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.
Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.
TLDR
These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift.
Upper Palaeolithic Siberian genome reveals dual ancestry of Native Americans
TLDR
The findings reveal that western Eurasian genetic signatures in modern-day Native Americans derive not only from post-Columbian admixture, as commonly thought, but also from a mixed ancestry of the First Americans.
Phylogeography of Y-chromosome haplogroup I reveals distinct domains of prehistoric gene flow in europe.
TLDR
Haplogroup I, the only major clade of the Y phylogeny that is widespread over Europe but virtually absent elsewhere, is analyzed, in detail, and it is revealed that it underwent a postglacial expansion and marked the human colonization of Sardinia approximately 9,000 years ago.
The genome-wide structure of the Jewish people
TLDR
High-density bead arrays to genotype individuals from 14 Jewish Diaspora communities are used to compare patterns of genome-wide diversity with those from 69 Old World non-Jewish populations, of which 25 have not previously been reported.
New insights into the Tyrolean Iceman's origin and phenotype as inferred by whole-genome sequencing.
TLDR
The complete genome sequence of the Iceman is reported and 100% concordance between the previously reported mitochondrial genome sequence and the consensus sequence generated from the genomic data is shown.
A recent bottleneck of Y chromosome diversity coincides with a global change in culture.
TLDR
A study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples, infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky, and hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.
The western and eastern roots of the Saami--the story of genetic "outliers" told by mitochondrial DNA and Y chromosomes.
TLDR
A high-resolution phylogenetic analysis of Saami genetic heritage was undertaken in a comprehensive context, through use of maternally inherited mitochondrial DNA (mtDNA) and paternALLY inherited Y-chromosomal variation, and it was shown that the "Saami motif" variant of mtDNA haplogroup U5b is present in a large area outside Scandinavia.
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.
High-resolution phylogenetic analysis of southeastern Europe traces major episodes of paternal gene flow among Slavic populations.
TLDR
The extent and nature of southeastern Europe (SEE) paternal genetic contribution to the European genetic landscape were explored based on a high-resolution Y chromosome analysis involving 681 males from seven populations in the region, finding that five major haplogroups comprise more than 70% of SEE total genetic variation.
