 Introduction. The Nubian expedition of the Lomonosov MSU carried out survey in the Onib Depression in December 2022. The survey revealed several surface scatters and two stone age sites Onib-1 and Onib-Outcrop.

Materials and methods. The materials for the article were artifacts (stone tools and debitage, fragments of ceramics) discovered at the surface scatters and sites as well as samples for OSL dating, loss-on-ignition and pollen analysis taken from sites. For comparison, we used stone tools discovered by the Nubian expedition of the USSR Academy of Sciences in 1961-1963. The artifacts found at the sites were documented (marked on a map, photographed and described). Several samples for OSL dating were taken at both sites. Sample preparation and gamma spectrometry, as well as OSL measurements, were conducted by standard methods. Analysis of the decoration of ceramic fragments found at the Onib-1 site was carried out. Also, based on the prepared thin sections, a technological and petroglyphic analyses of the obtained fragments were carried out. Samples were taken from different layers of the sites Onib-1 and Onib-Outcrop to determine the content of organic residues and spore-pollen analysis. Sample preparation and analysis were carried out following the standard procedures.

Results and Discussion. Analysis of the finds made at the sites indicates that the entire Wadi al-Allaqi region from the Red Sea Mountains to the Nile Valley was inhabited during the Neolithic period. OSL dating for Onib-1 and Onib-Outcrop sites indicates that the sedimentary deposits were formed during the Neolithic Subpluvial. These data are also confirmed by the results of ceramic analysis. The layers in which the ceramic fragments were found can be dated back to the 3^rd millennium BC. Petrographic analysis of thin sections of ceramics from Onib-1 site indicates the use of local material for the manufacturing of ceramics. The results of loss on ignition analysis did not reveal a sufficient content of organic residues for a comprehensive paleoecological study that overall indicates unfavorable conditions for the accumulation of organic matter in the studied deposits.

Conclusion. The results obtained indicate high prospects of continuing field research in the Onib Depression aimed at discovering and excavating Neolithic sites. © 2023. This work is licensed under a CC BY 4.0 license.

Introduction. Osteometric data of adult individuals of the anthropological series fr om the burial ground of the Golden Horde time "Natukhaevskoe 5" are presented for the first time in this work. Based on the standard measurements, patterns of the skeletal constitution of the buried are discussed. As part of this study, we tested the hypothesis about the difference in the morphological appearance of two samples, combined according to the type of funeral rite - stone boxes and burial grounds.

Materials and methods. The anthropological collection consists of the remains of 124 adult individuals, including 67 males and 57 females. Measurements of the postcranial skeleton were carried out according to the program of R. Martin (in version by V.P. Alekseev) according to 55 features. The degree of homogeneity of the male and female samples was determined using an intragroup analysis with the method of principal components for 10 features. The Mann-Whitney test was used to assess the statistical significance of differences.

Results. The male population was rather tall with a shortened robust humerus and an elongated forearm bones, the lower limbs were long and massive. Among the female group, there is also a tendency to lengthen the lower limbs, relative to the upper ones, mainly due to the lower leg. The conducted intragroup analysis did not reveal statistically significant differences between the two groups, united according to the type of funeral rite, neither among men nor among women. However, a large range of linear size variations was found among men buried in stone boxes. Compared to them, the sample from the ground pit is more homogeneous. A different picture is observed in the female sample, wh ere higher morphological diversity can be traced among those buried in the pits. © 2023. This work is licensed under a CC BY 4.0 license.

Introduction. This article is a publication of the first results of the work under the grant of the Russian Sciences Foundation "Scientific research of the Nubian Archaeological Expedition of the USSR Academy of Sciences 1961–1963…" related to the study of petroglyphs found during the work of the Nubian Expedition of the USSR Academy of Sciences, organized in 1961.

