The origin and dispersal of Y‐Chromosomal haplogroup O2a1‐M95, distributed across the Austro Asiatic speaking belt of East and South Asia, are yet to be fully understood. Various studies have suggested either an East Indian or Southeast Asian origin of O2a1‐M95. We addressed the issue of antiquity and dispersal of O2a1‐M95 by sampling 8748 men from India, Laos, and China and compared them to 3307 samples from other intervening regions taken from the literature. Analyses of haplogroup frequency… 
Y-chromosome diversity suggests southern origin and Paleolithic backwave migration of Austro-Asiatic speakers from eastern Asia to the Indian subcontinent
TLDR
It is demonstrated that the O2a1-M95 lineage originated in the southern East Asia among the Daic-speaking populations ~20–40 thousand years ago and then dispersed southward to Southeast Asia after the Last Glacial Maximum before moving westward to the Indian subcontinent.
Uniparental Genetic Analyses Reveal the Major Origin of Fujian Tanka from Ancient Indigenous Daic Populations
TLDR
The interpopulation comparison revealed that the Fujian Tanka have a closer affinity with Daic populations than with Han Chinese in paternal lineages but are closely clustered with southern Han populations such as Hakka and Chaoshanese in maternal lineages.
The genetic legacy of continental scale admixture in Indian Austroasiatic speakers
TLDR
Using genome-wide genotype data of 102 Munda speakers and contextual data from South and Southeast Asia, admixture dates between 2000–3800 years ago for different populations of Munda are retrieved and the grouping of the MundA speakers into North and South Munda based on linguistics is in concordance with genome- wide data.
The forensic landscape and the population genetic analyses of Hainan Li based on massively parallel sequencing DNA profiling
TLDR
The phylogenetic analyses indicated that Hainan Li, with a southern East Asia origin and Tai-Kadai language-speaking language, is an isolated population relatively.
Paternal heritage of the Han Chinese in Henan province (Central China): high diversity and evidence of in situ Neolithic expansions
TLDR
It is suggested that the high genetic diversity in the paternal gene pool of modern Han populations is mainly attributed to the reservation of a larger number of lineages that diverged in the Palaeolithic Age, while the recent expansion of limited lineages contributed to the majority of the gene Pool ofmodern Han populations.

Forensic characteristics and phylogenetic analyses of one branch of Tai‐Kadai language‐speaking Hainan Hlai (Ha Hlai) via 23 autosomal STRs included in the Huaxia™ Platinum System
Hainan Island, located in the South China Sea and separated from the Leizhou Peninsula by Qiongzhou Strait, is the second largest island after Taiwan in China. With the expansion of Han Chinese and
The Munda Maritime Hypothesis
On the basis of historical linguistic and language geographic evidence, the authors advance the novel hypothesis that the Munda languages originated on the east coast of India after their

An Updated Phylogeny of the Human Y-Chromosome Lineage O2a-M95 with Novel SNPs
TLDR
An updated phylogeny of the O2a-M95 lineage is characterized, which improves the resolution of this lineage, and allows for greater tracing of the prehistory of human populations in eastern Asia and the Pacific, which may yield novel insights into the patterns of language diversification and population movement in these regions.
A major Y-chromosome haplogroup R1b Holocene era founder effect in Central and Western Europe
TLDR
Within the M412 dichotomy, the major S116 sub-clade shows a frequency peak in the upper Danube basin and Paris area with declining frequency toward Italy, Iberia, Southern France and British Isles, and more complex pre-Neolithic scenarios remain possible for the L23(xM412) components in Southeast Europe and elsewhere.
Genetic Imprints of Pleistocene Origin of Indian Populations: A Comprehensive Phylogeographic Sketch of Indian Y-Chromosomes
TLDR
It is proposed that the present day Dravidian speaking populations of South India are the descendants of earliest Pleistocene settlers while Austro-Asiatic speakers came from SE Asia in a later migration event.
Origin, diffusion, and differentiation of Y-chromosome haplogroups E and J: inferences on the neolithization of Europe and later migratory events in the Mediterranean area.
TLDR
The phylogeography of Y-chromosome haplogroups E and J was investigated in >2400 subjects from 29 populations, mainly from Europe and the Mediterranean area but also from Africa and Asia, revealing spatial patterns that are consistent with a Levantine/Anatolian dispersal route to southeastern Europe.
The peopling of Europe and the cautionary tale of Y chromosome lineage R-M269
TLDR
Analysis of frequency patterns and diversity in the largest collection of R-M269-related chromosomes yet assembled reveals no geographical trends in diversity, in contradiction to expectation under the Neolithic hypothesis, and suggests an alternative explanation for the apparent cline in diversity recently described.
Human Migration through Bottlenecks from Southeast Asia into East Asia during Last Glacial Maximum Revealed by Y Chromosomes
Molecular anthropological studies of the populations in and around East Asia have resulted in the discovery that most of the Y-chromosome lineages of East Asians came from Southeast Asia. However,
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.
Population genetic structure in Indian Austroasiatic speakers: the role of landscape barriers and sex-specific admixture.
TLDR
It is proposed that AA speakers in India today are derived from dispersal from southeast Asia, followed by extensive sex-specific admixture with local Indian populations, strongly supporting the first of the two hypotheses.
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.
Major east-west division underlies Y chromosome stratification across Indonesia.
TLDR
A four-phase colonization model is put forward in which Paleolithic migrations of hunter-gatherers shape the primary structure of current Indonesian Y chromosome diversity, and Neolithic incursions make only a minor impact on the paternal gene pool, despite the large cultural impact of the Austronesian expansion.
