2014) suggested differentiation between Khoe-San populations living north and south of the Kalahari Desert, an area that was dominated by lake Makgadikgadi during prehistoric times (i.e., > 10 kya) (Goudie 2003). Khoe-San collectively refers to Khoisan-speaking San huntergatherers and Khoekhoe herders, who historically inhabit arid regions in southern Africa. 2015). 2013; Choudhury et al. (2023) were common in their African data set (i.e., frequency >0.05) but rare outside of Africa (i.e., frequency <0.01). 2016). In contrast to the admixture in South Africa, seBSPs appeared to have replaced resident huntergatherer populations in Malawi and Mozambique with present-day individuals deriving 97% of their ancestry from the Bantu expansion (Skoglund et al. 3. The genetics of East African populations: a Nilo-Saharan 4.

A brief overview of the trans-atlantic slave trade, slave voyages: the Trans-Atlantic Slave Trade Database. What Race Has The Best Genetics In Bodybuilding History? (TOP 5 The exact admixture timings differ between populations (1.7 kya700 ya), with northern groups showing older dates than southern groups (Sengupta et al. Levantines and Arabians Have Different Origins, Middle East Genomic Study Finds The Arabians have deeper roots in Africa, while the Levantines roots lie in Europe and Anatolia in todays Turkey. 4A; Prendergast et al. However, many genes that are associated with immune response are highly pleiotropic, for example, major histocompatibility complex (MHC), human leukocyte antigen (HLA) genes, and apolipoprotein L1 (APOL1), complicating attempts to pin down the primary cause of recent adaptations. 2017). (2022) (see supplementary methods and table S1, Supplementary Material online). This signal of Neanderthal admixture observed in African genomes is most likely not the result of direct admixture but rather the result of admixture with back-migrating Europeans. 4B). Kulbila has the stats of a retro bodybuilder from the time of Frank Zane who was 59 and 185lbs in contest condition himself. 2022). Interestingly, the specific adaptive mutations seen in the Ethiopian Highlands differ from what has been observed in the Tibetan Plateau and the Andean Altiplano. This selection has largely occurred during the Holocene, making it a relatively recent phenomenon from an evolutionary perspective. However, the choice of reference populations for multiway admixed populations may be sensitive and critical in biomedical research (Chimusa et al. 2022). 2. 2014). In sub-Saharan Africa, strong selection for malaria resistance has contributed to the near fixation of the Duffy blood group, elevated rates of G6PD deficiency, and sickle cell disease (Kariuki and Williams 2020). For a more granular review of the demographic histories in light of the transatlantic slave trade of admixed population in the Americas, see Fortes-Lima and Verdu (2021). 2021; Gonzlez-Santos et al. 2020; Micheletti et al. The timing of selection for LP appears to differ in Africa as well: Strong selection for LP in Maasai herders appears to have occurred more recently than selection for LP in Europe (Schlebusch et al. 2010; Patterson et al. 2021). 2020a; Lipson et al. Diets vary across Africa, and these differences have provided ample opportunities for natural selection, be it via changes in metabolism, detoxifying harmful xenobiotics, or shifts in olfactory and taste perception. 2019). 2022). Serial founder effectThe successive loss of genetic variation when populations are sequentially founded by a small number of individuals. 2015; Mallick et al. The remaining ancestry can be predominantly assigned as European-like, with minor contributions from Native American groups in some populations (Micheletti et al. (2022) (see supplementary methods and table S1, Supplementary Material online). 2017; Fortes-Lima et al. 2015). 2020). The genetics of East African populations: a Nilo-Saharan 2011; Ranciaro et al. Thanks for every other informative website. 