Genetics A Y-chromosome study by Wood et al. (2005) tested various populations in Africa for paternal lineages, including 26 Maasai and 9 Luo from Kenya and 9 Alur from the Democratic Republic of Congo. The signature Nilotic paternal marker Haplogroup A3b2 was observed in 27% of the Maasai, 22% of the Alur, and 11% of the Luo. Haplogroup B, another characteristically Nilotic paternal marker according to Gomes et al. (2010), was found in 22% of Wood et al.'s Luo samples and 8% of the studied Maasai. The E1b1b haplogroup was also observed in 50% of the Maasai, which is indicative of substantial gene flow into this population from Cushitic males. In addition, 67% of the Alur samples possessed the Sub-Saharan E2 haplogroup. Another study by Hassan et al. (2008) analysed the Y-DNA of populations in the Sudan region, with various local Nilotic groups included for comparison. The researchers found the signature Nilotic A and B clades to be the most common paternal lineages amongst the Nilo-Saharan speakers, except those inhabiting western Sudan, where an appreciable North African influence was noted. Haplogroup A was observed amongst 62% of Dinka, 53.3% of Shilluk, 46.4% of Nuba, 33.3% of Nuer, 31.3% of Fur and 18.8% of Masalit. Haplogroup B was found in 50% of Nuer, 26.7% of Shilluk, 23% of Dinka, 14.3% of Nuba, 3.1% of Fur and 3.1% of Masalit. The E1b1b clade was also observed in 71.9% of the Masalit, 59.4% of the Fur, 39.3% of the Nuba, 20% of the Shilluk, 16.7% of the Nuer, and 15% of the Dinka. Hassan et al. attributed the atypically high frequencies of the haplogroup in the Masalit to either a recent population bottleneck that likely altered the community's original haplogroup diversity or to geographical proximity to E1b1b's place of origin in North Africa, where the researchers suggest that the clade "might have been brought to Sudan from[...] after the progressive desertification of the Sahara around 6,000–8,000 years ago". Henn et al. (2008) similarly observed Afro-Asiatic influence in the Nilotic Datog of northern Tanzania, 43% of whom carried the M293 sub-clade of E1b1b. mtDNA Unlike their paternal DNA 543, the maternal lineages of Nilotes in general show low-to-negligible amounts of Afro-Asiatic and other extraneous influences. An mtDNA study by Castri et al. (2008) examined the maternal ancestry of various Nilotic populations in Kenya, with Turkana, Samburu, Maasai and Luo individuals sampled. Almost all of the tested Nilotes belonged to various Sub-Saharan macro-haplogroup L sub-clades, including L0, L2, L3, L4 and L5. Low levels of maternal gene flow from North Africa and the Horn of Africa were also observed in a few groups, mainly via the presence of mtDNA haplogroup M and haplogroup I lineages in about 12.5% of the Maasai and 7% of the Samburu samples, respectively. Autosomal DNA The autosomal DNA of Nilotic peoples has been examined in a comprehensive study by Tishkoff et al. (2009) on the genetic affiliations of various populations in Africa. According to the researchers, Nilotes generally form their own Sub-Saharan genetic cluster. The authors also found that certain Nilotic populations in the eastern Great Lakes region, such as the Maasai, showed some additional Afro-Asiatic affinities due to repeated assimilation of Cushitic-speaking peoples over the past 5000 or so years. Anthropology Physically, Nilotes are noted for their typically very dark skin color and slender, tall bodies. They often possess exceptionally long limbs, particularly vis-a-vis the distal segments (forearms, calves). This characteristic is thought to be a climatic adaptation to allow their bodies to shed heat more efficiently. Sudanese Nilotes are regarded as one of the tallest people in the world. Roberts and Bainbridge (1963) reported average values of 182.6 cm (71.9") for height and 58.8 kg (129.6 lbs) for weight in a sample of Sudanese Shilluk. Another sample of Sudanese Dinka had a stature/weight ratio of 181.9 cm/58.0 kg (71.6"/127.9 lbs), with an extremely ectomorphic somatotype of 1.6-3.5-6.2. In terms of facial features, Hiernaux (1975) observed that the nasal profile most common amongst Nilotic populations is broad, with characteristically high index values ranging from 86.9 to 92.0. He also reported that lower nasal indices are often found amongst Nilotes who inhabit the more southerly Great Lakes region, such as the Maasai, a fact which he attributed to genetic differences. Additionally, it has been remarked that the Nilotic groups presently inhabiting East Africa are sometimes also smaller in stature than those residing in the Sudan region. Campbell et al. (2006) recorded measurements of 172.0 cm/53.6 kg (67.7"/118.2 lbs) in a sample of agricultural Turkana in northern Kenya, and of 174.9 cm/53.0 kg (68.8"/116.8 lbs) in pastoral Turkana. Hiernaux similarly listed a height of 172.7 cm (68") for Maasai in southern Kenya, with an extreme trunk/leg length ratio of 47.7. Many Nilotic groups also excel in long and middle distance running. It has been argued that this sporting prowess stems from their exceptional running economy, which in turn is a function of slim body morphology and slender legs, as well as a culture of running to school from a young age. A study by Pitsiladis et al. (2006) questioning 404 elite Kenyan distance runners found that 76% of the international-class respondents hailed from the Kalenjin ethnic group and that 79% spoke a Nilotic language.
