Haplogroup N1a is a human mitochondrial DNA (mtDNA) haplogroup.
Origin
N1a originated in the Near East {{cite journal |first1=Martin |last1=Richards |first2=Vincent |last2=Macaulay |first3=Eileen |last3=Hickey |first4=Emilce |last4=Vega |first5=Bryan |last5=Sykes |first6=Valentina |last6=Guida |first7=Chiara |last7=Rengo |first8=Daniele |last8=Sellitto |first9=Fulvio |last10=Kivisild |first10=Toomas |last11=Villems |first11=Richard |last12=Thomas |first12=Mark |last13=Rychkov |first13=Serge |last14=Rychkov |first14=Oksana |last15=Rychkov |first15=Yuri |last16=Gölge |first16=Mukaddes |last17=Dimitrov |first17=Dimitar |last18=Hill |first18=Emmeline |last19=Bradley |first19=Dan |last20=Romano |first20=Valentino |last21=Calì |first21=Francesco |last22=Vona |first22=Giuseppe |last23=Demaine |first23=Andrew |last24=Papiha |first24=Surinder |last25=Triantaphyllidis |first25=Costas |last26=Stefanescu |first26=Gheorghe |last27=Hatina |first27=Jiři |last28=Belledi |first28=Michele |last29=Di Rienzo |first29=Anna |last30=Novelletto |first30=Andrea |last9=Cruciani |title=Tracing European Founder Lineages in the Near Eastern mtDNA Pool |journal=American Journal of Human Genetics |issn = 0002-9297 |volume=67 |issue=5 |pages=1251–76 |date=16 October 2000 |pmid=11032788 |pmc=1288566 |doi=10.1016/S0002-9297(07)62954-1|display-authors=8 }} 12,000 to 32,000 years ago. Specifically, the Arabian Peninsula is postulated as the geographic origin of N1a. This supposition is based on the relatively high frequency and genetic diversity of N1a in modern populations of the peninsula.{{cite book |last1=Petraglia |first1=Michael |first2=Jeffrey |last2=Rose |title=The Evolution of Human Populations in Arabia: Paleoenvironments, Prehistory and Genetics |publisher=Springer |year=2009 |pages=82–3 |url=https://books.google.com/books?id=x6o4XLIKN0UC |isbn=978-90-481-2719-1}} Exact origins and migration patterns of this haplogroup are still subject of some debate.
=Debate on Origin of Neolithic Europeans=
Two main competing scenarios exist for the spread of the Neolithic package from the Near East to Europe: demic diffusion (in which agriculture was brought by farmers) or cultural diffusion (in which agriculture was spread through the passage of ideas).
N1a became particularly prominent in this debate when a team led by Wolfgang Haak analyzed skeletons from Linear Pottery Culture sites. The Linear Pottery Culture is credited with the first farming communities in Central Europe, marking the beginning of Neolithic Europe in the region some 7500 years ago. As of 2010, mitochondrial DNA analysis has been conducted on 42 specimens from five locations. Seven of these ancient individuals were found to belong to haplogroup N1a{{cite journal |first1=Wolfgang |last1=Haak |first2=Peter |last2=Forster |first3=Barbara |last3=Bramanti |first4=Shuichi |last4=Matsumura |first5=Guido |last5=Brandt |first6=Marc |last6=Tänzer |first7=Richard |last7=Villems |first8=Colin |last8=Renfrew |first9=Detlef |last10=Alt |first10=K.

