Located only a short distance off the southernmost shore of the Greater Indian subcontinent, the island of Sri Lanka has long been inhabited by various ethnic populations. [] Key Result From the phylogenetic, principal coordinate and analysis of molecular variance results, the Vedda occupied a position separated from all other ethnic people of the island, who formed relatively close affiliations among themselves, suggesting a separate origin of the former.

Mitochondrial DNA (CA)n dinucleotide repeat variations in Sinhalese and Vedda populations in Sri Lanka.

TLDR
Results from this study can be used together with mitochondrial DNA information from hypervariable regions 1 and 2 to perform anthropological and forensic investigations in the two populations studied.

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.

West Eurasian mtDNA lineages in India: an insight into the spread of the Dravidian language and the origins of the caste system

TLDR
Two autochthonous subhaplogroups are identified—HV14a1 and U1a1a4, which are likely to have originated in the Dravidian-speaking populations approximately 10.5–17.9 thousand years ago (kya).

X-chromosomal STR based genetic polymorphisms and demographic history of Sri Lankan ethnicities and their relationship with global populations

TLDR
Allele frequency distribution of Indian Tamils showed subtle but statistically significant differences from those of Sinhalese and Moors, in contrast to frequency distributions previously reported for autosomal STR alleles, suggesting a sex biased demographic history among Sri Lankans requiring a separate X-STR allele frequency database for Indian Tamil.

The peopling of Lakshadweep Archipelago

TLDR
The first genetic data suggest that the majority of human ancestry in Lakshadweep is largely derived from South Asia with minor influences from East and West Eurasia.

Genetic Polymorphisms and Forensic Efficiency of 16 X-chromosomal STR Loci for Sri Lankan Population

TLDR
Allele frequency distribution of Indian Tamils showed subtle but statistically significant differences from those of Sinhalese and Moors, in contrast to frequency distributions previously reported for autosomal STR alleles, suggesting a sex biased demographic history among Sri Lankans requiring a separate X-STR allele frequency database for Indian Tamil.

Molecular analysis of HLA Class I and Class II genes in five different South Indian linguistic groups

TLDR
Comparison of HLA‐A, ‐B and ‐DRB1 allele distribution in these five linguistic groups showed that the South Indian populations were closely related to Sri Lankan populations.

Historical Tropical Forest Reliance amongst the Wanniyalaeto (Vedda) of Sri Lanka: an Isotopic Perspective

TLDR
Stable carbon and oxygen isotope data from historical Wanniyalaeto individuals from Sri Lanka are reported that suggest that while a number of individuals made use of agricultural resources in the recent past, others subsisted primarily on tropical forest resources as late as the 1800s.

Mitochondrial DNA analysis reveals diverse histories of tribal populations from India

TLDR
Analysis of the first hypervariable region of the mitochondrial DNA (mtDNA) control region in 752 individuals from 17 tribal and four nontribal groups from the Indian subcontinent suggested that caste and tribal groups are genetically similar with respect to mtDNA variation.

Inter‐ and Extra‐Indian Admixture and Genetic Diversity in Reunion Island Revealed by Analysis of Mitochondrial DNA

TLDR
Diversity, demographic and admixture analyses were performed on mtDNA variation of the Reunionese of Indian ancestry, including the Malbar and Zarab ethnic groups, in order to question their history and highlighted how ethno‐historical data are critical for reconstructing the complex history of multiethnic populations.

mtDNA variation in the South African Kung and Khwe-and their genetic relationships to other African populations.

TLDR
The mtDNA variation of 74 Khoisan-speaking individuals from Schmidtsdrift, in the Northern Cape Province of South Africa, was examined by high-resolution RFLP analysis and control region (CR) sequencing, revealing the significant substructure of macrohaplogroup L* in African populations and suggesting that the Biaka Pygmies could represent one of the oldest human populations.

Genetic relationship of Chinese ethnic populations revealed by mtDNA sequence diversity.

TLDR
Phylogenetic analysis and haplotype sharing among populations suggest that current mtDNA variation in these ethnic populations could reveal their ethnohistory to some extent, but in general, linguistic and geographic classifications of the populations did not agree well with classification by mt DNA variation.

mtDNA sequence diversity in Africa.

TLDR
The pairwise sequence distributions, patterns of coalescence events, and numbers of variable positions relative to the mean sequence difference indicate that the !Kung, Mbuti, and Biaka groups have been of constant size over time, whereas the latter have expanded in size.

Phylogeny of mitochondrial DNA macrohaplogroup N in India, based on complete sequencing: implications for the peopling of South Asia.

TLDR
It is demonstrated that the Indian mt DNA pool, even when restricted to macrohaplogroup N, harbors at least as many deepest-branching lineages as the western Eurasian mtDNA pool.

The genetic origins of the Andaman Islanders.

TLDR
The results demonstrate that Victorian anthropological collections can be used to study extinct, or seriously admixed populations, to provide new data about early human origins.

African populations and the evolution of human mitochondrial DNA.

TLDR
The African origin hypothesis of human mtDNA evolution is supported by two statistical tests and two hypervariable segments of mtDNA were sequenced from 189 people of diverse geographic origin, including 121 native Africans.
