Biocultural Emergence of the Amazigh (Berbers) in Africa
Biocultural Emergence of the Amazigh (Berbers) in Africa:Comment on Frigi et al. (2010) S. O. Y. Keita Keywords Berbers, Amazigh peoples, mtDNA lineages, gene flow, Maghreb, definition of "indigenous,", population history, language Frigi et al. [2010 (this issue)] present some new findings on a population of Amazigh—Berber speakers in Tunisia. Although their study is not exhaustive, they provide an outline of human population history in the Maghr…
Temporal Variation in Phenetic Affinity of Early Upper Egyptian Male Cranial Series
We carried out an exploratory historical biology study using temporally distinguished groups of predynastic-Early Dynastic male crania from the region of Upper Egypt. The objectives were, first, to determine the overall pattern of phenetic affinity between temporally sequential series and in relation to the earliest series and, second, to explore the possible meanings of the pattern of relationship to sociohistorical change. The cranial series we…

Variation in porotic hyperostosis in the Royal Cemetery complex at Abydos, Upper Egypt
Variation in the frequency and severity of porotic hyperostosis [porous defects], seen in the skulls of individuals buried at two First Dynasty cemeteries at Abydos, suggested differences in health and social conditions. Those buried near the kings had suffered from childhood deficiencies, while those associated with funerary enclosures in a second cemetery further to the north seemed to have benefited from occupational or social advantages. The …
Early Nile Valley Farmers From El-Badari
Male Badarian crania were analyzed using the generalized distance of Mahalanobis in a comparative analysis with other African and European series from the Howells’s database. The study was carried out to examine the affinities of the Badarians to evaluate, in preliminary fashion, a demic diffusion hypothesis that postulates that horticulture and the Afro-Asiatic language family were brought ultimately from southern Europe. (The assumption was mad…
History in the interpretation of the pattern of p49a,fTaqI RFLP Y-chromosome variation in Egypt
The possible factors involved in the generation of p49a,f TaqI Y-chromosome spatial diversity in Egypt were explored. The object was to consider explanations beyond those that emphasize gene flow mediated via military campaigns within the Nile corridor during the dynastic period. Current patterns of the most common variants (V, XI, and IV) have been suggested to be primarily related to Middle Kingdom and New Kingdom political actions in Nubia, in…
Genetics, Egypt, and History
Modern Egypt, the site of Africa's earliest state, lies near the crossroads of two other continents, and has had historic interactions with all its neighboring regions. This alone would make it an ideal place to study historical population biology. Egypt can also be conceptualized as a linear oasis in the eastern Sahara, one that traverses several regions of Africa. An oasis can be a way station or serve as a refugium, as well as be a place of se…
Explanation of the Pattern of P49a,f TaqI RFLP Y-Chromosome Variation in Egypt
Exploring northeast African metric craniofacial variation at the individual level
A principal components analysis was carried out on male crania from the northeast quadrant of Africa and selected European and other African series. Individuals, not predefined groups, were the units of study, while nevertheless keeping group membership in evidence. The first principal component seems to largely capture "size" variation in crania from all of the regions. The same general morphometric trends were found to exist within the African …
A study of vault porosities in early Upper Egypt from the Badarian through Dynasty I
Predynastic and Early Dynastic Upper Egyptian adult crania were assessed for porotic hyperostosis. This lesion (in adults) is believed most often to reflect iron deficiency anaemia that has occurred in childhood. The results indicate an increase in frequency from the Badarian to Naqada I with a subsequent decline to Dynasty I. This pattern is discussed in terms of subsistence change and its possible relationship to exposure to schistosomiasis, ho…

Diachronic patterns of dental hypoplasias and vault porosities during the predynastic in the Naqada region, Upper Egypt
The diachronic pattern of the frequencies of linear enamel hypoplasias and porotic hyperostosis was studied in temporally separated samples of adult predynastic Egyptian remains from the Naqada region, Upper Egypt. The samples covered a period of increasing population density and social complexity as well as decreasing Nile flooding in Egypt. First and second molars were evaluated for hypoplasias in material from the Naqada I, II, and III periods…
Interpreting African Genetic Diversity
The Persistence of Racial Thinking and the Myth of Racial Divergence
The concept and schema of race continue to exert a major influence on studies of human biology. The racial paradigm informs evolutionary studies in spite of evidence indicating that categories based on external phenotype are not valid. Racial thinking is especially prevalent in studies of Africa. It persists in defiance of genetic data that deconstruct such thinking, probably as a result of the sociocultural milieu, linger research traditions, an…
A brief review of studies and comments on ancient Egyptian biological relationships
A review of studies covering the biological relationship of the ancient Egyptians was undertaken. An overview of the data from the studies suggests that the major biological affinities of early southern Egyptians lay with tropical Africans. The range of indigenous tropical African phenotypes is great; and this range of variation must be considered in any discussion of the Nile Valley peoples. The early southern Egyptians belonged primarily to an …
Studies and Comments on Ancient Egyptian Biological Relationships
This discussion seeks to evaluate some of the previous writings on the biological origins of the northern Nile valley population or peoples, who came to be known as “ancient Egyptians.” The subject is of interest for three reasons. The first is that Egypt lies at a geographical crossroads and would have been subject to possible colonization or migration from all directions. The second is that Egypt is in Africa and there is no scientific reason t…
Further studies of crania from ancient Northern Africa
An analysis of First Dynasty crania from Abydos was undertaken using multiple discriminant functions. The results demonstrate greater affinity with Upper Nile Valley patterns, but also suggest change from earlier craniometric trends. Gene flow and movement of northern officials to the important southern city may explain the findings
Studies of ancient crania from northern Africa
Historical sources and archaeological data predict significant population variability in mid‐Holocene northern Africa. Multivariate analyses of crania demonstrate wide variation but also suggest an indigenous craniometric pattern common to both late dynastic northern Egypt and the coastal Maghreb region. Both tropical African and European metric phenotypes, as well intermediate patterns, are found in mid‐Holocene Maghreb sites. Early southern pre…
An analysis of crania from Tell‐Duweir using multiple discriminant functions
Historical and archaelogical evidence suggests that the Iron Age biblical city of Lachish had a multinational population of diverse geographical origins. A multivariate analysis of crania, using canonical discriminant functions and metric variables, tends to confirm this. The approach employed stresses that population discriminant analysis studies should be both biologically and statistically legitimate. An ecological interpretation of the data s…