A separate study analyzed 22 skeletons from European hunter-gatherer sites dated 13400-2300 BC. Most of these fossils carried the mtDNA haplogroup U, which was not found in any of the Linear Pottery Culture sites. Conversely, N1a was not identified in any of the hunter-gatherer fossils, indicating a genetic distinction between Early European Farmers and late European hunter-gatherers.{{cite journal |last1=Bramanti |first1=Barbara |last2=Thomas |first2=M. |last3=Haak |first3=Wolfgang |last4=Unterlaender |first4=M. |last5=Jores |first5=P. |last6=Tambets |first6=K. |last7=Antanaitis-Jacobs |first7=I. |last8=Haidle |first8=M. |last9=Jankauskas |first9=R. |last10=Kind |first10=C.-J. |last11=Lueth |first11=F. |last12=Terberger |first12=T. |last13=Hiller |first13=J. |last14=Matsumura |first14=S. |last15=Forster |first15=P. |last16=Burger |first16=J. |title=Genetic Discontinuity Between Local Hunter-Gatherers and Central Europe's First Farmers |journal=Science |volume=326 |issue=5949 |pages=137–40 |year=2009 |pmid=19729620 |doi=10.1126/science.1176869|display-authors=8 |bibcode=2009Sci...326..137B |s2cid=206521424 |doi-access=free }}
Haak's team concludes that "the transition to farming in central Europe was accompanied by a substantial influx of people from outside the region." However, they note that haplogroup frequencies in modern Europeans are substantially different from early farming and late hunter-gatherer populations. This indicates that "the diversity observed today cannot be explained by admixture between hunter-gatherers and early farmers alone" and that "major demographic events continued to take place in Europe after the early Neolithic."
Critics of these studies claim that the LBK N1a specimens could have derived from local communities established in Europe before the introduction of farming. Ammerman's team voiced concern due to some of the LBK specimens coming from communities several hundred years after farming was first established in the region;{{cite journal |first1=Albert J. |last1=Ammerman |first2=Ron |last2=Pinhasi |first3=Eszter |last3=Bánffy |author-link3=Eszter Bánffy |title=Comment on 'Ancient DNA from the First European Farmers in 7500-Year-Old Neolithic Sites' |journal=Science |volume=312 |issue=5782 |pages=1875 |year=2006 |pmid=16809513 |doi=10.1126/science.1123936 |bibcode=2006Sci...312.....A |doi-access= }} a rebuttal was given.{{cite journal |first1=Joachim |last1=Burger |first2=Detlef |last2=Gronenborn |first3=Peter |last3=Forster |first4=Shuichi |last4=Matsumura |first5=Barbara |last5=Bramanti |first6=Wolfgang |last6=Haak |title=Response to Comment on 'Ancient DNA from the First European Farmers in 7500-Year-Old Neolithic Sites' |journal=Science |volume=312 |issue=5782 |pages=1875 |year=2006 |pmid= |doi=10.1126/science.1123984|bibcode=2006Sci...312.....B |s2cid=220083496 }}
In 2010, researchers led by Palanichamy conducted a genetic and phylogeographic analysis of N1a. Based on the results, they conclude that some of the LBK samples were indigenous to Europe while others may have resulted from 'leapfrog' colonization. Deguilloux's team agreed with Haak's conclusion on a genetic discontinuity between ancient and modern Europeans. However, they consider demic diffusion, cultural diffusion, and long-distance matrimonial exchanges all equally plausible explanations for the current genetic findings.
Ancient DNA
Seven of 42 skeletons from Linear Pottery Culture (Linearbandkeramik) sites were found to be members of the N1a haplogroup (see Neolithic European).

Distribution
Haplogroup N1a is widely distributed throughout Europe, Northeast Africa, the Near East and Central Asia. It is divided into the European/Central Asian and African/South Asian branches based on specific genetic markers.

In Kenya, the haplogroup is carried by around 10% of the Cushitic-speaking Rendille, as well as 1% of the Maasai.

The tree of N1a has two distinct branches: Africa/South Asia and Europe with a Central Asian subcluster. However, the African branch has members in southern Europe, and the European branch has members in Egypt and the Near East. The Africa/South Asia branch is characterized by the 16147G mutation, whereas the European branch is characterized by 16147A, 3336 and 16320. The Central Asian subcluster is an offshoot of the European branch that is characterized by marker 16189.
Subclade N1a1 is associated with mutation 16147A. Palanichamy calculates N1a1 to have emerged between 8900 and 22400 YBP (Years Before Present). Subclade N1a1a is denoted by marker 16320, and is therefore associated with the European N1a branch. Petraglia estimates that N1a1a arose between 11000 and 25000 YBP.
