Geography is a well-known factor shaping genetic variation in human populations. However, the potential role played by cultural variables remains much understudied. This study investigates the impact of socio-cultural variables on genomic similarity and the saliva microbiome, using data from populations in Lesotho and Namibia. Geographic distance within Lesotho increases genetic differentiation, while

Genetic variability of Roma population was shaped by the strong influence of genetic drift and gene flow during the migrations from their ancestral homeland in Indian subcontinent towards Europe. In addition, social stigmatization in many European countries, as a consequence of different cultural heritage and social practices, induced further genetic differentiation and sub structuring within the population

Bone histomorphometry refers to the study of the structure and microscopic features of bone tissue. It involves the measurement and assessment of bone microanatomy, and it provides valuable information on bone properties. Through the application of histomorphometry, researchers can acquire information on bone metabolism and on remodeling dynamics, which is useful to the study of bone health. During

The questions -When did humans arrive in the Americas? Who were they, or from where did they come from? -are enduring and fascinating inquiries that have been approached from different perspectives, thanks to the contributions of archaeology, biological anthropology, and linguistics, among other disciplines. As a result, and after several centuries of studies, this body of research inspired several

El Castillo cave is a well-known site because of its Paleolithic archaeology and parietal rock art. This paper is focused on the human remains found by V. Cabrera in the Mousterian Unit XX assigned to MIS 4 and early MIS 3. The fossils consist of one upper left second premolar (ULP4), one incomplete proximal hand phalanx, and one partial femoral head. The tooth and the phalanx were assigned to adults

Cortical bone and dentine share similarities in their embryological origin, development, and genetic background. Few analyses have combined the study of cortical bone and dentine to quantify their covariation relative to endogenous and exogenous factors. However, knowing how these tissues relate in individuals is of great importance to decipher the factors acting on their evolution, and ultimately

Many people and organizations misunderstand the concept behind the name Pygmy. This misunderstanding leads them to misinterpretations and erroneous judgements about its use. This article goes back to the origin of the name in order to clarify the meaning that it has today, especially for the Pygmies themselves. The term 'pygmy' originated in ancient Greece where it was employed for a legendary people

North Africa is a key area for understanding cultural processes that led to the Acheulean pan - African emergence and expressions and the related hominin population dynamics. Unfortunately, little is known about the early Acheulean in this vast area of the African continent due to the scarceness of archaeological sites in stratigraphic context with reliable chronometric data, human remains, and technological

Of the many critical phases of human evolution, one of the most investigated is the transition from the Middle to the Upper Palaeolithic with the pivotal bio-cultural substitution of Neanderthals by Homo sapiens in Western Eurasia. The complexity of this over ten thousands years phase raises from the ensemble of evidence ascribed to the diverse adaptations expressed by Neanderthals and the first representatives

Ancient DNA (aDNA) studies have deployed genetic material from archaeological contexts to investigate human dispersals and interactions, corroborating some longstanding hypotheses and revealing new aspects of human history. After drawing the broad genomic strokes of human history, geneticists have discovered the exciting possibilities of applying this method to answer questions on a smaller scale.

The major genetic divergences among non-Africans took place within a relatively short period of time, between 50 and 40 thousand years ago. These events shaped human diversity worldwide and set the basis for our current understanding of demographic history, patterns of adaptation and genetic burden across human populations. While the global picture appears already set, with the main human expansion

This paper presents an updated view on the morphological and functional significance of the human respiratory system in the context of human evolutionary anatomy. While usually the respiratory system is treated either from a craniofacial perspective, mostly in the context of nasal evolution and air-conditioning, or from a postcranial perspective featuring on overall thoracic shape changes, here we

The question of how complex morphologies evolve, given constraints imposed by genetic, developmental and functional factors, has been a topic of inquiry for many decades. In the mid-twentieth century the study of morphological trait covariation, and the implications of this for evolutionary diversification, was developed under the general concept of "morphological integration". Given the polygenic

The relationship between anthropology and neuroscience has always been friendly but controversial, because they embrace inclusive common topics (human beings and their brains) although following distinct approaches, often more holistic and speculative in the former field, more reductionist and quantitative in the latter. In recent decades, novel disciplines have been proposed to bridge the gap between

Since prehistoric times, Italy has represented a bridge between peoples, genes and cultures. Its peculiar geographical position explains why: it is located in the center of the Mediterranean Sea, flanked by the Balkans and the Hellenic Peninsula to the east, Iberia to the west and surrounded by North Africa to the south and central Europe to the north. This makes Italy of extraordinary interest for

