“…The pastoralist nature of the groups involved in the dispersion of haplogroup R1b1a in Central Africa is also supported by the V88 distribution as well as by the distribution of its subclade V69 (the only one found in the African continent). 7 In fact, although the origin and dispersion of these lineages seem to be much older than the beginning of the Bantu expansion, which began in this same region in Central Africa, 44,45 its frequency decreases drastically towards the South.…”

Human Y chromosomes belonging to the haplogroup R1b1-P25, although very common in Europe, are usually rare in Africa. However, recently published studies have reported high frequencies of this haplogroup in the central-western region of the African continent and proposed that this represents a 'back-to-Africa' migration during prehistoric times. To obtain a deeper insight into the history of these lineages, we characterised the paternal genetic background of a population in Equatorial Guinea, a Central-West African country located near the region in which the highest frequencies of the R1b1 haplogroup in Africa have been found to date. In our sample, the large majority (78.6%) of the sequences belong to subclades in haplogroup E, which are the most frequent in Bantu groups. However, the frequency of the R1b1 haplogroup in our sample (17.0%) was higher than that previously observed for the majority of the African continent. Of these R1b1 samples, nine are defined by the V88 marker, which was recently discovered in Africa. As high microsatellite variance was found inside this haplogroup in Central-West Africa and a decrease in this variance was observed towards Northeast Africa, our findings do not support the previously hypothesised movement of Chadic-speaking people from the North across the Sahara as the explanation for these R1b1 lineages in Central-West Africa. The present findings are also compatible with an origin of the V88-derived allele in the Central-West Africa, and its presence in North Africa may be better explained as the result of a migration from the south during the mid-Holocene.

“…The Western Cape Province of South Africa has a rich genetic history, arising from many parts of the world including the local ancient Khoisan population [8][9][10][11] , the greater Bantu groups from the Niger-Congo phylum 12,[14][15][16] , European settlers 17,18 and slaves from the East 18,19 . Marriages amongst the different population groups were once common 17,20 , and produced a heterogeneous new and genetically unique population in the Western Cape, until apartheid was introduced and resulted in a drastic decrease in cross-population gene flow 6,20,25 .…”

“…12,13 Variants from this Bantu family in the south included the Nguni group (Xhosa, Zulu, Swati and Ndebele tribes) and the Southern (also called the Sotho-Tswana) groups (Southern Sotho, Northern Sotho, Tswana, Venda and Tsonga tribes). 12,14,15 The Nguni populations migrated southwards over many centuries with large herds of Nguni cattle. These migration patterns started around 2000 years ago followed by larger migration impressions around 1400 CE.…”

The Kirsten Skeletal Collection is curated in the Division of Anatomy and Histology, Faculty of Medicine and Health Sciences, Stellenbosch University, South Africa. It comprises the largest documented cadaver-derived South African coloured skeletal collection in the world. Our aim in this paper is to present an inventory and characterise the identified skeletons in the Kirsten Skeletal Collection as well as provide a descriptive indication of what researchers can expect to encounter at the anthropology unit at Stellenbosch University. The skeletal material was derived mainly from the cadaver donation programme of the Division of Anatomy and Histology over a 58-year period (1957–2015). All pertinent information for each individual skeleton is entered into a database and a full skeletal inventory is established. The skeletal database registry was analysed to demonstrate the distribution of age, sex and population affinity of individuals in the collection. Currently, this collection consists of 1161 skeletons with known records. Despite differences in the age and sex composition, the skeletal profile in general reflects mainly the profile of the Western Cape population. Most individuals were born between 1920 and 1950, placing the Kirsten Skeletal Collection in the early to mid-20th century. The age at death for the greatest proportion (41.8%) of individuals was between 40 and 60 years. Current biological profile techniques in age, ancestry and sex estimation can be improved and, among others, new regional and ancestral specific standards for the biologically unique and diverse South African coloured population can be developed.

“…Within Africa, a number of mtDNA lineages have been associated with various stages of the Bantu dispersals, including subsets of L0a Watson et al 1997), L1c (Batini et al 2007;Salas et al 2002), L2a Salas et al 2002), L3b (Salas et al 2002;Soares et al 2012;Watson et al 1997) and L3e (Bandelt et al 2001;Pereira et al 2001;Plaza et al 2004;Salas et al 2002;Soares et al 2012). Many of these are inferred to have spread from West-Central Africa, although some, e.g.…”

Mosaic maternal ancestry in the Great Lakes region of East Africa

The Great Lakes lie within a region of East Africa with very high human genetic diversity, home of many ethno-linguistic groups usually assumed to be the product of a small number of major dispersals. However, our knowledge of these dispersals relies primarily on the inferences of historical linguistics and oral traditions, with attempts to match up the archaeological evidence where possible. This is an obvious area to which archaeogenetics can contribute, yet Uganda, at the heart of these developments, has not been studied for mitochondrial DNA (mtDNA) variation. Here, we compare mtDNA lineages at this putative genetic crossroads across 409 representatives of the major language groups: Bantu speakers and Eastern and Western Nilotic speakers. We show that Uganda harbours one of the highest mtDNA diversities within and between linguistic groups, with the various groups significantly differentiated from each other. Despite an inferred linguistic origin in South Sudan, the data from the two Nilotic-speaking groups point to a much more complex history, involving not only possible dispersals from Sudan and the Horn but also large-scale assimilation of autochthonous lineages within East Africa and even Uganda itself. The Eastern Nilotic group also carries signals characteristic of West-Central Africa, primarily due to Bantu influence, whereas a much stronger signal in the Western Nilotic group suggests direct West-Central African ancestry. Bantu speakers share lineages with both Nilotic groups, and also harbour East African lineages not found in Western Nilotic speakers, likely due to assimilating indigenous populations since arriving in the region ~3000 years ago.
