The Badarian culture provides the earliest direct evidence of agriculture in Upper Egypt during the Predynastic Era.Holmes, D., & Friedman, R. (1994). Survey and Test Excavations in the Badari Region, Egypt. Proceedings of the Prehistoric Society, 60(1), 105-142. doi:10.1017/S0079497X0000342X It flourished between 4400 and 4000 BC,
and might have already emerged by 5000 BC.
It was first excavated by Guy Brunton and Gertrude Caton-Thompson between 1922 and 1931.Brunton, Guy; Caton-Thompson, Gertrude (1928). The Badarian Civilisation and Predynastic Remains near Badari. British School of Archaeology in Egypt. ISBN 9780404166250. About forty settlements and six hundred graves have been located.
Little is known of their buildings, although remains of wooden stumps have been found at one site and may have been associated with a hut or shelter of unknown construction.
The deceased were wrapped in reed matting or animal skins and buried in pits with their heads usually laid to the south, looking west. This seems contiguous with the later dynastic traditions regarding the west as the land of the dead. They were sometimes accompanied by female mortuary figures carved from ivory, or with personal items such as shells, flint tools, amulets in the shape of animals like the antelope and hippopotamus, and jewelry made of ivory, quartz or copper. Green malachite ore has also been detected on stone palettes, perhaps for personal decoration. Tools included uniface, , bifacial and concave-base . Social stratification has been inferred from the burying of more prosperous members of the community in a different part of the cemetery. Black-topped pottery has been discovered in these cemeteries. These works with their distinctive rippled pattern are considered the most characteristic element of the Badarian culture.
Older and modern scholarship have characterised the Badarians as an indigenous, population that was rooted in a localised, context.
Egyptologist Frank Yurco considered the Badarians as exhibiting a "mix of and physical traits", and referenced older analysis of skeletal remains which "showed elements in the population of the earliest Badarian culture".
Recent archaeological evidence has suggested that the Tasian culture and Badarian Nile Valley sites were a peripheral network of earlier Northeast African cultures that featured the movement of Badarian, Saharan, and Nilotic populations.
A 1993 craniofacial study performed by the anthropologist C. Loring Brace reached the view that: "The Predynastic of Upper Egypt and the Late Dynastic of Lower Egypt are more closely related to each other than to any other population. As a whole, they show ties with the European Neolithic, North Africa, modern Europe, and, more remotely, India, but not at all with sub-Saharan Africa, eastern Asia, Oceania, or the New World."
However, various biological anthropological studies have demonstrated strong biological affinities between the Badarians and other Northeast African populations."When Mahalanobis D2 was used,the Naqadan and Badarian Predynastic samples exhibited more similarity to Nubian, Tigrean, and some more southern series than to some mid- to late Dynasticseries from northern Egypt (Mukherjee et al., 1955). The Badarian have been found to be very similar to a Kerma sample (Kushite Sudanese), using both the Penrose statistic (Nutter, 1958) and DFA of males alone (Keita,1990). Furthermore, Keita considered that Badarian males had a southern modal phenotype, and that together with a Naqada sample, they formed a southern Egyptian cluster as tropical variants together with a sample from Kerma". S.O.Y. Keita, a biological anthropologist, in 1990 conducted a craniometric analysis, which included early pre-dynastic Badarian and Naqada I skulls. Both series were found to "cluster with tropical Africans", and with the latter overlapping with Kerma kingdom.
In 2005, S.O.Y. Keita examined Badarian crania from predynastic upper Egypt in comparison to (Norway and Hungary) and various crania (Southern Africa, Mali and Kenya). He found that the predynastic Badarian series clustered much closer with the tropical African series. Although, no West Asian or other North African samples were included in the original study as the comparative series were selected based on "Brace et al.'s (1993) comments on the affinities of an upper Egyptian/Nubian epipalaeolithic series". Keita further noted that "additional analysis using material from Sudan, late dynastic northern Egypt (Gizeh), Somalia, Asia and the Pacific Islands show the Badarian series to be most similar to a series from the northeast quadrant of Africa and then to other Africans". Moreover, Keita criticised the methodology of the 1993 Brace study for excluding "the Maghreb, Sudan, and the Horn of Africa" from the designated Sub-Saharan group samples which he argued was nearly categorised and "(incorrectly)" as monolithic". Keita further commented on the findings of Boyce that whilst the "post-Badarian southern predynastic and a late dynastic northern series (called "E" or Gizeh) cluster together, and secondarily with Europeans", in the primary cluster with Egyptian groups there were also remains representing populations from ancient Sudan and recent Somalia.
