Abstract The large scale spread of Bantu-speaking populations remains one of the most debated questions in African population history. In this work we studied the genetic structure of 19 Bantu-speaking groups from Mozambique and Angola using a multilocus approach based on 14 newly developed compound haplotype systems (UEPSTRs), each consisting of a rapidly evolving short tandem repeat (STR) closely linked to a unique event polymorphism (UEP). We compared the ability of UEPs, STRs and UEPSTRs… Expand
Mozambican genetic variation provides new insights into the Bantu expansion
TLDR
The results provide the first genetic evidence in support of a rapid North-South dispersal of Bantu peoples along the Indian Ocean Coast, as inferred from the distribution and antiquity of Early Iron Age assemblages associated with the Kwale archaeological tradition. Expand
At the southeast fringe of the Bantu expansion: genetic diversity and phylogenetic relationships to other sub-Saharan tribes
TLDR
Findings indicate that, in addition to a shared linguistic, cultural and genetic heritage, geography may have impacted the paternal landscape of sub-Saharan Africa, the admixture and assimilation processes of Bantu elements were both highly complex and region-specific. Expand
Mitochondrial DNA diversity in two ethnic groups in southeastern Kenya: perspectives from the northeastern periphery of the Bantu expansion.
TLDR
Analysis of mtDNA hypervariable region I variation in 352 individuals from the Taita and Mijikenda ethnic groups was analyzed and suggested a more complex demographic history where the nature of Bantu and non-Bantu interactions varied throughout the area. Expand
Along the Indian Ocean Coast: Genomic Variation in Mozambique Provides New Insights into the Bantu Expansion
TLDR
The results provide the first genetic evidence in support of a rapid North–South dispersal of Bantu peoples along the Indian Ocean Coast, as inferred from the distribution and antiquity of Early Iron Age assemblages associated with the Kwale archaeological tradition. Expand
An early divergence of KhoeSan ancestors from those of other modern humans is supported by an ABC-based analysis of autosomal resequencing data.
TLDR
Substantial support is found for a model of an early divergence of KhoeSan ancestors from a proto-Pygmy-non- Pygmy NKs group ∼110 thousand years ago over a model incorporating a proto-' proto-KhoeSan-pygmy hunter-gatherer divergence from the ancestors of non- pygmyNKs. Expand
Genetic variation reveals large-scale population expansion and migration during the expansion of Bantu-speaking peoples
TLDR
This study re-analysed microsatellite markers typed for large number of African populations that—owing to their fast mutation rates—capture signatures of recent population history and demonstrates that west African groups rapidly expanded both in numbers and over a large geographical area, affirming the fact that the Bantu expansion was one of the most dramatic demographic events in human history.

Genetics and demographic history of the Bantu
Peoples speaking languages of the Bantu family are widespread in sub-Saharan Africa, from the equatorial rainforest to the Cape of Good Hope. Their present-day distribution is the result of aExpand
Migration and interaction in a contact zone: mtDNA variation among Bantu-speakers in southern Africa
TLDR
This study analyzes complete mtDNA genome sequences from over 900 Bantu-speaking individuals from Angola, Zambia, Namibia, and Botswana to investigate the demographic processes at play during the last stages of the BantU expansion. Expand
Migration and Interaction in a Contact Zone: mtDNA Variation among Bantu-Speakers in Southern Africa
TLDR
This study analyzes complete mtDNA genome sequences from over 900 Bantu-speaking individuals from Angola, Zambia, Namibia, and Botswana to investigate the demographic processes at play during the last stages of the BantU expansion. Expand
Studying the evolutionary history of single markers and the demographic history of African populations: The evolution of lactase persistence; Genetic structure of Bantu-speaking populations, and the microevolutionary impact of the Atlantic slave trade
TLDR
This study shows that a limited number of microsatellite loci may provide sufficient resolution to reconstruct key aspects of the evolutionary history of lactase persistence, providing an alternative to approaches based on large numbers of SNPs. Expand

mtDNA variability in two Bantu-speaking populations (Shona and Hutu) from Eastern Africa: implications for peopling and migration patterns in sub-Saharan Africa.
TLDR
The results indicate that the Shona and Hutu are closely related to the other Bantu-speaking populations, however, there are some differences in haplogroup composition between the two populations, mainly due to different genetic contributions from neighboring populations. Expand
On the edge of Bantu expansions: mtDNA, Y chromosome and lactase persistence genetic variation in southwestern Angola
TLDR
Genetic variation in southwestern Angola essentially results from the encounter of an offshoot of West-Central Africa with autochthonous Khoisan-speaking peoples from the south. Expand
Bantu and European Y-lineages in Sub-Saharan Africa.
TLDR
Haplotype matching performed for Y-STR haplotypes in several sub-Saharan populations allowed the confirmation of a putative founder haplotype, and its one-step neighbours, of Bantu origin, and detected an increasing drift towards the south, with a stronger reduction of diversity along the western coast. Expand
Origins and Genetic Diversity of Pygmy Hunter-Gatherers from Western Central Africa
TLDR
The results show that recent isolation, genetic drift, and heterogeneous admixture enabled a rapid and substantial genetic differentiation among Western Central African pygmies, consistent with the various sociocultural behaviors related to intermariages between pygmie and nonpygmies. Expand
Coevolution of languages and genes on the island of Sumba, eastern Indonesia
TLDR
A model to explain linguistic and demographic coevolution at fine spatial and temporal scales is proposed and a positive correlation was found between the percentage of Y chromosome lineages that derive from Austronesian (as opposed to aboriginal) ancestors and the retention of PAn cognates. Expand
The making of the African mtDNA landscape.
TLDR
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.

Inferring the Demographic History of African Farmers and Pygmy Hunter–Gatherers Using a Multilocus Resequencing Data Set
TLDR
The branching history of Pygmy hunter–gatherers and agricultural populations from Africa and estimated separation times and gene flow between these populations are studied to increase knowledge of the history of the peopling of the African continent in a region lacking archaeological data. Expand
The Genetic Structure and History of Africans and African Americans
TLDR
A detailed genetic analysis of most major groups of African populations is provided, suggesting that Africans represent 14 ancestral populations that correlate with self-described ethnicity and shared cultural and/or linguistic properties. Expand
Using nuclear haplotypes with microsatellites to study gene flow between recently separated Cichlid species
TLDR
The analysis suggests that Cichlid fishes from Lake Malawi have been exchanging genes since the time they began to diverge, and an empirical protocol for using loci that include unique nuclear DNA sequence haplotypes together with linked microsatellites or short tandem repeats (STRs). Expand