Materials and methods. After construction of the Aswan dam, the territories where the Soviet expedition worked as well as many other foreign scientific organizations, were flooded. Thus, the negatives of black-and-white photographs of petroglyphs preserved in the archives, along with some previously published data, are the only source of our information. Individual petroglyphs and groups of petroglyphs have never been outlined properly. This became our task at the first stage, when the drawings of individual signs were made in the Photoshop program (Adobe Photoshop CC version 10.1.2 ×64).

Results and discussion. In recent decades the study of petroglyphs of the Eastern and Nubian deserts has become one of the main areas of archaeologists’ work. It seems relevant to us to re-study the petroglyphs discovered by the Nubian Soviet expedition, analysis of some subjects and images, development of the main approaches to study.

The study of the approaches existing in the scientific literature to the dating and classification of petroglyphs of the Eastern and Nubian deserts gives an idea of the disputable nature of the most chronologies. The study of petroglyphs of Hukab-Karar is complicated by the limitations of the source – the quality of the photo does not always allow us to draw conclusions about the technique of execution of a particular sign. Nevertheless, a number of these petroglyphs can be dated by analogy with the petroglyphs from the well-known sites, as well as using published and handwritten descriptions of the participants of the Nubian expedition.

Conclusion. About 200 petroglyphs discovered by the Nubian Expedition of the USSR Academy of Sciences in a place called Umm-Aghaib (Huqab-Karar) have been published. Among them are numerous images of African fauna are presented. There are also images of hunting scenes, animals and birds, boats, tribal signs, anthropomorphic images dating to the widest historical period. © 2023.

Natural science museum collections are an important source of materials for scientific research. The Museum of Anthropology has a collection of casts from paleontological finds of primates. This catalog has never been published before. This work contains information about the composition and history of the formation of the collection.

Materials and methods. Documents from the Archive of the Museum of Anthropology of Moscow State University and articles in journals became the basis for writing this work. Analytical and chronological research methods were applied in the study.

Results and discussion. The section "Brief information on the history of the formation of the collection" contains information about the sources of replenishment of the paleoprimatological collection, the names of the scientists who transferred the items, the geography of receipts are given. The items were combined into collections on the grounds that they came from the same source at the same time.

The "Collection catalog" is represented by a table. The finds are divided by geological periods, listed in alphabetical order within the period.

Conclusion. A catalog of casts of finds of representatives of the order Primates (excluding the genus Homo) is presented in the article. In the course of working with the documents, we discovered that not all the accompanying papers were preserved. Work on reconstructing the history of the receipt of paleontological casts of primates will continue. © 2023. This work is licensed under a CC BY 4.0 license.

Introduction. In this paper, we compared patterns of longitudinal long bone growths of the Late Bronze Age population from Southern Urals, representing pastoral communities, predominantly cattle breeders, and the relatively synchronous agricultural population from Central Asia using standardized z-scores.

Materials and methods. The analyzed sample comes from two cemeteries of the Srubnaya culture in Pre-Urals (Karanayevsky and Chumarovo-1), and two cemeteries of the Srubnaya-Alakul cultural type in Trans-Urals (Nepluyevsky and Yulaly-8). The comparative sample represents data from Gonur Depe, a Bronze Age proto-urban center in Southeastern Turkmenistan. The sample sizes were 32 and 56 individuals respectively, aged between 2 and 12 years old. The measurements of all six long bones and updated reference Maresh standards (mid-20th century, USA) were used to calculate z-scores. The obtained z-scores were analyzed using both parametric methods and nonparametric statistics.

Results. Z-scores for the diaphyseal lengths differed significantly between the two analyzed samples. The distribution of z-scores for the Gonur Depe sample was more noticeably shifted towards lower values. In the Southern Ural sample, 6.7% of children had z-scores no lower than those in the reference group, while in the Gonur Depe sample this value constituted only 0.6%. Z-scores for the upper limb bones in both groups were significantly higher than those for the lower limb bones. In the Southern Ural sample, children under 6 years of age had significantly higher z-scores compared to 9–12-year old children. No such differences were found in the Gonur Depe sample.