2017 and Lipson et al. They need to maintain their body temperature by keeping warm. 2015) and present-day Afro-Asiatic speakers (fig. 2012; Arauna et al. No amount of political correctness can obscure the reality that East Africans have a distinct, genetically-endowed body type and physiology. It has been hypothesized that the Arab expansion might also have introduced some sub-Saharanrelated ancestry through the slave trade (Newman 1995), which is supported by sub-Saharan ancestry in North African populations that could be traced to an admixture event 1.2 kya with a West African population (Henn et al. However, evidence supporting additional admixture events with unknown archaic homininsthe so-called archaic ghost populationswithin Africa is also mounting (Lorente-Galdos et al. WebThe Arab world has one of the highest rates of genetic disorders globally; some 906 pathologies are endemic to the Arab states, including thalassaemia, Tourette's syndrome, Wilson's disease, Charcot-Marie-Tooth disease, mitochondrial encephalomyopathies, and Niemann-Pick disease. Im a 100% East African Somali and wanted to know my genetic potential for bodybuilding. 2012; Hsieh, Woerner, et al. (2021). In the last decade, the importance of studying genetic variation in Africa has become more appreciated, and a heap of genetic studies of contemporary and ancient individuals has revealed complex population structure and history in Africa, complementing archeological and linguistic studies (e.g., Tishkoff et al. East African population has a very low food intake. 2012). 2. This understanding together with knowledge of its interactions with sociocultural factors that influence disease risk or treatment response can improve clinical care by improving the accuracy of genetic testing and/or assessment of therapeutic response (Hindorff et al. Cannot lose weight? Genetic influence on East African running success - ResearchGate They differ in their amount of Neanderthal DNA as well The peoples of the Middle East: 'Peace panel' from the Sumerian city of Ur. This gene flow from wBSPs into RHGs was inferred to have occurred 7 kya using models of site-frequency spectra (Hsieh, Veeramah, et al. However, Tallman et al. Subsequent studies of genome-wide data that included more Imazighen populations confirmed that most Arab and Imazighen populations are weakly genetically differentiated (Arauna et al. For a comprehensive review of the population history of Bantu speakers, see Schlebusch and Jakobsson (2018) as well as Choudhury et al. African-related ancestry is the highest in the British Caribbean (75%) and the United States (71%) and the lowest in South America (1112%) and Central America (8%, including Mexico) (Micheletti et al. 2012). 2020; Matjuda et al. 2012; Mallick et al. 1). Code used to generate this figure can be found at GitHub: https://github.com/LachanceLab/AfricanPopulationStructure. (2021) and Prendergast et al. Most contemporary African groups share some of their ancestries with groups from different geographic regions (fig. 2020a). 2022), it is imperative that ongoing efforts to sequence diverse populations on the African continent need to be expanded. For these reasons, studying more granular population structure in Africa, including potentially adapted genes, may increase our understanding of the genetics of complex traits (Chaichoompu et al. Third, we highlight how natural selection has shaped patterns of genetic variation across the continent, noting that gene flow provides a potent source of adaptive variation and that selective pressures vary across Africa. The Western Cape, at the southernmost part of South Africa, harbors one of the most diverse admixed populations, namely, the South African Coloured (SAC) population, which is the largest ethnic group in this region and has its origins slightly >350 ya (de Wit et al. Web1) Low Bench Press. Additional details about the deep population structure and the state of ancient DNA research in Africa can be found in reviews by Hollfelder et al. 4. Also will I make faster progress if i start hitting the gym consistently ? Through this admixture event, the Fulani likely received a European LP variant 13910*T (rs4988235) in the LCT gene region that was then positively selected, reaching frequencies between 18% and 60% in Fulani groups (Lokki et al. East African athletes have dominated these events since the 1960s, in both the male and female categories . A individual who possesses a enhanced genotype is well-suited to the sport of bodybuilding. Despite what is described here, we have only provided an overview of admixture events in the course of major migratory events, for example, the expansion of Bantu speakers. 2017; Skoglund et al. There Are Some Resones Of Why east african Have Good genetics For bodybuilding. 