In 2008, Keita found that the early predynastic groups in Southern Egypt which included Badarian skeletal samples, were similar to Nile-Valley material from areas to the south and north of Upper Egypt. Overall, based on the 9 variables, the dynastic Egyptians (includes both Upper and Lower Egyptians) showed much closer affinities with the included Northeast African populations than Europeans, who were more similar to the set of Late Dynastic Egyptians. In his comparison to the various Egyptian series, Greeks, Somali/Horn, and Italians were used. He also concluded that more material was needed to make a firm conclusion about the relationship between the early Holocene Nile valley populations and later ancient Egyptians.
Kanya Godde in a 2009 study evaluated population relationships by comparing cranial traits in twelve Nubian and Egyptian groups which included skeletal remains from the Badarian period. The results showed small biological distance between the groups, which indicate there may have been some sort of gene flow between these groups of Nubians and Egyptians or a common adaptation to similar environments. Godde further specified that the Badarians, Naqadans and Kerma Nubian samples clustered closely in spite of the timescale differences. She also cited previous anthropological studies and archaeological evidence which indicated close affinities between the Badarians and other southernly, African populations."On this basis, many have postulated that the Badarians are relatives to South African populations (Morant, 1935 G. Morant, A study of predynastic Egyptian skulls from Badari based on measurements taken by Miss BN Stoessiger and Professor DE Derry, Biometrika 27 (1935), pp. 293–309.Morant, 1935; Mukherjee et al., 1955; Irish and Konigsberg, 2007). The archaeological evidence points to this relationship as well. (Hassan, 1986) and (Hassan, 1988) noted similarities between Badarian pottery and the Neolithic Khartoum type, indicating an archaeological affinity among Badarians and Africans from more southern regions. Furthermore, like the Badarians, Naqada has also been classified with other African groups, namely the Teita (Crichton, 1996; Keita, 1990), while the Gizeh sample clustered with the Maghreb and Sedment (Dynasty IX Egyptians) (Keita, 1990). Nutter (1958) noted affinities between the Badarian and Naqada samples, a feature that Strouhal (1971) attributed to their skulls possessing "Negroid" traits. Keita (1992), using craniometrics, discovered that the Badarian series is distinctly different from the later Egyptian series, a conclusion that is mostly confirmed here. In the current analysis, the Badari sample more closely clusters with the Naqada sample and the Kerma sample". In 2020, Godde analysed a series of crania which included two Egyptian (predynastic Badarian and Naqada series), a series of A-Group Nubians, and a Bronze Age series from Lachish, Palestine. The two pre-dynastic series had strongest affinities, followed by closeness between the Naqada and the Nubian series. Further, the Nubian A-Group plotted nearer to the Egyptians and the Lachish sample placed more closely to Naqada than Badari. According to Godde the spatial-temporal model applied to the pattern of biological distances explains the more distant relationship of Badari to Lachish than Naqada to Lachish as gene flow will cause populations to become more similar over time. Overall, both Egyptian samples were more similar to the Nubian series than to the Lachish series.
In 2023, Christopher Ehret wrote that the physical anthropological findings from the "major burial sites of those founding locales of ancient Egypt in the fourth millennium BCE, notably El-Badari as well as Naqada, show no demographic indebtedness to the Levant". Ehret specified that these studies revealed cranial and dental affinities with "closest parallels" to other longtime populations in the surrounding areas of Northeast Africa "such as Nubia and the northern Horn of Africa". He further commented that "members of this population did not come from somewhere else but were descendants of the long-term inhabitants of these portions of Africa going back many millennia”. Ehret also cited existing, archaeological, linguistic and Genetics data which he argued supported the demographic history.
Some researchers have critiqued the reliability of craniology—the study of skull shapes and sizes—in drawing definitive conclusions about the biological relationships and identities of ancient populations. Critics argue that cranial morphology can be influenced by various factors which may not accurately reflect genetic ancestry or population dynamics. According to S.O.Y. Keita, relying solely on cranial measurements without considering broader archaeological and environmental contexts can lead to oversimplified or misleading interpretations. Keita emphasizes that "cranial metrics alone are insufficient for determining discrete biological populations, especially in regions with significant genetic diversity and historical population movements".
