Tracing European founder lineages in the Near Eastern mtDNA pool.
TLDR
There has been substantial back-migration into the Near East, there was a founder effect or bottleneck associated with the Last Glacial Maximum, 20,000 years ago, and a way to account for multiple dispersals of common sequence types is suggested.
The Simons Genome Diversity Project: 300 genomes from 142 diverse populations
TLDR
It is demonstrated that indigenous Australians, New Guineans and Andamanese do not derive substantial ancestry from an early dispersal of modern humans; instead, their modern human ancestry is consistent with coming from the same source as that of other non-Africans.
Beringian Standstill and Spread of Native American Founders
TLDR
The newly resolved phylogenetic structure suggests that ancestors of Native Americans paused when they reached Beringia, during which time New World founder lineages differentiated from their Asian sister-clades, and a swift migration southward that distributed the founder types all the way to South America.
Ancient human genomes suggest three ancestral populations for present-day Europeans
TLDR
It is shown that the great majority of present-day Europeans derive from at least three highly differentiated populations: West European Hunter-Gatherers (WHG), who contributed ancestry to all Europeans but not to Near Easterners; Ancient North Eurasians (ANE); and Early European Farmers (EEF), who were mainly of Near Eastern origin but also harbored WHG-related ancestry.
Deep common ancestry of Indian and western-Eurasian mitochondrial DNA lineages
TLDR
An extensive deep late Pleistocene genetic link between contemporary Europeans and Indians is found, provided by the mtDNA haplogroup U, which encompasses roughly a fifth of mtDNA lineages of both populations.
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.
The emerging limbs and twigs of the East Asian mtDNA tree.
TLDR
The phylogenetic backbone of the East Asian mtDNA tree is determined by using published complete mtDNA sequences and assessing both coding and control region variation in 69 Han individuals from southern China, confirming that the East Asia mtDNA pool is locally region-specific and completely covered by the two superhaplogroups M and N.
Erratum to: Most of the extant mtDNA boundaries in South and Southwest Asia were likely shaped during the initial settlement of Eurasia by anatomically modern humans
TLDR
Analysis of the mtDNA haplogroups, which are shared between Indian and Iranian populations and exhibit coalescence ages corresponding to around the early Upper Paleolithic, indicates that they are present in India largely as Indian-specific sub-lineages.
A "Copernican" reassessment of the human mitochondrial DNA tree from its root.
TLDR
This "Copernican" reassessment of the human mtDNA tree from its deepest root should resolve previous problems and will have a substantial practical and educational influence on the scientific and public perception of human evolution by clarifying the core principles of common ancestry for extant descendants.
Ethiopian mitochondrial DNA heritage: tracking gene flow across and around the gate of tears.
TLDR
Phylogeographic identification of potential founder haplotypes revealed that approximately one-half of haplogroup L0-L5 lineages in Yemenis have close or matching counterparts in southeastern Africans, compared with a minor share in Ethiopians.
