After the mostly Mesopotamian and Neolithic haplogroup HV, here comes the history of haplogroup U3, another Middle Eastern lineage but with a much more recent expansion (Chalcolithic to Iron Age) and a closer association with Y-haplogroups J1(xP58) and J2. U3 is also a major Romani/Gypsy lineage...

MtDNA haplogroup I may improve light absorbtion and sleep & cut risk of schizophrenia I have noticed that haplogroup I (mtDNA) is defined by a rare mutation (T10034C) in tRNA encoding Glycine. This amino acid is a known an inhibitory neurotransmitter in the central nervous system, especially...

I have been quite busy in the last few months, but I finally found some time to write a new haplogroup page. Here comes Haplogroup HV.

Here is a new paper by Daniel Gómez-Sánchez and co-workers. They tested 19 mitochondrial sequences from the Burgos region in Castile and León, northern Spain, all dating from the late Copper Age (2050 to 2500 BCE). The authors note the heterogeneity of mt-haplogroups compared to other...

Hi, I participated in a mtDNA study and my results are L3D3 or H5,with the explanation that, given the fact that I am Romanian, H5 is the haplogroup that characterises me (H5 being dominant in Romania), but also, given my mutations, I can be situated in L3D3 haplogroup. What does this means...

An analysis of the mitochondrial DNA of living lions and museum specimens conducted by Ross Barnett of Durham University and his colleagues reveal that the most recent common maternal ancestor of modern lions lived around 124,000 years ago. The study tested the DNA of extinct Barbary...

While analysing the mtDNA phylogeny, I noticed that most of the common, successful mitochondrial haplogroups were defined by a new mutation in the Coenzyme Q - cytochrome c reductase gene (MT-CYB) encoding the Cytochrome b protein, located between positions 14,747 and 15,887 in the mtDNA...

If you are following Eupedia on Facebook or Twitter, you will have noticed that I have been working for the last 6 weeks of so on writing pages for European mitochondrial haplogroups. I haven't quite finished yet. Haplogroups I, U2 and U3 should follow soon. Here is the list of the new pages...

I am starting to get annoyed by the number of useless studies published recently in the field of population genetics that do not tell us anything that we didn't already know, and do not provide any worthwhile new data (e.g. Pickrell et al. 2014, Sverrisdóttir et al. 2014, Pierron et al. 2013...

Looking for help finding out more about Haplogroup T2d1. My mother's grandparents are all from Poland but all the tests I have done say my mtDNA hg is T2d1 or T2d1b. However there is nothing about this subclade that I can fin. Any help on where to look next would be appreciated.

The North Caucasus has a very unique genetic landscape. The mitochondrial haplogroups found there, especially in the Northwest Caucasus include a lot of rare lineages that aren't found at higher frequencies almost anywhere else. These include haplogroups H2a1, I (mostly the I1, I2 and I4a...

I have recently proposed a novel theory regarding the origins of haplogroup R1b. I believe that R1b1 (P25) people might have been among the first people to domesticate cattle in eastern Anatolia and northern Mesopotamia/Syria during the Pre-Pottery Neolithic period. I suggested that the P297...

A recent paper on Madagascar Y-DNA and mtDNA made me realise that Y-haplogroups J1 and T1 probably both spread from the northern Zagros after having become nomadic herders during the Pre-Pottery Neolithic. Both haplogroups are usually found together in Europe, in the Arabian peninsula, Egypt...

Mitochondrial DNA is responsible for energy production in cells. If Mt Hg U is European paleolithic one, existed in Europe during Ice Age, it would make sense to conclude that it was the best haplogroup to have for cold climate. Theoretically it produces more energy, body heat, than others...

Is it possible to link a mtDNA with an ancient tribe? Like haplogroup I1 is linked to pre-Germanic peoples of Scandinavia, like R1b-S21 is linked to the ancient continental Germanic peoples, R1b-S28 to Proto-Italo-Celts, R1b-L21 to Atlanto-Celts, N1c1 to Finno-Ugric and Baltic peoples...

I have created a map showing the distribution of East & North Asian (Mongoloid) mtDNA haplogroups in Europe and the Middle East. This includes haplogroups A, B, C, D, E, F, G, M7, M8, Y and Z. ANALYSIS: Western Europe Western Europe has the lowest percentage of East Asian haplogroups, with...

Dear Maciamo, I appreciate the substantial amount of time you dedicate on creating these great haplogroup distribution maps and I understand how hard it must be to go through all the evidence and get it right for every single region in Europe. I could see from your mt-DNA maps that the data for...

MtDNA haplogroup L is the oldest maternal branch of humanity comprises almost all the lineages in sub-Saharan Africa. All Eurasian haplogroups descend from L3, the subclade that is the most common in the Arabian peninsula and North-East Africa. All four top branches of L (L0, L1, L2 and L3) are...

Haplogroup H5 is thought to have originated around 12,000 years ago in West Asia, probably around the Fertile Crescent. It was found in four individuals of from the Pre-Pottery Neolithic B site of Tell Halula in Syria, dating from circa 6800 BCE. It was also found in Neolithic Germany, Minoan...

Haplogroup T1 is a maternal lineage which appears to have originated in the Fertile Crescent and/or the South Caucasus. It is strongly associated with the expansion of agriculture during the Neolithic period, and to a lesser extent also with the spread of the Indo-Europeans during the Bronze...
