In human mitochondrial genetics, L is the mitochondrial DNA macro-haplogroup that is at the root of the anatomically modern human (Homo sapiens) mtDNA phylogenetic tree. As such, it represents the most ancestral mitochondrial lineage of all currently living modern humans, also dubbed "Mitochondrial Eve". Its two sub-clades are L1-6 and L0.
Studies of ancient DNA have found H5 in four individuals of around 6800 BC from the Pre-pottery Neolithic B site of Tell Halula, Syria. [6] H5a has been found in a Tagar (800 BC–100 AD) man on the Russian steppe whose Y-DNA was R1a1a [13] and in Margrethe, 11th century AD Queen of Denmark. [14]
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 H is a human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated in West Asia, near present day Syria, [1] around 20,000 to 25,000 years ago. Mitochondrial haplogroup H is today predominantly found in Europe, and is believed to have evolved before the Last Glacial Maximum (LGM).
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.
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.
