There is no indication from the previous mtDNA studies that west Eurasian-specific subclades have evolved within India and played a role in the spread of languages and the origins of the caste system. To address these issues, we have screened 14,198 individuals (4208 from this study) and analyzed 112 mitogenomes (41 new sequences) to trace west Eurasian maternal ancestry. This has led to the identification of two autochthonous subhaplogroups—HV14a1 and U1a1a4, which are likely to have… 

Neolithic phylogenetic continuity inferred from complete mitochondrial DNA sequences in a tribal population of Southern India

The present analysis on complete mtDNA reveals addition information of the spread and distribution of west Eurasian haplogroups in southern India, in tracing an unexplored genetic link between Melakudiya tribe with the people of Iranian Plateau, South Caucasus, and Central Asia.

Rare human mitochondrial HV lineages spread from the Near East and Caucasus during post-LGM and Neolithic expansions

The genetic signatures for distinctive movements out of the Near East and South Caucasus both westward into Europe and eastward into South Asia are found, supporting an origin of HV haplogroup in the region defined by Western Iran, Mesopotamia, and the South Caucasus, where the highest prevalence of Hv has been found.

Carriers of mitochondrial DNA macrohaplogroup R colonized Eurasia and Australasia from a southeast Asia core area

Coeval independently dispersals around 50 kya of the West Asia haplogroup U and the Wallacea haplogroups P points to a halfway core area in southeast Asia as the most probable centre of expansion of macrohaplogroup R, what fits in the phylogeographic pattern of its ancestor, macrohaPLogroup N, for which a northern route and a southeast Asian origin has been already proposed.

Ancient Mitochondrial Genomes Reveal Extensive Genetic Influence of the Steppe Pastoralists in Western Xinjiang

This study provides genetic links for an early existence of the Indo-Iranian language in southwestern Xinjiang and suggests that the existence of Andronovo culture in western Xinjiang involved not only the dispersal of ideas but also population movement.

Untangling Neolithic and Bronze Age mitochondrial lineages in South Asia

This study shows how a detailed mtDNA phylogeographic approach, combining both modern and ancient variation, can provide evidence of population movements, even in a scenario of strong male bias such as in the case of the Bronze Age Steppe dispersals.

Whole mitochondrial genome analysis of the Daur ethnic minority from Hulunbuir in the Inner Mongolia Autonomous Region of China

The whole mtDNA data generated in the present study will augment the existing mtDNA database and provide genetic links between the Daur population and the aborigine peoples from Siberia and the Amur-Ussuri Region.

Genetic perspective of uniparental mitochondrial DNA landscape on the Punjabi population, Pakistan

The vast array of mtDNA variants displayed in this study suggested that the haplogroup composition radiates signals of extensive genetic conglomeration, population admixture and demographic expansion that was equipped with diverse origin, whereas matrilineal gene pool was phylogeographically homogenous across the Punjab.

Genetic analysis of mitochondrial DNA control region variations in four tribes of Khyber Pakhtunkhwa, Pakistan

Pashtun are the composite mosaic of West Eurasian ancestry of numerous geographic origin that received substantial gene flow during different invasive movements and have a high element of the Western provenance.

Origin and spread of human mitochondrial DNA haplogroup U7

These findings imply that the carriers of haplogroup U7 spread to South Asia and Europe before the suggested Bronze Age expansion of Indo-European languages from the Pontic-Caspian Steppe region.

The Genetic Structure of Chinese Hui Ethnic Group Revealed by Complete Mitochondrial Genome Analyses Using Massively Parallel Sequencing

The results demonstrated that Hui group exhibited closer genetic relationships with Chinese Han populations from different regions, which was largely attributable to the widespread of haplogroups D4, D5, M7, B4, and F1 in these populations.

Admixture, migrations, and dispersals in Central Asia: evidence from maternal DNA lineages

The present results suggest that the mtDNA found out of Africa might be the result of a maturation phase, presumably in the Middle East or eastern Africa, that led to haplogroups M and N, and subsequently expanded into Eurasia, yielding a geographically structured group of external branches of these two haplog groups in western and eastern Eurasia.

Mitochondrial DNA signals of late glacial recolonization of Europe from near eastern refugia.

The molecular dissection of mtDNA haplogroup H confirms that the Franco-Cantabrian glacial refuge was a major source for the European gene pool.

Findings have major implications for the origin of Europeans, since they attest that the Franco-Cantabrian refuge area was indeed the source of late-glacial expansions of hunter-gatherers that repopulated much of Central and Northern Europe from ~15,000 years ago.

The utility of detailed local genetic studies within India, without prior assumptions about the importance of Varna rank status for population grouping, is highlighted to obtain new insights into the relative influences of past demographic events for the population structure of the whole of modern India.

The results for Persians and Qashqais point to a continuous increase of the population sizes from ∼24 kya to the present, although the phase between 14- 24 kya is thought to be hyperarid according to the Gulf Oasis model, which can explain the human expansion across the Persian Gulf region.
