today on my page. I am Z85+. That has confused the experts, apparently, since we all seemed to expect me to be negative. Now the question is: a separate independent mutation? Or the tree has to be reworked a little.

    Correction: M198 is about 8,000 years old (6,000 B.C.) on Lapinski's chart.

    On the whole, I would encourage someone to order Z85.
    Thanks for your informative answer. I guess I'll go ahead with it, then.

    New SNP Z85 for R1a1

    Tell me about this new SNP Z85, and why I should do it. From 1000 Genomes, it is near M417. I am already positive for M417. How close in time is Z85 to M417? Are they synonymous, or is there a significant time difference? Since my L664+ branch is older than Z283 and Z93, this is a meaningful question. That is, L664+ split off from M417 earlier than the other two groups did.
