Brit-Am Impression: R1b1 is
the Y(male
-determined) DNA of many West
Europeans though it has minor offshoots elsewhere.
The opinion expressed below would trace its origins to Southwest Asia
(where the Land of Israel is situated) with finds amongst present-day Jews being
used
as indicators.

Subject: Re: [DNA] eastern R1b1c modal (was DYS 389-2)
Extract:
I believe that the difference in estimated ages for ht15 and ht35
might help us understand the LGM-era movement of R1b1c.
First let me issue the standard caveat that R1b desperately needs
(and deserves) a focused study along the lines of the studies that
have emerged on E3b, I, and J among others. Only a detailed an
extensive study can properly test the many theories on the subject.
But having said that, here's my take.
The evidence points to a southwestern Asian (and I include the
Caucasia in that group) as the point of expansion for just about
every subclade of R1b1 that I have studied. R1b1b appears to have a
southwestern Asian (SWA) origin, not a Central Asian origin as
postulated by Spencer Wells and others. Four of the six major
clusters of R1b1* that I have identified are found almost exclusively
in Jewish and/or Near Eastern populations. The origin of the other
two is uncertain - they are young and found in the UK mostly - but
I wouldn't rule a crypto-Jewish affiliation for them.
It appears that ht35 is older than ht15, by a little bit at least,
and ht35 is found at high concentrations in SWA and in Jewish
populations. Moreover, on the markers where ht15 and ht35 differ
(DYS393, DYS461, DYF385, etc.) ht35 has the same modal values as
R1b1b. In short, ht35 maintains the ancestral value and ht15 has the
derived value.
There is little doubt that ht15 expanded out of Iberian peninsula at
the end of the last ice age, but my personal theory is that it
arrived in Iberia after the LGM and before the Younger Dryas. In
other words, R1b1c expanded out of SWA at the end of the LGM only to
be forced back south during the Younger Dryas. For whatever reason,
either during the journey from SWA to Iberia or during a bottleneck
in Iberia itself, the split between ht15 and ht35 manifested.
This explanation explains the most basic facts: dual radiation
patterns from separate refugia, largely similar founder haplotypes,
and the closer similarity of the R1b1b modal to ht35 than to ht15. I
cannot think of another explanation that accounts for all the known
facts more neatly.

Brit-Am Impression: The
Abstract below appears to suggest that the
motochondrial
(female-trasmitted)
DNA of the Arabian Peninsula indicates a 62% "Northern" origin,
20% from Africa, and 18% from the east, mainly from India.
Furthermore it is implied that the 62% "Northern" markers were the oldest ones.

ABSTRACT: BACKGROUND: Two potential migratory routes followed by modern
humans to colonize Eurasia from Africa have been proposed. These are the two
natural passageways that connect both continents: the northern route through the
Sinai Peninsula and the southern route across the Bab al Mandab strait. Recent
archaeological and genetic evidence have favored a unique southern coastal
route. Under this scenario, the study of the population genetic structure of the
Arabian Peninsula, the first step out of Africa, to search for primary genetic
links between Africa and Eurasia, is crucial. The haploid and maternally
inherited mitochondrial DNA (mtDNA) molecule has been the most used genetic
marker
to identify and to relate lineages with clear geographic origins, as the
African Ls and the Eurasian M and N that have a common root with the Africans
L3.
RESULTS: To assess the role of the Arabian Peninsula in the southern route, we
genetically analyzed 553 Saudi Arabs using partial (546) and complete mtDNA (7)
sequencing, and compared the lineages obtained with those present in Africa,
the Near East, central, east and southeast Asia and Australasia. The results
showed that the Arabian Peninsula has received substantial gene flow from
Africa (20%), detected by the presence of L, M1 and U6 lineages; that an 18% of
the
Arabian Peninsula lineages have a clear eastern provenance, mainly
represented by U lineages; but also by Indian M lineages and rare M links with
Central
Asia, Indonesia and even Australia. However, the bulk (62%) of the Arabian
lineages has a Northern source. CONCLUSIONS: Although there is evidence of
Neolithic and more recent expansions in the Arabian Peninsula, mainly detected
by
(preHV)1 and J1b lineages, the lack of primitive autochthonous M and N
sequences,
suggests that this area has been more a receptor of human migrations,
including historic ones, from Africa, India, Indonesia and even Australia, than
a
demographic expansion center along the proposed southern coastal route.

Shalom, my name is W, I would like some information on how or whom I should contact as to my Hebrew family tree. I have been a christian all my life, and have always known the hebrew roots to our faith but the last three years my wife and I have studied this much closer. I'm finding the ALMIGHTY is impressing on me to search my family tree way back. I'm not sure why? If you guys can point me in the right direction or person to help me research this matter it would muchly appreciate thanx. C.
