We present 42 new Y-chromosomal sequences from diverse Indian tribal and non-tribal populations, including the Jarawa and Onge from the Andaman Islands, which are analysed within a calibrated Y-chromosomal phylogeny incorporating South Asian (in total 305 individuals) and worldwide (in total 1286 individuals) data from the 1000 Genomes Project. In contrast to the more ancient ancestry in the South than in the North that has been claimed, we detected very similar coalescence times within… 

A comprehensive portrait of Y-STR diversity of Indian populations and comparison with 129 worldwide populations

TLDR
This study genotyped 407 unrelated male individuals from 12 states in India employing the suite of Y-STRs present in PowerPlex Y23 and showed genetic affinity of the Indian populations with few populations from Europe and Levantine.

A Southeast Asian origin for present-day non-African human Y chromosomes

TLDR
It is shown that phylogenetic analyses of haplogroup C, D and FT sequences, including very rare deep-rooting lineages, together with phylogeographic analyses of ancient and present-day non- African Y chromosomes, all point to East/Southeast Asia as the origin 50,000–55,000 years ago of all known surviving non-African male lineages (apart from recent migrants).

Early replacement of West Eurasian male Y chromosomes from the east

TLDR
It is shown that phylogenetic analyses of haplogroup C, D and FT sequences, including very rare deep-rooting lineages, together with phylogeographic analyses of ancient and present-day non- African Y-chromosomes, all point to East/South-east Asia as the origin 50,000-55,000 years ago of all known non-African male lineages (apart from recent migrants).

A Rare Deep-Rooting D0 African Y-Chromosomal Haplogroup and Its Implications for the Expansion of Modern Humans Out of Africa

TLDR
This work resolves a long-running debate about Y-chromosomal out-of-Africa/back-to-Afrika migrations, and provides insights into the out- of-Af Africa expansion more generally.

Early human dispersals within the Americas

TLDR
Analysis of the oldest genomes suggests that there was an early split within Beringian populations, giving rise to the Northern and Southern lineages, and that the early population spread widely and rapidly suggests that their access to large portions of the hemisphere was essentially unrestricted, yet there are genomic and archaeological hints of an earlier human presence.

Tracing the Genetic Legacy of the Tibetan Empire in the Balti

TLDR
The analyses of mitochondrial DNA, Y, and X chromosome data indicated that both ancient Tibetan males and females were involved in the male-biased dispersal and the impact of Tibetan Empire on Baltistan involved dominant cultural and minor demic diffusion.

Did Indo-European Languages Stem From a Trans-Eurasian Original Language

This interdisciplinary study allowed me to establish, on the basis of linguistic, genetic, archaeological, historical and religious data, that linguistic concordances between Gaulish and Slavic were

Past successes and future opportunities for the genetics of the human Y chromosome

TLDR
The Y chromosome has a special primary role in human genetics—determining male sex—that gives it a functional unity in a way that no other chromosome has, and leads to a host of unique consequences for its medical, population and forensic genetics.

The genetic heritage of the earliest settlers persists both in Indian tribal and caste populations.

TLDR
Results show that Indian tribal and caste populations derive largely from the same genetic heritage of Pleistocene southern and western Asians and have received limited gene flow from external regions since the Holocene.

Reconstructing Indian Population History

TLDR
It is predicted that there will be an excess of recessive diseases in India, which should be possible to screen and map genetically and is higher in traditionally upper caste and Indo-European speakers.

A prehistory of Indian Y chromosomes: evaluating demic diffusion scenarios.

TLDR
The Y-chromosomal data consistently suggest a largely South Asian origin for Indian caste communities and therefore argue against any major influx, from regions north and west of India, of people associated either with the development of agriculture or the spread of the Indo-Aryan language family.

Genomic analysis of Andamanese provides insights into ancient human migration into Asia and adaptation

TLDR
The footprints of adaptive selection in the genomes of the Andamanese show that the characteristic distinctive phenotypes of this population do not reflect an ancient African origin but instead result from strong natural selection on genes related to human body size.

Genomic reconstruction of the history of extant populations of India reveals five distinct ancestral components and a complex structure

TLDR
Systematic analysis of genome-wide data on 367 unrelated individuals drawn from 18 mainland and 2 island populations selected to represent geographic, linguistic, and ethnic diversities, reveal four major ancestries in mainland India, contrary to an earlier inference of two ancestries based on limited population sampling.

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.

The Himalayas as a directional barrier to gene flow.

TLDR
The results suggest that the Tibetans and Nepalese are in part descendants of Tibeto-Burman-speaking groups originating from Northeast Asia and indicate gene flow from the Indian subcontinent and, in the case of haplogroup R, from Eurasia as well.
