Following on from my
article on blood groups came a “scientific” paper to claim that people who
are Rhesus negative are descended from Aliens. This is nonsense and very
poor application of statistics. However, DNA testing applied correctly can
turn up some startling results.
Let’s begin with some
medical facts: Bruises on a child’s body are often considered proof that a
baby has been battered. A visible bruise on the buttocks, the shape of a
hand and five fingers is almost ‘undeniable’ proof. In fact, there was a
very celebrated instance of a GP in the UK having discovered that so many of
the Asian babies in the practice were showing signs of being ‘battered’ that
the children’s welfare people were called in and an enormous number of
children taken away. However, the highly observant GP was wrong!
In Thailand, and the
rest of Asia, a new-born baby with the ‘handprint’ bruise is very common,
while child abuse is not common at all. The problem, or rather the
condition, relates back to Genghis Khan and the Mongol hordes. It is a
wonderful piece of folklore and also a fine example of applied genetics.
Let’s look at the
folklore first, and you are going to have to dig very deep to get this tale
anywhere else! A Mongolian baby, called Tanujin, was born just over 1,000
years ago, but did not breathe. His father, in desperation, held his
new-born son upside down and smacked him severely over the bottom, so much
so that the baby drew breath and lived, but carried the life giving bruise
for the rest of his days. That baby later became Genghis Khan (which means
King of the Earth), and by the time he died in 1227 he was the ruler of a
large chunk of it, including the area which later became known as Thailand.
History has chronicled
that the Mongol hordes raped, pillaged and annexed countries from China to
Persia. Famous cities were captured and looted such as Tashkent, Baghdad
(still a good place to stay away from, thanks George) and Bokhara. The
Mongols conquered northern India and Afghanistan. In 1222, they defeated the
Russian and Bulgarian armies. At the time of Genghis Khan’s death, his
empire stretched from China’s Yellow River to the Dnieper, in Russia.
And now back to some
interesting folklore. The descendants of Genghis Khan also showed the
hand-shaped bruise on the buttocks, beginning with his four sons Ogdai,
Jagatai, Juji and Tule, who were given one quarter of the empire each after
their father died. They in turn passed on this ‘trademark’ and so this
continues till today. If your “Luk Krung” children have the sign of Genghis
Khan, called Mongolian Blue Spot, you can claim descent from the warrior
king. However, there is quite a number of you, so I think there won’t be
much left in Genghis’ estate by today.
Now Mongolian Blue
Spot, as a clinical condition, is well documented, and I came across figures
suggesting that at least one Mongolian spot is present on over 90 percent of
Native Americans and people of African descent, over 80 percent of Asians,
over 70 percent of Hispanics, and just under 10 percent of fair-skinned
infants (Clinical Pediatric Dermatology, 1993). The distribution was
followed through with DNA testing.
Medically we describe
Mongolian Blue Spot as flat bluish to bluish gray skin markings that
commonly appear at birth (or shortly thereafter) and scientifically they are
called congenital dermal melanocytosis. They appear commonly at the base of
the spine, on the buttocks and back. The medical text books also warn that
occasionally Mongolian Blue Spots are mistaken for bruises and questions
about child abuse arise. Obviously a text book that the UK GP did not read!
Mongolian Blue Spots are birthmarks, not bruises.
So, for all of you with
children with a peculiar blue birthmark on their bottoms, or for those
interested in checking friends and neighbors (or the young ladies dancing in
the chrome pole palaces), it seems fairly positive that the lineage is
verified. You really have found descendants of the man who conquered more of
the world than Alexander the Great. And guess what – my children have it