Discussion. The pooled Bronze Age sample from Southern Urals showed overall less stunting from the reference group compared to the Gonur Depe sample. This is consistent with the hypothesis of a smaller long bone lengths and shorter stature in agricultural compared to pastoral populations. In both groups, the lower limb bones had lower z-scores compared to the upper limb bones, indicating that growth stunting relative to the reference values is more expressed for the lower limbs.© 2023.

Introduction. There are no fewer than two hundred algorithms for sex estimation based on cranial morphology, relying on statistical analysis of non-metric, linear, angular traits, and their combinations. Nevertheless, many physical anthropologists prefer to rely on visual observations. The objectives of this research encompass exploring potential reasons behind the preference for a visual approach and conducting an analysis of the comparative effectiveness of visual and statistical methods for sex estimation.

Materials and methods. The study is grounded in an analysis of publications related to methods of sex estimation based on cranial traits, spanning the past 70 years. Comparison of accuracy estimates was conducted using non-parametric tests, considering differences in statistical methods, validation approaches (no validation, cross-validation, independent test), and variable types (non-metric traits, craniometry, geometric morphometrics).

Results. General reasons for skepticism towards algorithms include unrealistic expectations regarding their capabilities, greater susceptibility to errors by models compared to humans, lack of control over classification. However, algorithms generally surpass experts in predicting the target variable. The average accuracy of visual sex estimations based on cranial traits is slightly lower than the estimates of statistical models and exhibits noticeable variability. The accuracy of estimations made by experienced anthropologists is comparable to the average performance of models. Nevertheless, the effectiveness of algorithms significantly diminishes when applied to datasets originating from sources other than the training set, particularly when dealing with craniometric traits. In a substantial portion of studies, the size of the training datasets is insufficient for a reliable assessment of model effectiveness, and the sex distribution is skewed towards male skulls, leading to some inflation of the accuracy of their estimates. Model effectiveness can also decline due to errors in the evaluation of non-metric traits, and the assessment of inter-researcher discrepancies does not allow for an evaluation of their impact on model accuracy.

Conclusion. Despite an extensive bibliography, there remains a lack of data on both the accuracy of the visual approach to sex estimation and the reliability of models with claimed high effectiveness. The adoption of flexible methodologies enabling researchers to independently control both variable selection and the composition of the training set will help overcome algorithm aversion and enhance the quality of estimates. © 2023.

Introduction. An assessment of the currently known data on intergroup variability of papillary patterns of fingers' middle phalanges suggests the possibility of using these characteristics to differentiate Eurasian populations.

Material and methods. The study conducted on the prints of fingers' middle phalanges of 1178 men from 12 ethno-territorial groups of Russia and Kyrgyzstan. These are mainly archival materials represented by impressions of the entire palmar surface of the hand. Therefore, we applied а classification that unites morphologically similar variants to eliminate possible errors in determining the types of skin patterns.

Results. Statistically significant differences revealed when comparing the proportions of dermatoglyphic features in Caucasian populations, on the one hand, and mixed Caucasian-Mongoloid or Mongoloid populations, on the other. The occurrence frequencies of straight and hook patterns increase, and the frequencies of distal arc and complex double patterns decrease in the presence of a Mongoloid (or Uralic) component.

The results of cluster analysis and multidimensional scaling confirmed the division of populations depending on the presence of a Mongoloid, including Ural, component in their racial composition. Within the main clusters, groups were differentiated according to anthropological similarity and territorial proximity.

The skin patterns’ complex of digital middle phalanges is very sensitive to the presence of a Mongoloid (or Uralic) component in Caucasian populations, as well as the main dermatoglyphic features of the hand. The differentiation of samples according to the patterns of the middle phalanges largely corresponds to the division based on classical racial and key dermatoglyphic characteristics. However, as a result of multidimensional scaling, the Volga-Kama populations were located further from the Caucasoid than both Mongoloid samples. Therefore, shares’ distribution of united dermatoglyphic signs in Mongoloid populations requires clarification using additional data.

