Otzi
the Iceman was found in the Italian Alps in 1991. It has been reported that scientists
have found 19 genetic relatives of Otzi living in Austria’s Tyrol region.
Walther Parson, a researcher for the Institute for Forensic Medicine, states “These
men and the ‘Iceman’ had the same ancestors. These 19 genetic matches were
discovered using the DNA records of 3,700 Austrian blood donors for a rare
Y-chromosome mutation known as G-L91. This mutation is passed down intact from
one generation to another and is a very dependable indicator for ancestral
relationships. Unfortunately, since this mutation is on the Y sex chromosome,
it can only be traced to male ancestry.
Scientists
are using these genetic markers to obtain better knowledge of how the different
populations migrated throughout the Alpine regions. Through this study, APA
scientists expect to find relatives in other nearby regions of the Swiss and
Italian Alps. Scientists have learned a lot from the frozen mummy. It is
assumed that Otzi was a farmer that suffered heart disease, joint pain, tooth
decay, lactose intolerance, and most likely Lyme disease. Even though they have
revealed that they have found 19 genetic they have not released names and it is
certain that these relatives do not know that they are related to Otzi.

I found
this article to be very interesting. Otzi had been preserved for thousands of
years and remains intact and still gives us information on how people lived
then and how his DNA still exists in the world today. I find it amazing that
they can take the DNA of a 5,300 year old ‘Iceman’ and see where his ancestry has spread
throughout the world. I hope that they do more investigation into people that
would be related to Otzi and see how far his genes have spread around the
world. Also, they should get inform the ancestors who they are so they can get
more family history for them. It is a bit of a disappointment to me that they
can only find the gene in the Y sex chromosome, but any amount of information
is still supportive and historical.

I thought this article was very interesting. I have never heard about the Iceman before and I find it pretty amazing that they can determine all of that information about him just by looking at his corpse. It amazes me that he is so well preserved and that scientists continue to find even more people that are or could be related to the Iceman.
ReplyDeleteThis remarkable DNA discovery of a rare mutation known as G-L91 in Ötzi’s mummified body has identified at least 19 common ancestors on his paternal side. It is interesting that the descents have not been notified. This discovery has revealed a rather remarkable portrait of the Iceman and its genetic groups and subgroups. This breakthrough will additionally enable scientists to better understand early human migration.
