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 mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population geneticists trace the matrilineal inheritance of modern humans back to human origins in Africa and the subsequent spread around the globe.

The letter names of the haplogroups (not just mitochondrial DNA haplogroups) run from A to Z. As haplogroups were named in the order of their discovery, they (meaning the accidental dictionary ordering of the letters) do not reflect the actual genetic relationships.

The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve.

The rate at which mitochondrial DNA mutates is known as the mitochondrial molecular clock. It's an area of ongoing research with one study reporting one mutation per 8000 years.[2] This makes mitochondrial DNA less precise for genealogical dating than Y-chromosome DNA which accumulates one mutation for every 10 years.[3]

mtDNA haplogroup tree and distribution map.[4] The numbers are haplogroup labels, reported according to the http://www.phylotree.org/ nomenclature,[5] and give the location of one of the mutations leading to the derived haplotype. (Only a single branch defining marker, preferably from the coding region, is shown.) The main geographic features of haplogroup distribution are highlighted with colour.

Chronological development of haplogroups[edit]

Estimated world map of human migrations based on mtDNA haplogroups.

Haplogroups present in Europe[edit]

While Bryan Sykes claimed there were seven "daughters" – or major mitochondrial lineages – among modern Europeans (H, J, K, T, V, X and U - essentially subclade U5)[6], other scientists put the number at 10–12 - for instance, Richards et al include I, W and N1b within their pan-european survey (but - illustrating how complex the question can be - also separate out pre-V, HV1 and pre-HV1, and separate out U to include U1, U2, U3, U4 and U7 as well as U5). [7] The additional "daughters" are generally said to include haplogroups I, M and W[citation needed]. A 2012 paper suggested that the haplogroups most common in modern European populations were: H, J, K, N1, T, U4, U5, V, X and W.[8]

Since a single mutation may define a haplogroup, the total number of "European mtDNA haplogroups" – even if they are defined only as those mentioned above and their descendant clades – is ultimately subjective, could theoretically number in the millions, and be continually increasing.[citation needed]

Australian haplogroups[edit]

M42a, M42c, M14, M15, Q, S, O, N, P. (Refs 1,2,3,4,5,6)

M sub groups that are currently identified as specific to Australia are M42a, M42c, M14 and M15. Also Q1, Q1b, Q3a1 in northern Australia (Q is a major sub division of M also found in New Guinea.

N sub-groups are S, O (Australia).

R (itself derived from N) : P N: S & O. S: Haplogroup S has a wide distribution in Australia and has several major subclades, S1, S1a, S1b, S1b1, S1b2, S1b3, S2, S2a, S2b, S3, S4. The ancient matriline, called S1a has been characterised by complete and partial mt genomes in New South Wales, central, western, south Australia, Northern Territory (Refs)and in Tasmania by partial sequences (ref 8) O haplogroup: O1, O2 identified by complete mt genome have been identified in southern, northern and western Australia.

P haplogroup:

Widespread in PNG, Timor (Ref 7), northern and eastern Australia. The Darling River region of NSW has a distinctive sub-clade called

P4b (now called P11), further diversified by into several distinct but culturally connected family lineages (van Holst Pellekaan 2011) and 2013.