Furthermore, advancements in genetic and genomic studies have provided more robust tools for investigating ancient human populations. Researchers such as Ron Pinhasi and Jay T. Stock strongly advocate for integrating craniometric data with genetic, archaeological, and environmental evidences to offer a more comprehensive understanding of population history and biological relationships.
They argue that conclusions drawn strictly from craniological or other morphological analyses about cultural or ancestral relationships should be approached with caution and supported by multiple lines of evidence. Genetic studies can reveal ancestry and migration patterns that are not discernible through morphology alone. Advancements in ancient DNA analysis and other bioarchaeological methodologies have provided more precise tools for investigating genetic relationships and migration patterns.
Dental trait analysis of Badarian fossils conducted in a thesis study found that they were closely related to other Afroasiatic-speaking populations inhabiting Northeast Africa and the Maghreb. Among the ancient populations, the Badarians were nearest to other (Naqada culture, Hierakonpolis, Abydos and Kharga Oasis in Upper Egypt; Hawara in Lower Egypt), and C-Group culture and Pharaonic era skeletons excavated in Lower Nubia, followed by the A-Group culture bearers of Lower Nubia, the Kerma Culture and Kush populations in Upper Nubia, the Meroe, X-Group and Christian era period inhabitants of Lower Nubia, and the Kellis population in the Dakhla Oasis. Among the recent groups, the Badari markers were morphologically closest to the Chaoui people and Kabyle people Berbers populations of Algeria as well as Bedouin groups in Morocco, Libya and Tunisia, followed by other Afroasiatic-speaking populations in the Horn of Africa. The Late Roman era Badarian skeletons from Kellis were also phenotypically distinct from those belonging to other populations in Sub-Saharan Africa.
While dental trait analysis has been a useful tool in bioarchaeology for assessing biological relationships among ancient populations, recent scholarship highlights its limitations. Researchers caution that relying exclusively on dental morphology can be problematic due to factors such as environmental influences, dietary practices, and genetic drift, which can affect dental characteristics independently of genetic ancestry. Dental traits may exhibit convergent evolution, where similar dental features develop in unrelated populations due to similar selective pressures, potentially leading to misinterpretations of population affinities.
Bioanthropologist Christy G. Turner II and colleagues have emphasized that "dental morphology alone may not provide a complete picture of population relationships and must be integrated with other lines of evidence." They advocate for a multidisciplinary approach to achieve a more comprehensive understanding of an ancient population.
In 2011, Michelle Raxter examined the changes in limb proportions and body sizes in ancient Egyptians in a worldwide and regional comparative thesis study. The study featured 92 males and 528 female samples which included skeletal remains from the Badarian period. The Egyptian body sizes were compared with Nubian samples, as well as to modern Egyptian samples and other higher and lower latitude populations. Overall, the study found that "Ancient Egyptians have more tropically adapted limbs in comparison to body breadths, which tend to be intermediate when plotted against higher and lower latitude populations. These results may reflect the greater plasticity of limb lengths compared to body breadth. The results might also suggest early Mediterranean and/or Near Eastern influence in Northeast Africa". Raxter also acknowledged that a larger sample collection from the early and late predynastic groups would have enabled "closer examination of biological changes in the transition to agriculture".
Limb proportion analysis has been utilized in physical anthropology to study climatic adaptations and infer aspects of population history among ancient groups. Measurements such as the brachial index (upper arm to forearm ratio) and crural index (thigh to lower leg ratio) have been used to assess thermoregulatory adaptations according to Allen's rule, which posits that populations in warmer climates tend to have longer limbs to dissipate heat, while those in colder climates have shorter limbs to conserve heat.
Scholarship has also highlighted the limitations of drawing definitive conclusions about cultural identity or ancestry based solely on limb proportions. Factors such as environmental influences during growth, nutritional status, and genetic admixture can affect limb development independently of genetic heritage or cultural practices. Additionally, plasticity in human growth can result in limb proportion variations within a population over relatively short time spans, potentially leading to misinterpretations when inferring long-term population histories. Anthropologist Tenton W. Holliday further cautions that "while limb proportions can provide insights into broad patterns of climatic adaptation, they are not definitive indicators of genetic relationships or cultural affiliations among ancient populations." Holliday emphasizes the importance of integrating multiple lines of data for a more accurate biological history.
Although no remains of pre-dynastic material has been sequenced, various DNA studies have found Christian-era and modern Nubians, along with modern Afro-Asiatic speaking populations in the Horn of Africa to be descended from a mix of West Eurasian and African populations.
