I have created a new map combining most Germanic lineages associated with the diffusion Germanic peoples from the Iron Age onwards. These includes Y-DNA haplogroups I1 (except some subclades of Finnish origin), I2-M223, R1a-Z284, R1b-U106, and R1b-L238.

I have started working on a new project: the Genetic History of Italy. The first section includes a summary of the various peoples who came to settle in Italy since the Palaeolithic and the Y-DNA haplogroup that they (probably) brought with them. This section isn't finished yet. I still have...

I was wondering how close do the results have to be to determine a close match. we are all tested positive E1b1b1 E-M35 E-M78- E-V13. Our results are below. Most Distant Ancestor of Country of Origin are different. Italy- 13 25 13 10 16-21 11 12 12 13 11...

Here is the breakdown of J2 subclades by province based on the recent study by Boattini et al.. North Italy In Cuneo, south-west Piedmont, 2 out of 30 samples are J2 (6.5%), both J2a*. In Savona/Genova, central Liguria, 7 out of 50 samples are J2 (14%), among which three J2a*, two J2a2-M67...

The new paper by Boattini et al. is the first Italy-wide study to report haplogroup T separately from K (along with Brisighelli et al. 2012, which reported it as K2). It therefore provides valuable insight into this little studied haplogroup. The sample sizes for each province tested is...

Haplogroup I1 is a marker of Germanic migrations to Italy. The Ostrogoths, Vandals, Lombards, Franks and Normans all left some I1 lineages behind them. The distribution of I1 is fairly homogeneous all over Italy, usually ranging from 1 to 5%. I had a look at the new study by Boattini et al. to...

Haplogroup J1 is found at relatively low frequencies in Europe, except in Italy and Greece. The new study by Boattini et al. provides new insight into the distribution of J1 and its subclades in Italy. The highest concentration is found in Agrigento (12%) in southwest Sicily, most probably due...

I have calculated the provincial percentages of G2a in Italy based on the recent study by Boattini et al. The new data significantly alters the known distribution of G2a across the peninsula. Extremely high frequencies (20-25%) were observed in Abruzzo, Molise, Basilicata and Calabria. The...

Here is the breakdown of E1b1b subclades by province based on the recent study by Boattini et al.. North Italy In Cuneo, south-west Piedmont, 2 out of 30 samples are E1b1b (6.5%), among which one E-V13 (3.5%) and one E-V65 (3.5%). In Savona/Genova, central Liguria, 8 out of 50 samples are...

I have counted the samples for each R1b subclade in the new study of Italian Y-chromosomes by Boattini et al. and calculated the percentages for R1b for each province. The two most interesting R1b subclades in Italy are R1b-U152, which I believe to be associated with the Italic migrations, and...

A new article in Nature revealed that Carsten Pusch from the University of Tübingen managed to sequence the DNA of an ancient Egyptian mummy. Sadly the article doesn't give more information about the identity or age of the mummy, but there is a fleeting mention that the man belonged to...

Yaan pointed me to this 2012 paper by Mrsic et al. They tested the Y chromosomes of 1100 Croatian men, 220 for each of the five regions. This allowed me to recalculate the haplogroup frequencies more accurately. So far, the small studies by Pericic et al. (2005) and Battaglia et al. (2008) only...

PLOS ONE just released Y-Chromosome Diversity in Modern Bulgarians: New Clues about Their Ancestry by Karachanak et al. Bulgaria was relatively undersampled to this day. This study, sampling 808 lineages from each of the 9 Bulgarian provinces, will provide valuable new insight, especially since...

A very exciting new paper was released yesterday, confirming the announcement four months ago that the common ancestor to all human male lineages lived much longer ago than what believed so far. An African American Paternal Lineage Adds an Extremely Ancient Root to the Human Y Chromosome...

There is little doubt now that haplogroup G was one of the main lineages of the people who spread agriculture from the Levant to the Middle East and Europe. Early farming arose in the Levant, and the highest genetic diversity for haplogroup G is also found in the Levant. The odd thing is that hg...

Bekada et al. published a new study looking at the Y-chromosomes of 156 Algerian men as well as 240 mitochondrial lineages. This is not much, but the study also provides data from other studies with substantial sample sizes for Morocco (n=760) and Tunisia (n=601). The results are not very...

Here is the third and final map in my new series designed to show the three major components of the European population. The first map, representing all subclades of Haplogroup I, i.e. the lineages descended from the Palaeolithic and Mesolithic inhabitants of Europe. The second combined...

After the map of Haplogroup I, here is the map of Haplogroup R1. Since both R1a and R1b are associated with the spread of Indo-European languages, it is easy to visualise why almost all Europeans speak IE languages, but North Africans and Middle Easterners don't (apart from the Armenians, who...

I have merged the maps of Y-haplogroups I1, I2a1 (former I2a) and I2a2 (former I2b). Here is what it looks like.

We have discussed this topic extensively in various threads on the forum over the years, but there doesn't seem to be one thread dedicated to the subject. I will summarise my thoughts here so that I don't have to repeat myself every time. As I have explained in my R1b history, between 2500 and...
