New U2 clade found in Europe

New U2 subclade
U2(f): 16092C, 16179A, 152C

mHG U2 has weak presence in Europe (Frequency of 1-2%) European U2 is quite homogeneous, basically all of it is U2e. And U2d covers 99% of other U2 in Europe. So it is worth noting I just discovered a new type of U2 in Europe which is a cousin of U2e and U2d. 

This newly discovered U2 clade has been found in only two populations who live(ed) roughly in the Eastern half of Europe. Below are all the examples of this U2 clade I have found.

5200 BC, Hungary

2013 AD, Bulgaria

Haplogroup U2 breaks up into three branches.
U2-Kostinki: Only example exists; a man who died in Russia 38,000 years ago.
U2a'b: Basically exclusive to South Asia.
U2'c'd'e: U2c peaks in South Asia. U2d and U2e are found everywhere in Eurasia except Eastern Asia.

All three branches probably date more than 40,000 years. An early form of U2e is documented in Paleolithic Western Europe(~30kya). In addition U2e had a presence in Mesolithic Europe. U2(f) most likely belongs to U2'c'd'e. It could have been involved in early European or Western Eurasian human settlements like U2e and U2d.

    1. One of the Neolithic British individuals recently tested by Olalde et al. 2017 belongs to this rare form of U2. So now we do have a high coverage mtDNA sample for this haplogroup.

  2. Where can I get more information about U2d? All 23andme says is that it’s a rare group. Has anyone made a map of the regions it’s found in?
