Study of Ancient Farmers DNA Challenges European Origins
Thursday, November 10, 2005
WASHINGTON — A study of DNA from ancient farmers in Europe shows sharp differences from that of modern Europeans — results that are likely to add fuel to the debate over European origins.
Researchers led by Wolfgang Haak of Johannes Gutenberg University in Mainz, Germany, argue that their finding supports the belief that modern residents of central Europe descended from Stone Age hunter-gatherers who were present 40,000 years ago, and not the early farmers who arrived thousands of years later.
But other anthropologists questioned that conclusion, arguing that the available information isn't sufficient to support it.
Haak's team used DNA from 24 skeletons of farmers from about 7,500 years ago, collected in Germany, Austria and Hungary. Six of the skeletons — 25 percent — belonged to the "N1a" human lineage, according to genetic signatures in their mitochondrial DNA, which is inherited from the mother.
The N1a marker is extremely rare in modern Europeans, appearing in just 0.2 percent.
"This was a surprise. I expected the distribution of mitochondrial DNA in these early farmers to be more similar to the distribution we have today in Europe," co-author Joachim Burger, also from Johannes Gutenberg University, said in a statement.
"Our paper suggests that there is a good possibility that the contribution of early farmers could be close to zero," added co-author Peter Forster from the University of Cambridge in England.
Absence of the marker in modern people indicates they are descended from ancient hunter-gatherers rather than the later-arriving farmers, the researchers said.
But others challenged that conclusion.

Additional DNA testing has confirmed that the 'farmers' from the Middle East had a minimum affect on the DNA of the Europeans...especially in the British Isles. 85% of the DNA of the British Isles is the same as the ancient (12,000 YA) hunter-gatherers from the Franco-Iberian Ice Age refuge.
So how did those languages spread? Cavalli-Sforza is now refuted? Wassup?
Farming spreads but farmers don’t. Makes sense to me.
18,000 Year Ago
12,000 Years Ago
8,000 Year Ago
Perhaps they migrated to Europe from Mexico.
Looks like our Rb1 ancestors ate their crops and then kicked them out (or worse).
What is N1a? is that ‘Nasreen’ (according to Oppenheimer’s nicknames)?
Every nation is a nation of immigrants.
Martin, that graphic isn’t the least bit humorous. :-)
I think so. I get so confused...everyone of these guys make up their own names and numbers, confusing.
"In their migration to India, African people carried the mitochondrial DNA strain L3 and Y chromosome line M168 across south Red Sea across the southern part of the Arabian Peninsula. On the maternal side the mtDNA strain L3 split into two daughters which Oppenheimer labels Nasreen and Manju. While Manju was definitely born in India the birthplace of Nasreen is tentatively placed by him in southern Iran or Baluchistan. One Indian Manju subclan in India is as old as 73,000 years, whereas European man goes back to less than 50,000 years.
Allegra's Genome.
Now that’s funny!
Bunch of Ukrainian Kossacks spreading their deNAs.
I could have tttold them that for 5 buks.
Wrong, every nation is a nation of colonists.
If I was doing the study, that would have been my conclusion.
> Perhaps they migrated to Europe from Mexico <
In order to do the work hunter-gatherers wouldn’t do?
Oh, I get it, Its the Sock Loving Genome, from ancient Mesopotamia!
LMAO
Spirulina Socatus Mesapotaminia!
Are they N-1s?
Good one Martin!
