http://www.xasa.es/grupos/soc/thread...e.japan/51/100The haplotypes of Manchuria are intermediate between koreans and
northern chinese, being more like northern Han than koreans.
I expect there was some significant amount of migration of the
Jurchen with the Great Wall was extended to the north east. The
morphology and genetics of shandong changed markedly and some korean
and japanese markers could [Should] be from this region also.
-> this indicates that han pushed indiginous people in shandong to northward
The diversity of B46 haps is higher in manchuria than korea.
Koreans can be compared with Japanese, some of the haplotypes in
Koreans are missing in Japanese. These particular haplotypes are
found extensively amoung the Khalkha of mongolia, and much of the
history prior to the mongolian invasion has been lost. about 5 to 10%
are either from mongolia or manchuria and are of recent origin.
Two proximal groups, other than the Japanese have extensive
similarity with the koreans. The Orochon and the Ainu and presumbably
with more typing the indigeonous peoples of the Amur region. This
probably extended along the eastern coast into korea, however the
dynastic expansion of the han had diluted extensively the enterior of
the country. My expectation is that prior to 2800 years ago there was
no B46 in manchuria, in fact, one would be hard pressed to find it in
northern china except in the wet rice farming cultures. It also
probably did not exist on the Shandong.
Therefore in considering what is Korea today, represented by unique
haplotypes shared only between japanese(72%) and koreans one would
probably predict that this people extended into manchuria and along
the eastern coast to the amur region, and they were later compressed
by polical events that occurred to their west.
When one looks at haplotypes from asia one sees a gradient between
all the peoples from northern china to thailand to taiwan (except
aboriginals) and to parts of indonesia. Manchuria is marginally
transitional between mongols, northern han and koreans, but the
gradient steeps in slope sharply as one moved into Amur river region,
korea, mongolia and western china. Particular examples of other
compressions are in the mongolians. The haplotypes most unique to the
mongolians are not found in Native Americans, where as those in
Japanese and Ainu and other Eastern Siberians are. These unique
haplotypes are found to be similar to non-Han peoples to the south
and in Tibet.