Conclusion. The results of various statistical analyzes allow us to conclude that it is possible to use dermatoglyphic characteristics of digital middle phalanges to differentiate Caucasoid samples and groups with a Mongoloid (or Ural) component. The presence of the Mongoloid component in the groups is accompanied by a decrease in the complexity of the papillary patterns on the middle phalanges. © 2023.

Introduction. There are a number of genes, individual alleles of which or their combinations make the carrier susceptible to the disease. In the case of type 2 diabetes, obesity, and metabolic syndrome, the hypothesis of a “thrifty genotype” was put forward as a combination of gene alleles that provided their carriers with advantages in the prehistoric and historical past, but provoked morbidity now. Such a genotype should have previously been under the positive selection, whereas in the modern world it may play a negative role. It is also obvious that the expression of the thrifty genotype as well as the genes that form it and their alleles, should depend on anthropological and ecological conditions: the ecology of the region where the human population lives and their traditional subsistence and farming systems.

The aim of the proposed review is to systematize modern views on the problem of thrifty genotype with special attention to the evolutionary anthropological, and ecological aspects of the problem.

Materials and methods. Herein we represent a review of current data regarding the thrifty genotype hypothesis. The paper reviews the main theses of the hypothesis, its basis, and the arguments of supporters and critics. The evolutionary, anthropological, and ecological aspects of the thrifty genotype hypothesis are discussed.

Results. A significant number of experimental studies and reviews give an idea of the distribution of thrifty genotypes in populations of different origins and anthropological affiliations. However, the coverage of material and inclusion of population data in the analysis is uneven. The genetic geography of thrifty genotypes remains poor and, commonly, insufficiently studied. The most complete and methodologically correct systematization of primary materials on the prevalence of thrifty genotypes, their connection with the ecological conditions of the natural environment, and anthropogenic factors, including traditional subsistence and farming systems and the nature of nutrition, remains still relevant.

Conclusion. We consider the integrated ecological approach to be the most promising direction of theoretical research on the problem of “thrifty genotype”. The approach from the standpoint of the concept of “niche construction” removes the seeming contradictions between the main hypotheses considered in our review – the thrifty genotype, the drifty genotype and the thrifty phenotype. © 2023.

Introduction. The study of adiposity in children and adolescents is an important issue in the era of the global epidemic of obesity. Body mass index is the most common, but not the only body fat index. There are also indexes based on waist and hip circumferences. The purpose of this work is to analyze the age variability and correlation between various anthropometric indices and bioimpedance estimates of the percentage of body fat in children and adolescents.

Materials and methods. We analyzed the data of children and adolescents of both sexes 7-17 years old, 1885 boys and 1453 girls, collected in the course of cross-sectional anthropological surveys of schoolchildren in Moscow, Arkhangelsk and the Arkhangelsk region. Body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), hip-to-height ratio (HHtR) were calculated. The percentage of fat mass (% FM) was obtained by bioimpedance with the ABC-01 “Medas” device. Correlation analysis was used to assess the relationship between indices and %FM.

Results and discussion. The paper analyzes the age-related variability of height and weight, BMI, waist circumference, hip circumference, WHR, WHtR, HHtR and % FM in children and adolescents of both sexes. Age-related changes in % FM have clear sex differences. In girls, during puberty, there is an accumulation of fat mass, while in boys – its decrease. Body weight, BMI, waist circumference, hip circumference, HHtR increase in the process of growth, WHR and WHtR decrease. For all indicators, except for WHR, in boys and girls in younger age groups, correlations with % FM are high and decrease with age, reaching average values. While the correlations of WHR with %FM are weak in all studied age groups.

