J1b M365 is definitely negative (ancestral) to P58.

I received my 23andMe results. Very interesting !
P58 (J1e) rs34043621 can point to an interesting position in the J1 haplogroup.
In general terms P58, J1e, was an historical edge on the J1 history and J1e P58+ is far more associated to the Semitic groups. J1 with the negative P58 is absolutely not related to the Semitic populations. Probably J1 was born around the Taurus-Zagros line and the oldest and most diversified J1 haplotypes are located in the Anatolian and Caucasian areas, where some of the highest frequencies of J1 in the world are found in places like Daghestan. J1e and the modals found in the Jewish and Arab populations to the South are considerably younger and less diversified.
I am P58- (negative, ancestral, with the TT) what points to the ancient Northern variants of J1 in the J1b clade, just like the known J1 DYS 388=13 cluster.
I am TT positive to L60 rs2008924, definitely another J SNP

A new methodology of estimating ancient or medieval "Invaders" Y DNA in Europe

The recent article “Moors and Saracens in Europe: estimating the medieval North African male legacy in southern Europe” (Capelli et al - European Journal of Human Genetics (2009), 1 – 5) proposes a methodology: “So, considering 9 loci and 40 generations (approximately 1200 years ago with a 31-year generation length14), either 0 or 1 mutational difference is the most likely consequence. Two mutations are only slightly less likely, but overlap with other much more ancient events, for example 80 generations or 2400 years ago. Posterior distributions for more ancient events have probability peaks centred on a higher number of differences, with 0–1 mutations being extremely unlikely (data not shown). Therefore, following this, European Y chromosomes within the three haplogroups identical to, or with one mutational difference from, NW African STR haplotypes were considered compatible with an MNA (medieval Northern African) ancestry. In Iberia and peninsular Italy, they account for 90, 78 and 42% of the E1b1b1b, E1b1b1a-b and J1 chromosomes respectively”.
(9 STR loci - DYS19, DYS389 I–II, DYS390, DYS391, DYS392, DSY393, and the bi-allelic DYS385)

The same methodology can be applied to the YHRD results for the “J1b modal haplotype candidates”, the presumed “Western Alan Modal haplotype”
(9 STR loci - DYS19, DYS389 I–II, DYS390, DYS391, DYS392, DSY393, and the bi-allelic DYS385)

A new haplotype found in the YHRD database. Caceres is very close to the Portuguese border and was part of the old Roman Lusitania. (Catálogo Monumental de Caceres - “ocupada por Alanos”).

We can even imagine that the Alans ride from the Caucasus to Lusitania, as an ethos or an attitude, would be resumed after some centuries and would go on over the Atlantic and would continue in the Brazilian wilderness with the Bandeirantes, century by century !
