mtDNA studies support an African origin for modern Eurasians, but expansion events within Africa have not previously been investigated. We have therefore analyzed 407 mtDNA control-region sequences from 13 African ethnic groups. A number of sequences (13%) were highly divergent and coalesced on the "mitochondrial Eve" in Africans. The remaining sequences also ultimately coalesced on this sequence but fell into four major clusters whose starlike phylogenies testify to demographic expansions. The…

Major genomic mitochondrial lineages delineate early human expansions

The relative relationships among the 42 human lineages are shown and more accurate temporal calibrations are presented than have been previously possible to give new perspectives as how modern humans spread in the Old World.

60,000 years of interactions between Central and Eastern Africa documented by major African mitochondrial haplogroup L2

Recon reconstructing the phylogeny of L2 provides insights on the complex net of within-African migrations in the last 60 thousand years, showing that lineages in Southern Africa cluster with Western/Central African lineages at a recent time scale, whereas, eastern lineages seem to be substantially more ancient.

The ancestry of Brazilian mtDNA lineages.

The mtDNA pool of present-day Brazilians clearly reflects the imprints of the early Portuguese colonization process (involving directional mating), as well as the recent immigrant waves (from Europe) of the last century.

Carriers of mitochondrial DNA macrohaplogroup L3 basal lineages migrated back to Africa from Asia around 70,000 years ago

The possibility that mtDNA macrohaplogroup L3 matured in Eurasia and returned to Africa as basal L3 lineages around 70 kya is assessed, congruent with a model proposing an out-of-Africa migration into Asia, following a northern route, of early anatomically modern humans carrying pre-L3 mtDNA lineages.

Phylogeography of mitochondrial DNA in western Europe

A cladistic notation for mitochondrial variation is described and analysis is expanded upon to present a more detailed portrait of the European mitochondrial record, suggesting that most extant mitochondrial sequences in western Europe have a local ancestry in the Early Upper Palaeolithic.

Carriers of mitochondrial DNA macrohaplogroup L3 basic lineages migrated back to Africa from Asia around 70,000 years ago

The possibility that mtDNA macrohaplogroup L3 matured in Eurasia and returned to Africa as basic L3 lineages around 70 kya is assessed, congruent with a model proposing an out-of-Africa of early anatomically modern humans around 125 kya.

African human mtDNA phylogeography at-a-glance.

The mitochondrial DNA (mtDNA) genetic system has long proven to be useful for studying the demographic history of our species, since their proposed Southeast/East African origin 200 kya. Despite the

The making of the African mtDNA landscape.

The results suggest that the southeast Bantu speakers have a composite origin on the maternal line of descent, with approximately 44% of lineages deriving from West Africa, approximately 21% from either West or Central Africa, Approximately 30% from East Africa, and approximately 5% from southern African Khoisan-speaking groups.



Mismatch distributions of mtDNA reveal recent human population expansions.

Restriction fragment length polymorphism (RFLP) and DNA sequence analyses of human mitochondrial DNAs (mtDNAs) indicate that significant expansions occurred during the late Middle and Upper Paleolithic in 23 of the 25 populations examined.

Eighty-eight types of mitochondrial DNA were found by sequencing the most variable part of the control region from 117 Caucasians, implying that the probability of survival of new lineages has undergone dramatic changes, probably due to population expansion.

Demographic history of India and mtDNA-sequence diversity.

The demographic history of India was examined by comparing mtDNA sequences obtained from members of three culturally divergent Indian subpopulations (endogamous caste groups). While an inferred tree

Origin and evolution of Native American mtDNA variation: a reappraisal.

Reappraising mtDNA control region sequences from aboriginal Siberians and Native Americans confirms in agreement with linguistic, archaeological and climatic evidence that the major wave of migration brought one population, ancestral to the Amerinds, from northeastern Siberia to America 20,000-25,000 years ago.

Origin and differentiation of human mitochondrial DNA.

The distribution of shared types between continental groups indicates that caucasoid populations could be the closest to an ancestral population from which all other continental groups would have diverged and the lapse of time necessary for creating the observed molecular diversity from an ancestral monomorphic population has been calculated.

From Asia to Europe: mitochondrial DNA sequence variability in Bulgarians and Turks

Mean pairwise differences suggest that a demographic expansion occurred sequentially in the Middle East, through Turkey, to the rest of Europe (Bulgaria included), and would correspond to the arrival of anatomically modern humans in Europe.

Minisatellite diversity supports a recent African origin for modern humans

The data strongly support a recent African origin for modern human diversity at this locus, and give an unusually detailed view of the different allelic structures represented on modern human chromosomes.

Recent African origin of modern humans revealed by complete sequences of hominoid mitochondrial DNAs.

The shallow ancestry of human mtDNAs, together with the observation that the African sequence is the most diverged among humans, strongly supports the recent African origin of modern humans, Homo sapiens sapiens.

Mitochondrial DNA and human evolution

All these mitochondrial DMAs stem from one woman who is postulated to have lived about 200,000 years ago, probably in Africa, implying that each area was colonised repeatedly.