In this contribution I will review the development of ideas about a recent African origin for our species over the last 50 years, starting from the time of my PhD in the early 1970s. I will examine the instructive and quite different interpretations placed on the 1979 discovery of a partial Neanderthal skeleton associated with a Châtelperronian industry at the rock shelter of St-Césaire in France,

The present-day diversity of southern African populations was shaped by the confluence of three major pre-historic settlement layers associated with distinct linguistic strata: i) an early occupation by foragers speaking languages of the Kx'a and Tuu families; ii) a Late Stone Age migration of pre-Bantu pastoralists from eastern Africa associated with Khoe-Kwadi languages; iii) the Iron Age expansion

Paleoanthropology's relationship with evolutionary theory has not been entirely happy. The anatomists who dominated paleoanthropology for its first century had little interest in biological diversity and its causes, or in hominins' place in that diversity, or in the rules and principles of zoological nomenclature - which they basically ignored entirely. When, as the twentieth century passed its midpoint

Seasonality plays a critical role in determining the yearly dietary variability of many nonhuman primates living in tropical and subtropical environments. Much previous research has emphasised the seasonal importance of both preferred resources-eaten whenever available-and fallback foods-eaten during periods of scarcity to compensate for an insufficient availability of preferred resources. However

Colour strongly shapes our perception of the world and plays a main role in the emergence of language and in the transmission of information. It has been shown that systematic use of ochre, along with other cultural traits that reflect cognitive complexity, disappear and reappear from the archaeological record, suggesting that cultural transmission follows discontinuous trajectories that to this day

Here we present the results of a microcontextual analysis of purported combustion features recovered from Middle and Upper Paleolithic occupations at the cave site of Fumane, Italy. Our analyses, which integrate micromorphology with organic petrology, show that only a few of the features represent primary, intact hearths; some of them show evidence for various phases of anthropogenic reworking, either

Scientific studies on the genetic proximity of Jews undertake to shed light on "who or what Jews really are". However, various scientists and scholars have warned that such studies reify racial thinking. This essay delineates and contextualizes the debate held between various geneticists and social scientists on the danger of reification within the Jewish context. This is mainly a debate about the

Morphological variation of the human pelvis, and particularly the hip bone, mainly results from both female-specific selective pressure related to the give birth of large-headed newborns, and constraints in both sexes for efficient bipedal locomotion, abdominal stability, and adaptation to climate. Hip bone morphology has thus been extensively investigated using several approaches, although the nuances

In recent decades, the scientific community has become aware of the importance of science being effectively open in order to speed up scientific and technological progress. In this context, the achievement of a robust, effective and responsible form of data sharing is now widely acknowledged as a fundamental part of the research process. The production and resolution of human genomic data has steadily

This study aims to carry out the first geometric morphometric analysis of the 3D size and shape of the full series of cervical vertebrae delving into variability related to sex and population background. For this reason, we analyzed the cervical vertebrae of both males and females belonging to Europeans, Africans, and Greenland Inuit. We 3D-scanned a total of 219 cervical vertebrae of males and females

In two publications from 1967 and 1971, M. Masali described human skeletal remains presumed to have been found in the Balzi Rossi caves (Ventimiglia, Italy), based on a signed note dated to 1908. Since then, the remains - dubbed "Conio's Finds" and preserved at the University of Torino - had not been further studied. We performed a multidisciplinary investigation aimed at clarifying the geographical

This study argues that the equipment of the Tyrolean Iceman offers a unique perspective for understanding the macroevolutionary-scale functional continuity between later Pleistocene and Holocene human technologies. The Iceman was discovered in 1991 in the Ötztal Alps and can be dated to around 3300 BC, corresponding to the North Italian early Copper Age. In his gear there are several technologies which

The bony symphyseal surface is an important trait for age-at-death estimation from human skeletal remains. In this paper, we demonstrate for the first time that the outline of the human symphyseal surface is sexually dimorphic and that it changes with age. We present a geometric morphometric analysis based on a sample of 323 symphyseal pubic bones from males and females in the age range of 14 to 82

One of the main concerns of paleoanthropologists is to make a correct interpretation of the variability observed in the fossil record. However, the current knowledge about sexual dimorphism in the human lineage comes mainly from the study of modern human, Neanderthal and pre-Neanderthal populations, whereas information available about the intrapopulation variability of the groups that preceded these

KNM-OG 45500 is a hominin fossil composed of parts of a frontal bone, left temporal bone, and cranial vault pieces. Since its discovery along the Olorgesailie Formation (Kenya) in 2003, it has been associated with the Homo erectus hypodigm. The specimen, derived from a geological context dated to ca. 900 Ka BP, has been described as a very small individual of probable female sex. However, despite its

