Where did I2 haplogroup come from?
Haplogroup I-M438, also known as I2 (ISOGG 2019), is a human DNA Y-chromosome haplogroup, a subclade of Haplogroup I-M170. Haplogroup I-M438 originated some time around 26,000–31,000 BCE. It originated in Europe and developed into several main subgroups : I2-M438*, I2a-L460, I2b-L415 and I2c-L596.
What is the DNA of Brahman?
The study identified the deep ancient origins of Brahmins by tracing their Y-chromosome haplogroups and genetic markers on the Y-DNA phylogenetic tree. It was confirmed that the progenitors of this group emerged from at least 12 different geographic regions of the world.
What is my haplogroup?
Your haplogroup is a clue to your maternal or paternal ancestry. Your maternal haplogroup is assigned by identifying a set of variants in your mitochondrial DNA. If you are male, your paternal haplogroup is assigned by identifying a set of variants in your Y-chromosome DNA as well.
What is the origin of R1a1a?
Spencer Wells proposes Central Asian origins, suggesting that the distribution and age of R1a1 points to an ancient migration corresponding to the spread by the Kurgan people in their expansion from the Eurasian steppe. According to Pamjav et al. (2012), R1a1a diversified in the Eurasian Steppes or the Middle East and Caucasus region:
Where is the r1a1-z280 lineage?
Inner and Central Asia is an overlap zone for the R1a1-Z280 and R1a1-Z93 lineages [which] implies that an early differentiation zone of R1a1-M198 conceivably occurred somewhere within the Eurasian Steppes or the Middle East and Caucasus region as they lie between South Asia and Central- and Eastern Europe.”
What is the difference between R1a1a and M417?
While R1a originated ca. 22,000 to 25,000 years ago, its subclade M417 (R1a1a1) diversified ca. 5,800 years ago. The place of origin of the subclade plays a role in the debate about the origins of Proto-Indo-Europeans .
How many branches are there in the R1a family tree?
The R1a family tree now has three major levels of branching, with the largest number of defined subclades within the dominant and best known branch, R1a1a (which will be found with various names such as “R1a1” in relatively recent but not the latest literature).
