  • R1b-M269 - the enigmatic man

    R1b-M269’s Most Recent Common Ancestor (MRCA) was a single individual that lived about 4350 BC just prior to the dawn of the Bronze Age. Almost all of his paternal ancestors’ lines were erased. Thirty (30) or more generations of cousins left no survivors. During this time, his single ancestral lineage piled up 97 SNPs to form a very phylogenetic equivalent block. His Y chromosome also had a large deletion. Something significant happened as the use of Bronze metalworking spread to and from the Pontic-Caspian Steppes. The R1b-M269 MRCA descendants expanded rapidly during the Early Bronze Age and were very successful at establishing lineages that survive to this day.

    The R1b-M269 man
    - Is the progenitor of 50% of all men from Europe
    - Has left 99% of all branches within R1b and 40% of all branches on the Giant Y Tree of Mankind
    - Led to cultural changes throughout Europe and eventually the New World including a legacy of Centum based Indo-European languages such as Celtic, Italic (including Romance languages and Latin), Germanic (including English).

    How did this happen? There are many missing pieces to the M269 mans’ puzzle. He remains a mystery. His lack of brother and cousin lineages make him difficult to track during the Neothlic and Chalcolithic times. We don’t know but we search for answers in SE Europe and Eastern Europe in the Steppes above the Black Sea and Caspian Sea.

    The study of SE Europe ancient skeletons by Mathieson, etc. commented about two outlier individuals in Bulgaria.
    I2181 Bulgaria, Smyadovo Late Chalcolithic 4550-4455 BC (male, believed to be M269+)
    ANI163 Bulgaria_Varna_Eneolithic 4711-4542 BC (female)
    “The movements from the Pontic-Caspian steppe of individuals similar to those associated with the Yamnaya Cultural Complex in the 3rd millennium BCE contributed about 75% of the ancestry of individuals associated with the Corded Ware Complex and about 50% of the ancestry of succeeding material cultures such as the Bell Beaker Complex in central Europe.7,15 In two directly dated individuals from southeastern Europe, one (ANI163) from the Varna I cemetery dated to 4711-4550 BCE and one (I2181) from nearby Smyadovo dated to 4550-4450 BCE, we fin d far earlier evidence of steppe-related ancestry (Figure 1B,D). These findings push back the first evidence of steppe-related ancestry this far West in Europe by almost 2,000 years, but it was sporadic as other Copper Age (~5000-4000 BCE) individuals from the Balkans have no evidence of it. Bronze Age (~3400-1100 BCE) individuals do have steppe-related ancestry (we estimate 30%; CI: 26-35%), with the highest proportions in the four latest Balkan Bronze Age individuals in our data (later than ~1700 BCE) and the least in earlier Bronze Age individuals (3400-2500 BCE; Figure 1D).” “Necropolis at Varna, which has some of the earliest evidence of extreme inequality in wealth, with one individual (grave 43) from whom we extracted DNA buried with more gold than is known from any earlier site.” "The Genomic History of Southeastern Europe", Mathieson, et. al., 2018

    "The deceased was a ca 20 years old adult (adultus) and was about 1.72 m tall [5'8"]. The analyses conducted by the physical anthropologists revealed eleven post-mortem trepanations mainly affecting the two parietal bones. One of the trepanations is on the frontal bone, another on the occipital bone, and a third one at the left temporal bone. The trepanations are oval, quadrangular and triangular. A fragmented ceramic vessel was found under the pelvis of the skeleton (fig. 5: 3‑5). On the basis of contextual evidence, the burial could be dated, with great caution, to the post-Chalcolithic period or the beginning of the Early Bronze Age” “Chapter 3. The prehistoric cemetery at Smyadovo, Shumen district“ More discussion is at​​

    Saw this over on FB Mike, great work!! Pictures tell the tale that folks don't often otherwise READ.

    Explaining genetics without pics is a lost cause for me...but I try.

      I'd really enjoy discussing this, but I don't do Facebook anymore.

      The steppe DNA in the Smyadovo sample tells the story, IMHO, that and the fact that Smyadovo is in eastern Bulgaria, not all that far from the west coast of the Black Sea. In other words, Mr. Smyadovo wasn't found all that far from the Pontic-Caspian steppe.

      Archaeologist Marija Gimbutas believed there were three "Kurgan waves" out of the steppe, the first into SE Europe ~4400-4300 BC, which isn't far off I2181's range of dates.

        Figured I would update my R1b-L754 Descendant Tree, since there have been a few new developments since I first put it together back in September of 2022. Here it is.

        It shows where M269 is, so that makes it relevant.

          The primary new additions to the tree above are L761 and FTE1. If you have a Big Y test and ever look at your block tree, you will see there is still a lot of potential for "new" SNPs to break loose and get placed on the tree. Right now most of them are stacked up inside the blocks on the block tree where they are regarded (for now) as roughly equivalent to one another.

          According to FTDNA Discover, right now FTE1 is represented by one man with origins in Tajikistan.

            Of course that Tajik guy isn't really just R1b-FTE1 and nothing else. He's a modern man, after all. He has numerous downstream SNPs. They are considered "private" (unique to him) right now because no one else has tested who shares any of them with him. Guess FTDNA needs to send a team out to Tajikistan to collect some samples, or maybe they could pull some Tajik R1b (or R1b from elsewhere nearby in Central Asia) from the old Genographic Project and test those samples. Wish they would!

              Back in the old days, before the ancient DNA revolution, a lot would have been made of the discovery of an R1b-FTE1 man from Tajikistan in Central Asia. Now we don't put as much stock in modern Y-DNA. Still, it is interesting that the one known carrier of a SNP immediately downstream of L754 (apparently) is of Tajik origin.

                Guess you all have seen the new ancient sample, MN2003, dated 10654-10413 cal BP (~8654-8413 cal BC), from the Posth et al paper, "Palaeogenomics of Upper Palaeolithic to Neolithic European hunter-gatherers" (2023). He's an R1b-P297 recovered at Minino in the Upper Volga in Russia and belonging to the paper's Sidelkino cluster.

                I believe that's the oldest R1b-P297 thus far found.

                  Given that MN2003 is radiocarbon dated to ~8654-8413 cal BC, and according to FTDNA Discover P297 was born about 12000 BC, it seems likely MN2003 is really derived for something downstream of P297, like M269 or M73, or maybe even some other SNP perhaps now extinct or represented by modern men who just haven't been tested yet. Wish they had gotten further with him than just P297.


                  • #10
                    I have been informed by someone who has looked at the BAM file, that MN2003 is M269- and M73- . So, he is R1b-P297*.