The cultural dynamics that led to the appearance of the Aurignacian have intrigued archaeologists since the start of Paleolithic research. However, cultural reconstructions have often focused on a restricted region of Europe, namely the northern Aquitaine Basin. The Mediterranean Basin, though, is also a region worthy of consideration when testing if the Protoaurignacian was followed by the Early Aurignacian

The discovery of the nearly complete Plio-Pleistocene skeleton StW 573 Australopithecus prometheus from Sterkfontein Member 2, South Africa, has intensified debates as to whether Sterkfontein Member 4 contains a hominin species other than Australopithecus africanus. For example, it has recently been suggested that the partial skeleton StW 431 should be removed from the A. africanus hypodigm and be

Recent finds in hominin fossil environments place the transition to terrestriality in a wooded or forested habitat. Therefore, forest-dwelling apes can aid in understanding this important evolutionary transition. Sex differences in ape locomotion have been previously attributed to sexual dimorphism or ecological niche differences between males and females. This study examined the hypothesis that differential

Numerous factors, including family planning and modern contraception, disturb the potential associations between the number of children born and genetic factors in modern Western societies. The current progress of medicine and a relatively high level of well-being make it hard to test the association between children's survival rates and genetic factors in Western societies either. The goal of the

Ambiguities within species description and identification may compromise research validity. Species identification has typically been based upon morphological characteristics, yet recent technological advances have led to identifications achieved via DNA approaches, including DNA barcoding. DNA barcoding studies typically use cytochrome c oxidase subunit I (COI) as the proposed universal molecular

The Florisbad fossil cranium was found in South Africa in 1932. Different authors proposed a taxonomic affinity with early Homo sapiens, Neandertals or late Homo heidelbergensis. Here, we review its neurocranial morphology, to supply an updated perspective on its paleoneurological features. The curvature of the frontal squama is definitely within modern human variation, although the anterior cranial

This report aims to give notice of and provide a more detailed dataset and detailed remarks on what can be considered a one-of-a-kind hominin fossil walking pattern: Trackway B of the Foresta ichnological site (Tora e Piccilli, Caserta, Central Italy). Although the site is known since 2003, only recently has the study been performed by means of the newest photogrammetric and experimental techniques

Scenarios for the dispersal of Homo sapiens in Southern Europe and in the Mediterranean basin have been uncertain, given the scarceness of osteological samples and the simplicity of the proposed archaeologically-based settlement hypotheses. According to available data, the first anatomically modern humans entered Sicily during the Late Pleistocene, coming from the Italian peninsula. A presumably small

The scientific study of the victims of the 79 AD Vesuvius eruption began with the first discovery in the 1980s of hundreds of skeletons of people who had taken refuge in the suburban area of Herculaneum. Hundreds of human victims were found crowding the beach and a series of waterfront chambers, fixated into a final posture by the first of the deadly incoming pyroclastic currents. The towns of Herculaneum

Human populations living at high altitude evolved a number of biological adjustments to cope with a challenging environment characterised especially by reduced oxygen availability and limited nutritional resources. This condition may also affect their gut microbiota composition. Here, we explored the impact of exposure to such selective pressures on human gut microbiota by considering different ethnic

Against the background of the results of surveys carried out previously on American, Polish, and European academics, we present new data on the perception of races among non-biological anthropologists. In five case studies, we surveyed 585 respondents belonging to the academic community (of biologists and cultural anthropologists) and ordinary people from three European countries: Poland, Czech Republic

A Neanderthal endocast, naturally formed by travertine within the crater of a thermal spring, was found at Gánovce, near Poprad (Slovakia), in 1926, and dated to 105 ka. The endocast is partially covered by fragments of the braincase. The volume of the endocast was estimated to be 1320 cc. The endocast was first studied by the Czech paleoanthropologist Emanuel Vlček, who performed metric and morphological

The aim of this paper is to give a practical overview, showing how recent available digital technology can be combined to build a laboratory capable to produce 3D (and reproduce in 3D) anatomical models for research, teaching and museum exhibitions on topics related to anatomy, morphology in natural sciences, biology and medicine. We present workflows in our Virtual Morphology Lab that can be used

North Africa features some of the earliest manifestations of the Middle Stone Age (MSA) and fossils of our species, Homo sapiens, as well as early examples of complex culture and the long distance transfer of exotic raw materials. As they are elsewhere, lithics (i.e., stone tools) present by far the most abundant source of information on this cultural period. Given the importance of North Africa in

In paleoanthropological literature, the use of the term "mosaic" (mosaic evolution, mosaic trait, mosaic species, and so on) is becoming more and more frequent. In order to promote a clarification of the use of the concept in literature, we propose here a classification in three different meanings of the notion of mosaic in human evolution: 1) morphological (inter-specific and intra-specific) instability