2017; Swart et al. Two admixture events involving a West African group and two different European groups dating to 1.8 kya and 300 years ago have been identified. However, the specific mutations conferring LP in Kenya (G-14010, rs145946881) and Sudan (G-13907, rs41525747) differ from LP mutations found in Northern Europe (T-13910, rs4988235) and the Middle East (G-13915, rs41380347) (Ranciaro et al. (2019), and Fortes-Lima et al. Aaron Pfennig, Lindsay N Petersen, Paidamoyo Kachambwa, Joseph Lachance, Evolutionary Genetics and Admixture in African Populations, Genome Biology and Evolution, Volume 15, Issue 4, April 2023, evad054, https://doi.org/10.1093/gbe/evad054. Most of our knowledge about African population history is derived from archeological and linguistic studies, as Africa has long been neglected in genetic studies (Popejoy and Fullerton 2016; Martin et al. We start by putting genetic variation in Africa into a global context and giving a brief overview of population structure in Africa inferred from ancient and extant genomes, focusing on huntergatherer groups and deep population structure in the continent. In South Africa, seBSPs received between 1.5% (e.g., the Tsonga) and 20% (e.g., the Tswana) gene flow from Khoe-San groups during independent admixture events (Sengupta et al. 2017; Lopez et al. 2021). 2012; Skoglund et al. african genetics bodybuilding Subsequently, the Mbuti (RHG) diverged 220 10 kya from all other human lineages, forming a second basal lineage (Schlebusch et al. 2017). Curious about your test results? The present meta-analysis included 100 populations from 36 Nevertheless, different genetic ancestries tend to cluster geographically (fig. 2009). or bad genetics for muscle growth This is of biomedical relevance (see below), and it also enables improved fine-mapping of causal variants in genome-wide association studies (GWAS) because casual variants are tagged by fewer other variants (Auton et al. 2019; Micheletti et al. then you got the germans and eastern europeans who also generally have very good genetics for muscle size. Petersen et al. (A) The stepwise spread of lactose persistence from northeastern Africa into eastern Africa and subsequently into southern Africa. Lastly, small amounts of admixture among Sahelian groups have been inferred from genome-wide markers (Fortes-Lima et al. Choudhury A, Sengupta D, Ramsay M, Schlebusch C. Coelho M, Sequeira F, Luiselli D, Beleza S, Rocha J. Hamid I, Korunes KL, Beleza S, Goldberg A. 2012; Lachance et al. 5. 2017; Vicente, Jakobsson, et al.

(2012) initially reported a clear genetic differentiation between Arabs and Imazighen. 2020) (fig. 2019; Durvasula and Sankararaman 2020; Schaefer et al. American and East Africans have the same height and weight but East Africans are the ones with much bigger muscles. Take care!! 2019). 2017). 2022). 2019; Scheinfeldt et al. Discover east african genetics bodybuilding 's popular Thus, there were ample opportunities for admixture between modern humans and archaic hominins. The early-split hypothesis suggests that BSPs split at an early stage north of the rainforest, with one group then moving directly South through the rainforest, whereas the other migrated East, north of the rainforest, toward the Great African Lakes. 2014; Macholdt et al. 2019; Wang et al. Similarly to phylolinguistics (e.g., Rexov et al. 2022). 2016). 2023), suggesting that the short stature of RHG evolved through positive selection on several loci. Nevertheless, African huntergatherers have the highest level of genetic diversity of extant populations and represent the most deeply branching human lineages even after accounting for recent admixture (Henn et al. 2018; Van De Loosdrecht et al. 3. 2019). Explore the latest Gene flowThe movement of individuals and their genetic material from one population to another population. The ability to break down starchy foods also appears to have been a target of selection. They also practice a lot of weight lifting. Bodybuilders work hard to perfect their six-pack abs and other muscles through intense training sessions, but many also have ripped bodies due to their genetics. 2021). 2014; Lipson et al. 2018). 2019). 2010; Montinaro and Capelli 2018). 2011, 2013; DAtanasio et al. Population structureSystematic differences in allele frequencies between subpopulations. 