Genetic variation patterns of β-thalassemia in Western Andalusia (Spain) reveal a structure of specific mutations within the Iberian Peninsula
The long history of endemic malaria in the study territory, the rather high consanguinity rates among its autochthonous population, and other demographic features have been used here to understand the western Andalusian β-thalassemia molecular portrait
Genetic Structure of the Western and Eastern African Sahel/Savannah Belt and the Role of Nomadic Pastoralists as Inferred from the Variation of D-Loop Mitochondrial DNA Sequences
The objective of this study was to provide deeper knowledge of the maternal genetic structure and demographic history of the human populations of the Sahel/Savannah belt, the extensive region lying between the Sahara and tropical rainforests, spanning from the Atlantic Ocean to the Red Sea coast. The study aimed to confijirm or disconfijirm archaeological and linguistic data indicating that the region’s populations underwent diversifijication as …

The objective of this study was to provide deeper knowledge of the maternal genetic structure and demographic history of the human populations of the Sahel/Savannah belt, the extensive region lying between the Sahara and tropical rainforests, spanning from the Atlantic Ocean to the Red Sea coast.

Internal diversification of non‐Sub‐Saharan haplogroups in Sahelian populations and the spread of pastoralism beyond the Sahara
BACKGROUND: Today, African pastoralists are found mainly in the Sahel/Savannah belt spanning 6,000 km from west to east, flanked by the Sahara to the north and tropical rainforests to the south. The most significant group among them are the Fulani who not only keep cattle breeds of possible West Eurasian ancestry, but form themselves a gene pool containing some paternally and maternally-transmitted West Eurasian haplogroups. MATERIALS AND METHODS…
Radiocarbon Dating the Beginning of the Neolithic in Iberia
Radiocarbon dating of samples of charred cereal, biomolecularly confirmed sheep bone, human bone from burials, and diagnostic artifacts places the appearance of the ‘Neolithic package’ in Iberia ca. 5500 Cal BC. The earliest dates are statistically indistinguishable from Catalonia to Portugal and, whenever their archaeological context is secure, the associated pottery includes a significant, if not majority cardial-decorated component. These patt…
Archaeogenetics of Africa and of the African Hunter-Gatherers
The Expansion of mtDNA Haplogroup L3 within and out of Africa
Although fossil remains show that anatomically modern humans dispersed out of Africa into the Near East ∼100 to 130 ka, genetic evidence from extant populations has suggested that non-Africans descend primarily from a single successful later migration. Within the human mitochondrial DNA (mtDNA) tree, haplogroup L3 encompasses not only many sub-Saharan Africans but also all ancient non-African lineages, and its age therefore provides an upper boun…
Pleistocene‐Holocene boundary in Southern Arabia from the perspective of human mtDNA variation
It is now known that several population movements have taken place at different times throughout southern Arabian prehistory. One of the principal questions under debate is if the Early Holocene peopling of southern Arabia was mainly due to input from the Levant during the Pre‐Pottery Neolithic B, to the expansion of an autochthonous population, or some combination of these demographic processes. Since previous genetic studies have not been able …
Population history of the Red Sea—genetic exchanges between the Arabian Peninsula and East Africa signaled in the mitochondrial DNA HV1 haplogroup
Archaeological studies have revealed cultural connections between the two sides of the Red Sea dating to prehistory. The issue has still not been properly addressed, however, by archaeogenetics. We focus our attention here on the mitochondrial haplogroup HV1 that is present in both the Arabian Peninsula and East Africa. The internal variation of 38 complete mitochondrial DNA sequences (20 of them presented here for the first time) affiliated into…
Post‐last glacial maximum expansion from Iberia to North Africa revealed by fine characterization of mtDNA H haplogroup in Tunisia
The first large‐scale fine characterization of Tunisian H lineages clarifies that the post‐Last glacial maximum expansion originating in Iberia not only led to the resettlement of Europe but also of North Africa. We found that 46% of 81 Tunisian H lineages subscreened for 1,580 bp in mtDNA coding region were affiliated with H1 and H3 subhaplogroups, which are known to have originated in Iberia. Although no signs of local expansion were detected, …
Out of Arabia—The settlement of Island Soqotra as revealed by mitochondrial and Y chromosome genetic diversity
The Soqotra archipelago is one of the most isolated landmasses in the world, situated at the mouth of the Gulf of Aden between the Horn of Africa and southern Arabia. The main island of Soqotra lies not far from the proposed southern migration route of anatomically modern humans out of Africa ∼60,000 years ago (kya), suggesting the island may harbor traces of that first dispersal. Nothing is known about the timing and origin of the first Soqotri …
Near Eastern Neolithic genetic input in a small oasis of the Egyptian Western Desert
The Egyptian Western Desert lies on an important geographic intersection between Africa and Asia. Genetic diversity of this region has been shaped, in part, by climatic changes in the Late Pleistocene and Holocene epochs marked by oscillating humid and arid periods. We present here a whole genome analysis of mitochondrial DNA (mtDNA) and high‐resolution molecular analysis of nonrecombining Y‐chromosomal (NRY) gene pools of a demographically small…
Regional differences in the distribution of the sub‐Saharan, West Eurasian, and South Asian mtDNA lineages in Yemen
Despite its key location for population movements out of and back into Africa, Yemen has not yet been sampled on a regional level for an investigation of sub‐Saharan, West Eurasian, and South Asian genetic contributions. In this study, we present mitochondrial DNA (mtDNA) data for regionally distinct Yemeni populations that reveal different distributions of mtDNA lineages. An extensive database of mtDNA sequences from North and East African, Midd…
Islands Inside an Island
Jerba Island, located in South Eastern Tunisia, is inhabited by four ethnic groups: Berbers, Arabs, sub‐Saharans, and Jews. All live in distinct areas, although the Arabs are also distributed all over the island. The first Arab settlement was founded in the 7th century A.D., so co‐existence with Berbers has lasted for more than a millennium. Religious and cultural differences have represented an obstacle to the intermixing of these groups, and am…
Female Gene Pools of Berber and Arab Neighboring Communities in Central Tunisia
North African populations are considered genetically closer to Eurasians than to sub-Saharans. However, they display a considerably high mtDNA heterogeneity among them, namely in the frequencies of the U6, East African, and sub-Saharan haplogroups. In this study, we describe and compare the female gene pools of two neighboring Tunisian populations, Kesra (Berber) and Zriba (non-Berber), which have contrasting historical backgrounds. Both populati…
African Female Heritage in Iberia
The Iberian peninsula is a peripheral region of Europe in close proximity to Africa. Its inhabitants have an overall mtDNA genetic landscape typical of European background, although with signs of some African influence, whose features we deemed to disclose by analyzing available mtDNA HVRI distributions and new data. We analyzed 1,045 sequences. The most relevant results are the following: (1) North African sequences (haplogroup U6) present an ov…
