This research investigates the genetic origins of the Marsh Arabs of Iraq, believed to have strong ties to the ancient Sumerians. By analyzing Y-chromosome and mitochondrial DNA from 143 Marsh Arabs and comparing them to a larger Iraqi control group, the study reveals a predominantly Middle Eastern genetic heritage with minor contributions from Southwest Asia and Africa. Notably, a specific Y-chromosome lineage (J1-Page08) shows expansion concurrent with the Sumerian period, suggesting a potential genetic link. While the introduction of water buffalo farming appears to have had limited impact on the gene pool, the findings support the hypothesis that the Sumerians were likely autochthonous to the region, rather than originating from India or South Asia.
Haplogroup Q-Y2197, also known as Haplogroup Q-M242, is a genealogical group of lineages defined by unique genetic markers present on the Y-chromosome. It's commonly found among populations in the United Kingdom and Ireland and is linked to the Marsh Arab population in Mesopotamia.
A detailed phylogenetic tree representing the haplogroup Q-Y2197, showing its subclades, estimated ages, and associated sample IDs. It visualizes the relationships between individuals carrying this haplogroup based on SNP data.
This FamilyTreeDNA page details the haplogroup Q-Y2197, tracing its origins back to an ancestor around 200 CE who branched off from Q-Y2232. The most recent common ancestor of the Q-Y2197 lineage is estimated to have lived around 400 CE, with a 95% probability range of 83-662 CE. Currently, there are 697 tested descendants, primarily originating from Poland, Ukraine, and Lithuania, with connections to historical regions like India and Central Asia. The platform encourages further testing to refine the family tree and age estimates, offering tools to explore branches and connect with relatives.