2014; Scheinfeldt et al. Additionally, multiple studies have also shown the significance of including ancestry to effectively direct the outcomes of treatment. Excellent site you have here.. Its difficult to find excellent writing like yours these days. 2016; Lopez et al. 2012; Breton et al. Here, we present an ancient human genome from Africa and use it to disentangle the effects of recent population movement into Africa. In contrast to the Fulani, Arab pastoralists have a higher mtDNA diversity, suggesting variable levels of female admixture into pastoral populations (kov et al. 2016; Vicente, Priehodov, et al. 2018). The genetic basis for elite running performance | British Journal of WebOutbound SDR. Genetic studies showed that the spread of Bantu languages, agricultural practices, and iron use 53 kya was accompanied by multiple migration waves of Bantu speakers from western Africa (i.e., current eastern Nigeria and western Cameroon) to other regions in sub-Saharan Africa (Tishkoff et al. Principal componentsA set of uncorrelated variables derived from the original data set through linear transformations, which maximize the variance between samples and reduce the dimensionality of the data while preserving the most important information. Discover eastafricanbody 's popular videos | TikTok 2017), although a recent study inferred a more ancient admixture date of 1.9 kya for Bantu speakers in Cabinda, Angola (Tallman et al. As expected, the Sahara, Red Sea, central African rainforest, and the Kalahari Desert act as ecological barriers. Genetic differentiation in East African ethnicities and its - PLOS This is due to the high percentage of fat in their muscles. (2022), respectively. Genetic ancestryThe genealogical paths through which an individual inherits DNA from specific ancestors in a reference population. For example, the Amahara people have adapted to low barometric pressure and hypoxia in the Ethiopian Highlands over the past 5,000 years. 2012). These are some genes I saw on here that carry an advantage Supplementary methods are available online at Genome Biology and Evolution online. 2014). 2020; Diallo et al. Another example of adaptation to extreme conditions are RHG groups, who evolved a short stature (mean adult height <160cm). For instance, two APOL1 haplotypes (G1 and G2) are protective against trypanosomiasis infection but are also associated with increased risk of kidney disease in African ancestry populations (Pereira et al. This requires meaningful engagement of community stakeholders on ethical, legal, and social issues as well as the communication of results, to guarantee that the benefits outweigh the risks (Lemke et al. 2020a). 2018), and African population history is of exceptional interest to human evolution. Individuals with shared genetic ancestry tend to be more genetically similar. Today, only a few traditional huntergatherer groups remain that live in small communities. 2012; Schlebusch et al. (2019) found additional evidence for gene flow from the Ju|Hoan (northern) into the Hoan (central), from the |Gui/Xade San (central) into the Naro (central), and from an undefined Khoe-San population into the Nama (southern). Watch popular content from the following creators: John O(@naijaboyjohn), 2018; Sirugo et al. (2017) concluded that a highly divergent haplotype of MUC7 introgressed into modern West Africans from an archaic lineage. 2020). (Epidermal Abundance) They have a thick outer layer of skin on their overall body. For instance, Ragsdale et al. Subsets of African genetic variation found outside of Africa also vary by region, indicating that multiple OOA migrations may have occurred (Rasmussen et al. Spatial visualizations of admixture and migration in Africa. 2014; Rees et al. In western Africa, wBSPs asymmetrically mixed with resident RHG groups, with RHG groups receiving higher amounts of gene flow from wBSPs (Jarvis et al. 2014; Gouveia et al. Im a 100% East African Somali and wanted to know my genetic potential for bodybuilding. We also see that East Africans have a lot of strong big people (muscle). (C) Extensive admixture between Sahelian populations with European groups in the West and Middle Eastern groups in the East, but only limited gene flow among Sahelian populations. 2017; Priehodov et al. 2010). Africa exhibits vast cultural and linguistic diversity, including a wide range of subsistence strategies and 2,000 spoken languages. As their genetic diversity is still significantly higher after accounting for recent admixture with nonKhoe-San groups, it reflects their historically larger Ne (Kim et al. Furthermore, Y chromosomal haplogroups are genetically more diverse in nomadic pastoralists groups, whereas mtDNA haplogroups are more diverse in sedentary farmers (kov et al. 2020). Paleolithic (Old Stone Age)The period of time in human evolution when people initially started using stone tools, extending from 3.3 million years ago (Mya) to 12 kya. This suggests that swBSPs took a different route directly south along the western coast and thus have different recent population histories than seBSPs (fig. 2019; Priehodov et al. The fact East African people have the highest intermuscular fat percentage among all. 4A). However, many more interesting admixture events are likely to have occurred along these migratory corridors. 