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… Expand
Neolithic phylogenetic continuity inferred from complete mitochondrial DNA sequences in a tribal population of Southern India
TLDR
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. Expand
Rare human mitochondrial HV lineages spread from the Near East and Caucasus during post-LGM and Neolithic expansions
TLDR
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. Expand
Carriers of mitochondrial DNA macrohaplogroup R colonized Eurasia and Australasia from a southeast Asia core area
TLDR
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
  • C. Ning, Hong-Xiang Zheng, +9 authors Yinqiu Cui
  • Medicine
  • Frontiers in Genetics
  • 2021
TLDR
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. Expand
Untangling Neolithic and Bronze Age mitochondrial lineages in South Asia
TLDR
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. Expand
Genetic perspective of uniparental mitochondrial DNA landscape on the Punjabi population, Pakistan
TLDR
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. Expand
Mitogenomics of modern Mongolic-speaking populations.
TLDR
It is shown that along with very high levels of genetic diversity and lack of genetic differentiation, Mongolic-speaking populations exhibit strong genetic resemblance to East Asian populations of Chinese, Japanese, and Uyghurs. Expand
Genetic analysis of mitochondrial DNA control region variations in four tribes of Khyber Pakhtunkhwa, Pakistan
TLDR
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. Expand
A genetic chronology for the Indian Subcontinent points to heavily sex-biased dispersals
TLDR
Maternal lineages primarily reflect earlier, pre-Holocene processes, and paternal lineages predominantly episodes within the last 10 ka, which are consistent with the patriarchal, patrilocal and patrilineal social structure of early Indo-European society. Expand
Origin and spread of human mitochondrial DNA haplogroup U7
TLDR
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. Expand

Distinctive Paleo-Indian Migration Routes from Beringia Marked by Two Rare mtDNA Haplogroups
TLDR
A dual origin for the first Americans is a striking novelty from the genetic point of view, and it makes plausible a scenario positing that within a rather short period of time, there may have been several entries into the Americas from a dynamically changing Beringian source. Expand
The Arabian cradle: mitochondrial relicts of the first steps along the southern route out of Africa.
TLDR
Analysis of three minor west-Eurasian haplogroups shows that they have a relict distribution that suggests an ancient ancestry within the Arabian Peninsula, and they most likely spread from the Gulf Oasis region toward the Near East and Europe during the pluvial period 55-24 ka ago. Expand
Admixture, migrations, and dispersals in Central Asia: evidence from maternal DNA lineages
TLDR
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. Expand
Mitochondrial DNA signals of late glacial recolonization of Europe from near eastern refugia.
TLDR
It is reported that a substantial, perhaps predominant, signal from mitochondrial haplogroups J and T, previously thought to have spread primarily from the Near East into Europe with the Neolithic population, may in fact reflect dispersals during the Late Glacial period, ∼19-12 thousand years (ka) ago. Expand
The molecular dissection of mtDNA haplogroup H confirms that the Franco-Cantabrian glacial refuge was a major source for the European gene pool.
TLDR
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. Expand
Population Differentiation of Southern Indian Male Lineages Correlates with Agricultural Expansions Predating the Caste System
TLDR
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. Expand
Complete Mitochondrial DNA Diversity in Iranians
TLDR
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. Expand
Ancient Migratory Events in the Middle East: New Clues from the Y-Chromosome Variation of Modern Iranians
TLDR
AMOVA analysis revealed that language, in addition to geography, has played an important role in shaping the nowadays Iranian gene pool, useful for depicting a more comprehensive history of the peoples of this area as well as for reconstructing ancient migration routes. Expand
Internal diversification of mitochondrial haplogroup R0a reveals post-last glacial maximum demographic expansions in South Arabia.
TLDR
It is shown that the post-Last Glacial Maximum period of the past 20,000 years has been a significant time in the formation of the extant genetic composition and population structure of this region. Expand
Origin and expansion of haplogroup H, the dominant human mitochondrial DNA lineage in West Eurasia: the Near Eastern and Caucasian perspective.
TLDR
The phylogeography of hg H in the populations of the Near East and the Caucasus is described, showing how most of the present-day Near Eastern-Caucasus area variants of hG H started to expand after the last glacial maximum (LGM) and presumably before the Holocene. Expand
