Anatomically modern humans originated in Africa around 200 thousand years ago (ka)1–4. Although some of the oldest skeletal remains suggest an eastern African origin2, southern Africa is home to contemporary populations that represent the earliest branch of human genetic phylogeny5,6. Here we generate, to our knowledge, the largest resource for the poorly represented and deepest-rooting maternal L0 mitochondrial DNA branch (198 new mitogenomes for a total of 1,217 mitogenomes) from contemporary… 

Evaluating refugia in recent human evolution in Africa

Homo sapiens have adapted to an incredible diversity of habitats around the globe. This capacity to adapt to different landscapes is clearly expressed within Africa, with Late Pleistocene Homo

The archeological record documents human presence in the Kalahari Basin from the Early Pleistocene onwards, and the region is not abandoned during glacial phases, which adds support to poly‐centric, pan‐African models for the emergence of the authors' species.

Searching for the roots of the first free African American community

The results confirmed the strong isolation of the Palenque, with some degree of influx of Native American maternal lineages, and a European admixture exclusively mediated by men.

Human origins in Southern African palaeo-wetlands? Strong claims from weak evidence

The authors surprisingly disregard recent evidence and debate on human origins in Africa and infer that ‘anatomically modern humans’ originated in the Makgadikgadi–Okavango palaeo-wetland of southern Africa around 200 thousand years ago.

Climate effects on archaic human habitats and species successions

It has long been believed that climate shifts during the last 2 million years had a pivotal role in the evolution of our genus Homo1–3. However, given the limited number of representative

Study of human origin and migration from a novel genomic footprint derived from mitochondrial sequences

The existence of the archaic human at 4-5 million years ago and presence of human in Africa at 800 kilo years ago is roughly estimated and some close relationships between the modern Asians and the archaic humans along with the Africans are shown.

Human origin and migration deciphered from a novel genomic footprints of mitochondrial sequences

This study roughly estimates the existence of the archaic human at 800-900 kilo years ago and presence of human in Africa at 600-700 kiloyears ago, and proposes a new method to derive the bootstrap replica from the genome sequences by considering the genetic variance to demonstrate the robustness of the obtained trees.

Human Populations: Origins and Evolution

Findings from analyses of genomic diversity support an African origin of the authors' species, followed by dispersal of rather small groups of people in the other continents, and models of genetic replacement of archaic human forms by anatomically modern humans account for current diversity better than any alternative models.



First Ancient Mitochondrial Human Genome from a Prepastoralist Southern African

Providing the first genomic evidence that prepastoral Southern African marine foragers carried the earliest diverged maternal modern human lineages, this study emphasizes the significance of Southern African archeological remains in defining early modern human origins.

The First Modern Human Dispersals across Africa

It is proposed that the last common ancestor of modern human mtDNAs possibly arose in central Africa ~180 ka, at a time of low population size, and may have been responsible for the spread of southern click-consonant languages to eastern Africa, contrary to the view that these eastern examples constitute relicts of an ancient, much wider distribution.

A dispersal of Homo sapiens from southern to eastern Africa immediately preceded the out-of-Africa migration

A mitochondrial signal of such a dispersal soon after ~70 ka is identified – the only time in the last 200,000 years that humid climate conditions encompassed southern and tropical Africa.

The Expansion of mtDNA Haplogroup L3 within and out of Africa.

The similarity of the age of L3 to its two non-African daughter haplogroups, M and N, suggests that the same process was likely responsible for both the L3 expansion in Eastern Africa and the dispersal of a small group of modern humans out of Africa to settle the rest of the world.

Near eastern neolithic genetic input in a small oasis of the Egyptian Western Desert.

The whole genome sequencing strategy and molecular dating allowed us to detect the accumulation of local mtDNA diversity to 5,138 +/- 3,633 YBP, and theY-chromosome gene pool reveals high frequencies of the Near Eastern J1 and the North African E1b1b 1b lineages, both generally known to have expanded within North Africa during the Neolithic.

Mapping human dispersals into the Horn of Africa from Arabian Ice Age refugia using mitogenomes

The presence of R0a in Southwest Arabia in the Holocene at the nexus of a trading network that developed after ~3 ka between Africa and the Indian Ocean led to some gene flow even further afield, into Iran, Pakistan and India.

The dawn of human matrilineal diversity.

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.

A climatic context for the out-of-Africa migration

Around 200,000 yr ago, Homo sapiens emerged in Africa. By 40 ka, Homo sapiens had spread throughout Eurasia, and a major competing species, the Neanderthals, became extinct. The factors that drove