2014). Possibly, Khoe-San were the only inhabitants of southern Africa for much of its prehistory (Schlebusch et al. How the climate affects the Africans body size. 2019; Wohlers et al. Khoe-San show the deepest split times, followed by RHG groups (e.g., Mbuti) and other extant populations. 2012; Hsieh, Veeramah, et al. Considered that low frequency is a feature used for determining pathogenicity, this suggests that current classifications of variant pathogenicity are confounded by a lack of diversity in study cohorts. Best Genetics by Country Ranked 2022. serious (Official Attempts to illuminate the deep population structure in Africa have been further aided by the emergence of ancient DNA from unadmixed huntergatherer individuals (e.g., Skoglund et al. 2019; Lucas-Snchez, Font-Porterias, et al. For these reasons, assuming regional population continuity, it has been argued for a southern African origin of modern humans (Henn et al. 2014; Macholdt et al. 2012; Hervella et al. 2014; Macholdt et al. Whereas sedentary farmers are stratified based on geography but not linguistics, the opposite is true for western Fulani pastoralists (Novkov et al. Sep 2018 - Feb 20201 year 6 months. 2022). For example, a recent study of 180 African huntergatherer genomes from 12 populations discovered 5.3 million novel genetic variants of which 78% are population-specific and of which many are predicted to be functionally relevant (Fan et al. How East Africans Have Good Genetics for Muscle Building This could either suggest deep population structure with EAHG and southern huntergatherer groups tracing some of their ancestries to a basal central African RHG lineage (Lipson et al. For instance, despite frequent droughts, the Khomani San have lived in the Kalahari Desert for thousands of years. FST (Fixation index)The extent of genetic differentiation of two populations. In contrast, there was a significant Eurasian paternal contribution (71.4%) defined by haplogroups R/I/G/N/O/J in the same group, and the Western European R1b haplogroup was prevalent at 44.4%. 2015; Vicente, Priehodov, et al. Mexican Genetics Study Reveals Huge Variation In line with archeological studies, genetic studies of Khoe-San confirmed that pastoralism spread from East Africa to southern Africa by demic diffusion (Breton et al. 2009; Auton et al. A subsequent study using samples from wider geographic and ethnolinguistic groups showed that eBSPs, seBSPs, and southwestern BSPs (swBSPs) are genetically closest to Bantu speakers from Zambia (Choudhury et al. 2020; Pereira et al. In light of this, we call for more (responsibly conducted) studies of genetic variation in Africa and research capacity building on the African continent. Although most of the genetic variation among Khoe-San populations is explained under an isolation-by-distance model (Montinaro et al. 2017). I also have the top 3 combat genes someone posted on here . Overall, this suggests multiple migration waves of Bantu speakers or that Khoe-San admixture did not occur immediately. Some of the strongest selection pressures on African populations involve pathogens and immune response, and few diseases have impacted human genomes as much as malaria. Lorente-Galdos et al. 6. The time to the most recent common ancestor (TMRCA) of such identified putatively introgressed haplotypes was found to be significantly older than the deepest split of all modern human lineages and similar to the TMRCA of introgressed Neanderthal haplotypes found in Eurasian populations (Hammer et al. WebDiscover short videos related to eastafricanbody on TikTok. In Africa, the Ethiopian Highlands are 1,500 meters above sea level, with summits as high as 4,550 meters above sea level. (2020). Many huntergatherer groups experienced declines in Ne during the Holocene and have small census population sizes today (Patin et al. Their complex origin of admixture is attributed to significant historical events that occurred within the last few millennia, starting 1.7 kya with the arrival of Bantu-speaking agro-pastoralists in South Africa (Sengupta et al.
