Ancient DNA May Be Misleading Scientists

Ancient DNA may be misleading scientists

Tuesday, 18 February 2003

Dating skeletal material with DNA may not be as acurate as thought

Ancient DNA in skeletons has a tendency to show damage in a particular region, resulting in misleading genetic data and mistaken conclusions about the origin of the skeleton, British scientists said.

A group of researchers at the Henry Wellcome Ancient Biomolecules Centre of the University of Oxford, in Britain, made the finding while studying Viking specimens. They found that about half of the specimens had DNA that suggested they were of Middle Eastern origin.

But more detailed analysis revealed that many of the genetic sequences in the double helix molecule, which carries the genetic information of every individual, were damaged at a key base that separates European sequences from Middle Eastern genetic types - damage which made the skeletons appear to have originated in the Levant.

The results are published in the February 2003 issue of the American Journal of Human Genetics.

Damage events appear to be concentrated in specific 'hotspots', indicating that a high proportion of DNA molecules can be modified at the same point. These hotspots appear to be in positions that also differ between different human groups. In other words, the DNA damage discovered affects the same genetic positions as evolutionary change.

"Now that this phenomenon has been recognised, it is possible to survey the ancient sequences for damage more accurately, and determine the correct original genetic type - open the way for more reliable future studies," said Professor Alan Cooper, director of the centre.

Cooper has hopes the finding may have implications for future research. "It also appears that we can use damage cause after death to examine how DNA damage occurs during life - a completely unanticipated, and somewhat ironic result," he said. "Potentially this allows us to get uniquely separate views of the two major evolutionary processes, mutation and selection."

The 'Middle Eastern' link is still showing up in the DNA data in the most recent books I've read relating to Vikings, etc.

"Oops...there goes another theory."

Maybe.

It may affect the theory that 'Middle Easterners' brought farming to Europe. As of late, the 'farmers' DNA in Europe is turning out to be very sparse anyway.

Thanks Blam. I think this is a recycled story from last year by some lazy journalist. :') But I'm sure we'd all forgotten these details.

Nope. I posted an old article.(Notice the publishers date, 2-2003) I hadn't seen it before and it was pertinent to the last couple of new books (using DNA data) that I read.

So what’s the problem? The vikings (Danes) were decendants of the lost tribe of Dan, one of the lost tribes of Israel.
If I remember right, Israel is in the Middle East.

OK so here's a wild idea brought up by my buddy who is of Viking genealogy.

Did Dan Brown get it wrong and the descendent's of Jesus went to Scandinavia not Southern France? :-)

DNA Heritage

18,000 Years Ago

12,000 Year Ago

The running argument today is whether the DNA haplogroup 'I' or R1a are the 'TRUE' Vikings.

My present opinion is that the 'Vikings' are mainly R1a but may be a combination of R1a and 'I'. My YDNA is R1b and my dad had two sisters with red-hair (which they dyed black their whole lives).

BTW, 90% of the Irish are R1b.
My mother was haplogroup 'V' (Sa'ami - Laplander) who followed the reindeer herds, at the edge of the glaciers, north as they receded at the end of the Ice Age (They were in the north before the Vikings arrived).

The 'V' DNA ladies left the Franco-Iberian refuge with the R1b men but swapped them for 'I' men before arriving in present day Lapland.

The YDNA 'I' are the Saxons who 'invaded' the British Isles in the 4th century AD or earlier.

Very interesting info. The travels of the Vikings and their conquests are a corner of history overlooked by many. Sorry your relatives changed their hair color. Nothing like a Viking woman with red hair!!!!
