There are complications in relating admixture sources to contemporary populations. We also stress that the use of Khoesan in the current setting refers to groups with shared linguistic characteristics which does not necessarily imply shared close genealogical relationships (Güldemann and Fehn, 2014). For example, multiple ethnic groups from The Gambia and Mali all show signs of sharing the same set of ancestors from West Africa, Europe and Asia who mixed around 2000 years ago. We outline the details of this analysis below, but note here that, because this approach is based on the comparison and analysis of painted chromosomes, it offers a different perspective from approaches based on comparisons of allele frequencies. This shift was long and complex and occurred at different speeds, instigating contrasting interactions between the agriculturalist pioneers and the inhabitant people (Mitchell, 2002; Marks et al., 2014). We determined the regional identity of the two populations used to generate Cm⁢a⁢x. It is important to note that dates of admixture inferred through genetics will always be more recent than the date at which two populations have come together. 12) More generally, the manuscript is a bit too long; in particular, the Discussion and Abstract contain a substantial amount of content on genetic epidemiology and infectious disease that is only tangentially related to the analyses performed in the manuscript. Abstract (emphasis mine): In the last three decades, genetic studies have played an increasingly important role in exploring human history. Recall that for GLOBETROTTER analyses two painting steps are required. (2013) demonstrated that this theory holds even when using the admixed population itself as one of the reference populations. To summarise these events, we show the composition of the admixing source groups as barplots for each population coloured by the contribution from each African ancestry region and Eurasia, alongside the inferred date (with confidence interval determined by bootstrapping) and the estimated proportion of admixture (Figure 4). First, we used the classical measure FST (Hudson et al., 1992; Bhatia et al., 2013) which measures the differentiation in SNP allele frequencies between two groups. For each event in each ethnic group we show the largest inferred amplitude and date of an admixture event involving two reference populations (Pop1 and Pop2). Standard errors are computed using a block jackknife procedure in blocks of 500 SNPs (Supplementary file 2). In the central panel, for each source, we highlight the ancestry regions providing curves that are not significantly different from the best curves. To describe this more concisely, we now write: “The current dataset does not cover all of Africa. These observations are specific to groups in our analysis, and cannot be extended to other groups from similar populations; the seven ethnic groups from The Gambia were all collected in and around Banjul in the Western District, whereas the three ethnic groups from Ghana were collected from two hospitals in the north (Navrongo) and centre (Kumasi) of the country. In Nilo-Saharan speaking groups (purple), the Sudanese (1341CE: 1225–1660), Gumuz (1544CE: 1384–1718), Anuak (703: 427-1037CE), and Maasai (1646CE: 1584-1743CE), we infer greater proportions of West (blue) and East (orange) African Niger-Congo speaking surrogates in the major sources of admixture, indicating both that the Eurasian admixture occurred into groups with mixed Niger-Congo and Nilo-Saharan/Afroasiatic ancestry, and a clear recent link with Central and West African groups. Our findings suggest that a surprising consequence of antagonistic interactions between bacteria could be the promotion of adaptation via the action of directly mutagenic toxins. We provide supplementary analyses where this setting was over-ridden by allowing MALDER to start computing LD decay curves at short genetic distances (from 0.5cM), irrespective of any short-range correlations in LD between populations. (C) The third principle component (PC3, x-axis) represents geographical separation of Niger-Congo speakers, forming a cline from west to east Africans (D) results of the fineSTRUCTURE clustering analysis using copying vectors generated from chromosome painting; each row of the heatmap is a recipient copying vector showing the number of chunks shared between the recipient and every individual as a donor (columns);the tree clusters individuals with similar copying vectors together, such that block-like patterns are observed on the heat map; darker colours on the heatmap represent more haplotype sharing (see text for details); individual tips of the tree are coloured by country of origin, and the seven ancestry regions are identified and labelled to the left of the tree; labels in parentheses describe the major linguistic type of the ethnic groups within: AA = Afroasiatic, KS = Khoesan, NC = Niger-Congo, NS = Nilo-Saharan. Figure 3—figure supplement 1 shows comparative plots to those by Pickrell et al. We refer to the estimated coefficient for the lthpopulation as β^lk; to avoid over-fitting we exclude all populations for which β^lk< 0.001 and rescale so that ∑l≠kKβ^lk=1.0. Featured image contains simplified origin and data of samples studied, from the article. Our analysis provides an estimate of the timing of this expansion (Figure 5). The New Penguin History of the World, London, UK, Penguin Books. We admit that there are other areas of the continent where we do not have samples, and that this will have affected our interpretation of events. We use a genome-wide, haplotype-based, analysis to characterise the structure of genetic diversity and gene-flow in a collection of 48 sub-Saharan African groups. Global associations of national economic wealth are more robust with inflammatory bowel diseases than with obesity. We used MALDER (Pickrell et al., 2014), an implementation of ALDER designed to fit multiple exponentials to LD decay curves and therefore characterise multiple admixture events to allele frequency data. in two-population mode). Advertisement Specifically, we have (1) converted the date confidence intervals (CI) from +/- 1 standard error (SE) to +/- 1.96 SE to be more closely comparative to the 95% CIs generated by GLOBETROTTER, and (2) we have put dotted vertical lines at 1000 year intervals. Half (23) of the African groups represent subsets of samples collected from nine countries as part of the MalariaGEN consortium. 2014) and found to provide date estimates with tighter confidence intervals on simulated data than ROLLOF. Overall, approximately 80% of the AA genome is of West African ancestry and 20% of European Ancestry. Busby et al. We used the clustering algorithm implemented in fineSTRUCTURE (Lawson et al., 2012) to group individuals purely on the similarity of these copying vectors (Figure 1 and Figure 1—figure supplement 3). (2014), weighted LD curves can be used to identify the source of the gene-flow by comparing curves computed using different reference populations. For example, our analyses indicate that the Mossi share deep ancestry with Eurasian and Khoesan groups (Figure 3), but any description of the historical event leading to this observation is potentially biased by the discontinuity between extant populations and those present in Africa in the past. There are also several examples of humans adapting in response to infectious disease, for example at the LARGE gene in West Africans (Grossman et al., 2013), in response to pressure from Lassa fever, and at CR1 in response to malaria (Gurdasani et al., 2014). (2009), as implemented in the TREEMIX package (Pickrell and Pritchard, 2012). In a study based on glottochronology, Vansina (1995) suggests that the expansion started 5kya, whilst estimates based on linguistic diversity are slightly later, around 4kya (Blench, 2006). Analysis was by 2-sample T-test. Substituting these populations for their ancestry regions we get CK⁢h⁢o⁢e⁢s⁢a⁢n;E⁢u⁢r⁢a⁢s⁢i⁢am⁢a⁢x. Interpretation of such results is therefore challenging. Nevertheless, we explored whether our admixture approach could be used to gain insight into the Bantu expansion. Because of recombination, the identity of the closest relative will change depending on the admixture history between individual genomes. Nonetheless, the potential for genetic differences to underlie difference in disease should be guided by analyses of haplotype sharing between groups. Loh et al.
