Yair:

The list is alive, but not very active.

R1b1b2e is the new name of R1b1c7, but the name of the list has not been
changed.

To see how R1b1b2e fits in with other haplotypes, have a look at the new
Y-Chromosome Phylogenetic Tree, which is available on the FTDNA website,
among other places. Here is a link to a pdf of the chart: *

I don't know what you mean by "anomalies in the family tree." It is what it
is.

Yes, this list is primarily focused on genetic genealogy.

Your question about "tribe" and "ethnic sub-division" has been repeatedly
and clearly answered many times. Y-DNA gives zero information about
ethnicity or tribe. For your convenience, I have pasted one of the answers
to your persistent question that I posted on this list last June:
"Close Y-DNA matches on large marker-panels do give evidence about genetic
and genealogic connections in the paternal line. That is what got most of us
on the list interested in this science. But even perfect 200-marker Y-DNA
matches do not give us information on ethnicity or appearance. Consider that
an R1b1c7 great great granddaddy of a large number of offspring by different
mothers could have been a sailor, who fathered sons in every port--one in
Norway, one in Spain, one in Africa, one in India, one in Cambodia, one in
China, one in Tonga... Now suppose each of these sons remained with their
mothers, married local women, and their descendants remained in each of
these places and interbred with their neighbors, [spoke the same language,
followed the same customs...]. Each of our R1b1c7 sailor's second great
grandsons will have received 100% of his Y-chromosome, and 6.25% (1/16) of
his other genetic material, on average. [And all would be in exactly the
same sub-clade of the same Y-haplogroup.] What would their ethnicities be?
They would be Norwegian, Spanish, African, Indian, Cambodian, Chinese, etc.
And what would they look like? Mostly, they would not look particularly like
their great great granddad--they would look like their neighbors. [And it
would be just plain silly to call all of them "Irish."]

This does not mean that it would be useless for them to check their
Y-chromosomes to find out who their 2nd great granddad and his paternal line
ancestors may have been. But it does mean that it would be useless for them
to check their Y-chromosomes to figure out what their ethnicity or "racial
characteristics" may be."

Y-DNA studies trace the strict paternal line. Period. This has nothing to do
with ethnicity. Period.

The Y-chromosome has only about 30-odd genes, almost all of which pertain to
spermatogenesis, so any significant mutation tends not to be passed on. As
far as I know, the only medical implication so far discovered is the linkage
between a specific null STR and one type of male infertility.

There are no "proclivities" of Y-DNA haplogroups. The markers that determine
haplogroups and haplotypes find NO EXPRESSION in the phenotype, they do not
code for proteins, they do not mark ethnic groups, and they do not support
crack-pot theories of the Israelites settling Britain. Give it a rest.
