Genographic project
This morning a Dr Spencer Wells appeared on Australian breakfast
television, promoting his "Genographic" project that is sponsored by
National Geographic (see
http://www3.nationalgeographic.com/geno ... urney.html).
In the course of the interview he claimed to have discovered that 10%
of "Asian" males (strangely, he didn't specify further) are descended -
presumably in agnatic line for their sex to be especially relevant -
from Genghiz Khan. The clear implication was that if enough people buy
the test kit he was flogging & participate in his study, more such
startling information will be uncovered about other historic
individuals.
Does anyone know the background of Dr Wells, and whether his work in
this field is highly regarded by experts?

Re: Genographic project
Is it actually possible to determine this? Someone correct my false
understanding that you could be descended also from one of Genghis' brothers or
paternal uncles and still have the same Y-DNA ? Is that correct.

However, see

The names Elena Balanovska (North Eurasia),
Fabricio R. Santos (South America), and
Lluis Quintana-Murci (Central and Western Europe)
are also very well known and highly regarded.
Theodore Schurr (America) and Chris Tyler-Smith

I like Schurr, but some like him less than I. Tyler-Smith
suffers by association with Sykes.
The other names I am unfamiliar with.

How about if you would be female ?

Consider this situation. Consider the possibility that Genghis belonged to a
sub-clan who were all male-line cousins. If second-cousins always married
each other ONLY if their fathers were cousins (not their mothers), then you
would get a large group of men with the same Y-chromosome.
Now, the advantage of that sub-clan, relatives of Genghis could explain
their increased productivity in making new descendents. And yet they are not
all Genghis, but they all do share a common male ancestor. He just might be
100, 200 or 800 years prior to Genghis.

I don't know his reputation, but I don't see paying to contribute my DNA
when there are other funded projects which will send you their DNA kit
free.

On average an adult male will have one son who survives to adulthood,
or slightly more if the population is increasing. In other words, the
growth rate of an agnatic line depends only on the productivity of
those males (e.g. the *number* of wives and partners) not their *choice*
of wives. It's a well-known historic fact that Genghis' sons and grandsons
were *very* productive; what percentage of his enormous Y-chromosome
posterity descends instead from his brothers or cousins depends on when
this unusual sexual productivity began.
I note that Leo van de Pas's site shows rather few agnatic descendants
for Ghenghis, compared with say Egilmar's Oldenburgs. Most of the lines
from Ghenghis are via Juchi (who Leo shows as stepson); even there Leo
shows just one post-medieval agnatic lineage.
Summary: We're all descended from Ghenghis but will have trouble gaining
admission to the International Society of the Sons of the Golden Horde
because our descents depend on undocumented rapes.

I can't understand any sense in this at all - can you please let us know
more clearly just what preconceived notion of your own you are reading into
my words?
And kindly refrain from editing out sections of other people's posts in your
replies (as below) without indicating this. It is surely easy enough to
insert "<snip>" or something like it.

But aren't there significant "Asian" populations that would not be expected

Why would this descend to large numbers of Indians or Arabs, Burmese,
Laotians, Vietnamese, and others?
And if not, what proportion of Chinese, Turkish and other populations must
inherit the Y-DNA in order to make up 10% of the whole?
I still find it suspicious when an alleged expert claims scientific proof
that decendants of Genghis make up 10% of the entire, undifferentiated
