Research Milestones

MAY 2005

Haplogroup I-L38, then called I(x), was first described in May 2005 on the Genealogy-DNA list at Rootsweb.com. This consisted of several conversations between (haplogroup J expert) Bonnie Schrack and (haplogroup I expert) Ken Nordtvedt.

Bonnie Schrack wrote on the 23rd of May a message with the subject: "New cluster? (was maybe I1b, maybe J2)".

In this mail the STR characteristics of I-L38 were pinpointed right from the start:

... -- this is exciting! We seem to have a new cluster here. Not quite as rare a haplotype as we had thought. Each and every one of these haplotypes I've selected from the results list have the 8 10 10 12 at 459a,b, 455 and 454. ... Eight have been tested at YCAII and 7 of those have 19,19.

MAY 2006

In his doctoral dissertation Felix Schilz published STR values of bronze age bones out of the Lichtenstein cave in Osterode-am-Harz, Germany.

JANUARY 2007

Jim Cullen identified the Lichtenstein samples as I1b2 (as I-L38 was called then).

2008

Ken Nordtvedts’ 2008 modal values spreadsheet determines 3 I2b*-STR clusters,A-, B- and C- separated by DYS448.

On a SNP level, it only was known at this time that I2b* was S23+, S30+, S32+, S33+; but M223-.

Comparing STR values Ken Nordtvedt calculated that I2b* originated about 4500 years ago.

SEPTEMBER 2008

Hans De Beule wrote an article on I-L38: Origin, Distribution and Migrations of I2b*-Subclades; publishing a median joining network and the first distribution map; both based on SMGF and Ysearch data. The frequencies and STR diversity drew special attention to the UpperRhine region. Later this article was followed by others - all articles were published together in http://rjgg.molgen.org/index.php/RJGG/issue/view/11/showToc and http://rjgg.molgen.org/index.php/RJGG/article/view/92

25 DECEMBER 2008

The SNPs L38/S154, L39/S155, L40/S156, L65/S159 were added to the ISOGG tree thus creating a new branch I2b2 (or I-L38).

FEBRUARY 2009

Tim Weakley started the FTDNA I2b2-project (as I-L38 was called then) - 38 members joined the first month.

2010

Hans De Beule set up this Website dedicated to I-L38 to harbour the latests finds on I-L38.

MAY 2012

In 2012 it became clear that SNP L533 separates I-L38. I-L533 was the first known subclade of I-L38.

AUGUST 2013

The 23andme results of two I-L38 project members: Stephen Prata and Andy Marotta, showed they shared the same L69 mutation, making I-L69 the second known subclade of I-L38.

SEPTEMBER 2013

One of the FTDNA I-L38 project members (Deterding) took the Geno2.0 test and turned out to be F780, indicating a possible 3rd subclade of I-L38.

NOVEMBER 2013

Ken Nordtvedt published a I-L38 STR tree at his website.

http://knordtvedt.home.bresnan.net/ - the website is temporarily removed at the moment

FEBRUARY 2014

Britain DNA published the Chromo2 results (14.200 SNPs) results of 2000 anonymized samples; 14 of the 2000 samples belonged to haplogroup I-L38/I-S155. Fifteen mutations separated this I-L38 group: S2606; S24121, S2488; S10269; S11558; S12480; S12547; S15855; S19763; S21118; S22679; S24647; S25490; S27697; S4556

JUNE 2014

Based on the Britain DNA data Ken Nordtvedt published a Chromo 2.0 L39/40 SNP network at his website .

JANUARY 2014

Stephen Prata added an extended I-L38 network analysis to the I-L38 website

https://sites.google.com/site/haplogroupil38/median-networks

NOVEMBER 2014

Hans De Beule requested ISOGG to add S2606, S24121 and F780 to the ISOGG tree, thus linking the ISOGG tree to recent FTDNA and Britain DNA results.

JANUARY 2015

FTDNA I-L38 members were regrouped (from a STR based grouping to a SNP based grouping).

APRIL 2015

The FTDNA I-L38 project welcomes its 300th member (Mr. Volokhin)

JULY 2015

Stephen Ralls added a research paper to the I-L38 website describing how I-L38 (21-14) is determined by SNP block SUR66-69.

Later YFull would label this group I-Y18919 (see jan 2016).

OCTOBER 2015

Mikhael Arzamanov points to the facts that the FTDNA Volga Tatar project contains several I-L38 members that have a characteric DYS439=10 value.This group appears to be the most eastern I-L38 branch.

JANUARY 2016

YFull launches version 4.01 of its experimental tree. Thanks to uploaded BigY results of I-L38 project members the resolution of the I-L38 tree has increased greatly. Among others Y18919, Y18921 and PH1237 were added to the tree.

MARCH 2016

Checking the SNP values of sample ESP2/I0114 mentioned in the Haak (2015) en Mathieson (2015) papers; Hans De Beule found out that the I0114 "I2a2"-labeled aDNA sample (of a 4100 years old individual from Esperdstedt), in fact belongs to haplogroup I2a2b-L39.

APRIL 2016

On request of Hans De Beule, YFull created a I-L38 project. Most BigY's if the I-L38 project uploaded their results to YFull enriching the I-L38 tree tremendously.

SEPTEMBER 2016

In a mail correspondence between Bernie Cullen, Zdenko Markovic, Michael Sager (FTDNA), Diogenes Grassal and Hans De Beule a "proto-L38" I2a2b branch was identified. In its 4.09 tree, YFull named this branch I-Y10705.

MARCH 2017

The FTDNA I-L38 SNP Pack was released (this pack was made by Hans De Beule and Michael Sager (FTDNA), basicly it contained all SNPs that were shown in the YFull tree. This popular test resulted in a lot of SNP confirmed samples.

SUMMER 2017

New I-L38 BigY tests resulted in an increased resolution of the I-L38 tree.

SEPTEMBER 2017

Hans De Beule became an ISOGG contributor for the I2a2b branch, all known YFull and FTDNA SNPs were added to the ISOGG tree (which is important since the ISOGG tree is used as a scientific reference to label aDNA samples).

DECEMBER 2017

Atanas Kumbarov identified a I-Y10705 aDNA sample (I4971)) from the Körös culture (Hungary) as a I-Y10705 sample.

JANUARY 2018

Milos Cetkovic Gentula and Aco Nevski integrated the BY14072, S24121, PH1237, BY1183, S2488 subbranches in their nevgen-predictor (http://www.nevgen.org/). The nevgen predictor was used to reorganize the FTDNA groups of samples without a terminal SNP.

MARCH 2018

Screening the BAM files of research paper of Mathieson, and Olalde) Hans De Beule identified two more aDNA I-Y10705 samples: I4915 (9300 - 8000 ya; Hadučka Vodenica, Serbia) (Mathieson, 2018) and I2977 (5000 - 4700 ya; Isbister, Orkney, Scotland) (Olalde, 2018).