Conclusion. Based on the analysis performed, it is shown that body mass, waist circumference, hip circumference, BMI, WHtR, HHtR are good predictors of relative body fat mass, they significantly correlate with % FM, while WHR correlates very weakly. © 2023.

Introduction. A number of studies have shown that the Khalka rural pastoral population of Mongolia leading a traditional lifestyle is not characterized by acceleration of development and a secular trend in somatic characteristics of the body. The purpose is to study the morphological variability of head and face features in the adult rural Khalkha-Mongolian population against the background of variability of the same features in the Chuvash group and try to catch acceleration trends based on measuring head features.

Materials and methods. The data (370 men and 355 women aged 18-60) was obtained during anthropoecological expeditions in 1986-1990 in 4 Khalkha-Mongolian somons. As a comparative material, data on the Chuvash of Bashkiria were used. Regression analysis was applied. The age-related variability of normalized values of cephalometric traits was assessed using variance analysis. For the Mongolian and Chuvash populations, the coefficients of sexual dimorphism of individual features of the face and head (according to V. Deryabin`s formula), as well as the Mahalanobis distance between female and male samples were determined.

Results and discussion. For the studied characteristics (head length and breadth, the minimal forehead breadth and facial breadth, face height, facial and head indexes) in men, no reliable links were found between the variability of these traits and age. Variance analysis of normalized values of cephalometric signs revealed no differences in either the male or female Mongolian sample. The Mahalanobis distances calculated from the complex of head and face signs between the female and male Mongolian subsamples are noticeably smaller than the corresponding values obtained for the Chuvash group.

Conclusion. Comparative studies of the age dynamics of a number of measuring features of the head for about one and a half generations of the twentieth century in Khalkha-Mongols (adapted groups) and Chuvash (populations with impaired adaptation due to changes in socio-economic environmental factors) showed weakly pronounced morphological changes in the features on the head and face in the studied population groups. There were no significant age differences in the complex of features of the face and head in the Khalkhas populations. Data on sexual dimorphism of facial and head features in Mongols and Chuvash have been introduced into scholarly discourse, and in the Mongolian population the values of indicators of sexual dimorphism of cephalometric signs are less than in Chuvash sample. © 2023.

Introduction. The purpose of this work was to study the physical development of modern newborns in rural areas and analyze the influence on their basic anthropometric indicators of such biological factors as the serial number of pregnancy and childbirth, as well as the age of the parents at time of.

Materials and methods. Materials on rural children were collected in 2020–2022 in the Baranovichi district of the Brest region of the Republic of Belarus on the basis of the Children's City Clinic in the city of Baranovichi. The method of analyzing outpatient cards was used. A total of 231 newborn histories were studied (120 boys and 111 girls). The main anthropometric characteristics of children (body weight, body length, head circumference and chest circumference), as well as the age of the parents and the number of pregnancies and births in the mother were taken into account. The significance of differences was assessed based on Student's t-test. To conduct a comparative analysis of the dynamics over time of the physical development of newborns, materials from surveys of 1976–1978 were used.

Results. The bulk of modern births were women aged 25–34 years (66,6%). More than half of the newborns were born from repeated births – 79,2%. The average age of primiparous women was 25,2±0,7 years, multiparous women – 30,5±0,4. It was found that modern rural newborns had higher average indicators of physical development than newborns of 1976–1978, except for head circumference. Children from repeated births were larger in size, especially boys, in whom the difference reached a statistically significant level. Weak but significant positive correlations were noted between some indicators of the physical development of rural newborns with the age of the parents and the serial number of pregnancy and birth of the mother.

Conclusion. Analysis of changes in the main anthropometric indicators of physical development of rural newborns revealed an excess of the average parameters of body weight, body length (p<0,001) and chest circumference in children of both sexes, compared with infants of 1976–1978. Boys had higher basic anthropometric indicators than girls. © 2023. This work is licensed under a CC BY 4.0 license.
