Haplogroup R0 derives from the macro-haplogroup R.It is an ancestral clade to the R0a subclade and haplogroup HV, and is therefore antecedent to the haplogroups H and V.. R0's greater subclade variety in the Arabian Peninsula suggests that the clade originated in and spread from there.

In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the ...
The mitochondrial DNA variation in isolated "relict" populations in southeast Asia supports the view that there was only a single dispersal from Africa. [15] The distribution of the earliest branches within haplogroups M, N, and R across Eurasia and Oceania provides additional evidence for a three-founder-mtDNA scenario and a single migration ...
Haplogroup U is a human mitochondrial DNA haplogroup (mtDNA). The clade arose from haplogroup R, likely during the early Upper Paleolithic.Its various subclades (labelled U1–U9, diverging over the course of the Upper Paleolithic) are found widely distributed across Northern and Eastern Europe, Central, Western and South Asia, as well as North Africa, the Horn of Africa, and the Canary Islands.
Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of sub-Saharan Africa. [4] Haplogroup R is a descendant of the macro-haplogroup N.
In humans, mitochondrial DNA (mtDNA) forms closed circular molecules that contain 16,569 [4] [5] DNA base pairs, [6] with each such molecule normally containing a full set of the mitochondrial genes. Each human mitochondrion contains, on average, approximately 5 such mtDNA molecules, with the quantity ranging between 1 and 15. [ 6 ]
However, the extant diversity of mitochondrial genomes that belong to Haplogroup A is low relative to the degree of divergence from its nearest outgroups in haplogroup N, which suggests that extant members of Haplogroup A might be descended from a population that has emerged from a bottleneck approximately 20,000 years ago.
Haplogroup X is a human mitochondrial DNA (mtDNA) haplogroup. It is found in North America, Europe, Western Asia, North Africa, and the Horn of Africa. A mtDNA-based map of major human migrations. Haplogroup X diverged from haplogroup N roughly 30,000 years ago (just prior to or during the Last Glacial Maximum).
