Suggested late Neolithic origin of T2f

[razyn]

This information is quoted from a newly published (June, 2015) dissertation by Anna Szécsényi-Nagy, p.97:


Late Neolithic novel haplogroups are the U8, appearing first in the Sopot culture and T2f, emerging in the Lengyel culture...

Haplogroup T2f appeared first in the Körös culture in Hungary, but it was also present in the Alföld-LBK (Keerl, 2014). It reached Central Germany with the earliest farmers (LBK), and persisted in the succeeding Rössen and Schöningen groups as well (Haak et al., 2010, Brandt et al., 2013). Since these T2f haplogroups from Alföld and Germany are the same haplotype that was detected first in the Lengyel period of Transdanubia, it might be just a coincidence, that T2f has not been found yet in the previous SOP, LBKT or STA datasets.

The previous T and J study mentioned only this wrt T2f:


The two subclades of T2f, which dates to ∼17 ka ago, are both recognizable in HVS-I and appear to be almost entirely European, with very minor dispersal back into the Near East, mainly the Levant. T2f1, dating to ∼12 ka ago, is more frequent in north-central Europe but extends across eastern Europe and into central Asia, whereas the younger T2f2, dated to ∼7 ka ago, has a more restricted distribution in Italy, the Balkans, and north of the Black Sea. Moreover, there is a T2f∗ sequence from France.

The previous T and J study mentioned only this wrt T2f:

But note that the date of that study is 2012. I'm T2f3, which was identified more recently. And there are several of us, by now.

T2f2 predicted here, according to the James Lick software. It's rare, FTDNA shows it in the Balkans, Italy, Finland and Germany. Unfortunately, the ancient mtDNA database (https://amtdb.org/records/) doesn't have any hits yet but there are some T2f showing up, in Copper Age Hungary and Germany and in Bronze Age Bulgaria. Seems like a Neolithic Eastern European haplogroup.

Makes me wonder if mine is a later Neolithic arrival as well. Interesting the increase in genetic diversity from EEF-times to the eNeolithic within farmer communities.

First T2f2 in ancient DNA record, from the recent Croatia paper:

It's from the Roman era individual, with suspected Sarmatian paternal ancestry.

Interestingly, none of the newly added Turkish samples (https://www.yfull.com/samples-from-paper/540/?page=1) belong to T2f, even though T2 is well represented in general. So it was either a minor clade in Anatolia and has remained so, or maybe it didn't come to Europe through Anatolia. But not sure how to explain its presence in Central-Eastern Europe during the Neolithic if that's the case.

There are a few examples of T2f from ancient DNA studies, although from the scant references I've seen it's hard to pin them down. Possibly found in southern Germany and/or in Alsace; possibly of the LBK culture, or Cucuteni-Trypillia. Some instances of T2f may be spotted in a couple of paragraphs in the Eupedia essay linked below; I guess that means it's Maciamo Hay's work, updated in 2020. If one scrolls down to his Subclades discussion, phylogenetic table and notes, there are examples (almost certainly modern ones) showing where a subclade has been "found." Those have about as much value or significance as the heat maps on the same site -- which is to say, not all that much. Areas with a concentration of a haplogroup or a subclade in the present day may have very little to do with its neolithic (or earlier) place of origin. But we still don't have very much of the better (ancient) evidence to work with. So, check it out:

I got the FASTA file from my WGS and uploaded to Yfull, I was assigned T2f2* (https://www.yfull.com/mtree/T2f2/)

[peloponnesian]

I formed a clade with a Greek (academic sample) and a Bulgarian, TMRCA 1300 ybp: https://www.yfull.com/mtree/T2f2d/

"Maternal Lineages of Gepids from Transylvania"

T2 decently represented (15%), all are T2b except for a person belonging to T2f1a1 (https://www.yfull.com/mtree/T2f1a1/).

T2f1a1* has also been reported in the papers "Mitogenomic data indicate admixture components of Central-Inner Asian and Srubnaya origin in the conquering Hungarians" (https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0205920) and "Revising mtDNA haplotypes of the ancient Hungarian conquerors with next generation sequencing" (https://pubmed.ncbi.nlm.nih.gov/28422985/).

A male from a Merovingian cemetery in Thuringia (http://dx.doi.org/10.53846/goediss-464) is predicted for T2f2

At this point the vast majority of ancient T2f samples (yfull (https://www.yfull.com/ancient/), amtdb (https://amtdb.org/samples)) are from Hungary, Southeast Germany and surrounding regions (Croatia, Romania).

According to the new paper "Ancient mitochondrial diversity reveals population homogeneity in Neolithic Greece" (https://www.nature.com/articles/s41598-022-16745-8), T2f was found in Mavropigi, Kozani (northern Greece) in the early Neolithic (6038+-21 calBCE). This makes it the oldest T2f found so far. It's possible this could be basal T2f, I hope they get uploaded to Yfull and amtDB when the mitogenomes become available by the authors.
