Divergent Macroscopic and Microscopic Patterns in Bony‐Fibrous Entheses Revealed by a Multidisciplinary Approach
The first human fossil from the Ruidera site (Castilla-La Mancha, Spain): A partial parietal and its implications for Middle Pleistocene hominin variability in Southern Europe
We report a new Middle Pleistocene paleoanthropological locality located in southern Iberian Peninsula, Ruidera, and describe a newly discovered partial parietal bone (RVH-1). The fossil was chronologically constrained through a combination of uranium-series and optically stimulated luminescence dating methods. In particular, the human fossil-bearing breccia may be tentatively dated to between 224 ± 14 ka and 160 ± 10 ka, although an older age ca…
Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework
The pronounced ribcage depth in native South Americans could represent a population-specific trait maintained through long-term interactions, potentially advantageous in high-altitude settings but neutral in the lowlands. In addition, we propose that South American highlanders have a larger ribcage relative to their smaller body size compared to lowlanders. Finally, the larger and stockier male ribcage morphology in South Americans supports the n…
Sex assessment in a hominin upper second molar (RV’23-350) from the Ruidera (Spain) Middle Pleistocene paleoanthropological site: A Proteome-Based Analysis of the Amelogenin
Sex determination in fossil hominin remains is often challenging due to the fragmentary nature of the record and the limitations of morphological assessments. In this study, we apply a proteomic approach to assess the sex of an upper second molar (RV’23-350) from the Middle Pleistocene site of Ruidera (Spain). By analyzing the presence of amelogenin, a key enamel protein encoded by genes on both the X and Y chromosomes, we provide molecular evide…

Middle Pleistocene hominin presence in the Southern Iberian Plateau: Lithic assemblages from the Cueva de los Toriles site (Carrizosa, Castilla-La Mancha, Spain)
The Neanderthal cervical spine revisited
Recent studies have challenged the long-held notion that Neanderthals possessed a more stable and less lordotic cervical spine than modern humans. To investigate this hypothesis further, we conducted the first three-dimensional geometric morphometric analysis focused on the Neanderthal cervical spine, examining 43 classic Homo neanderthalensis cervical vertebrae alongside 243 Homo sapiens cervical vertebrae from diverse populations, including the…
Shanidar 3 'rings the bell: Virtual ribcage reconstruction and its implications for understanding the Neanderthal bauplan
The study of the ribcage is fundamental to understanding hominin evolution. However, ribs and vertebrae are scarce in the fossil record. Although Neanderthals are one of the most represented and, therefore, one of the most studied fossil Homo species, it is controversial whether there is a standardized Neanderthal ribcage morphotype that could differ from modern humans. Hence, we used three-dimensional geometric morphometrics to reconstruct and c…
Cumplimiento de las pautas de movimiento de 24 horas en escolares: Etapa Infantil versus Etapa Primaria
Physical activity, sedentary behavior and sleep are the three main behaviors that interact during the day. The objective of the present study was, on the hand, to analyze the level of compliance with the 24 hours of movement in schoolchildren (pre-school versus primary school) and, on the other hand, to determine the differences between different times of the week. The sample consisted of 260 schoolchildren (93 from the infant stage and 167 from …
Eco‐geographic and sexual variation of the ribcage in Homo sapiens
Up to now, Allen and Bergmann's rules have been studied in modern humans by analyzing differences in limb length, height, or body mass. However, there are no publications studying the effects of latitude in the 3D configuration of the ribcage. To assess this issue, we digitally reconstructed the ribcages of a balanced sample of 109 adult individuals of global distribution. Shape and size of the ribcage was quantified using geometric morphometrics…
Estimation of the upper diaphragm in KNM-WT 15000 (Homo erectus s.l.) and Kebara 2 (Homo neanderthalensis) using a Homo sapiens model
The diaphragm of extinct Homo might have been deeper and flatter than that of H. sapiens . • Size of fossil diaphragm estimations are within the H. sapiens range of variation. • Breathing kinematics might have been different in fossil Homo
Cranial fluctuating asymmetry in Danish populations from the Neolithic to the Early Modern Age
Fluctuating asymmetry are random deviations of an otherwise symmetrical body plan and arises from instability in development. Earlier studies suggest that levels of cranial fluctuating asymmetry may be influenced by lifestyle and quality of life in a population. It may, therefore, be useful as a stress indicator. We investigated whether cranial fluctuating asymmetry has changed in archaeological Danish populations over time, and between grave sit…
How accurate are medical CT and micro-CT techniques compared to classical histology when addressing the growth of the internal rib parameters
Rib internal anatomy and its cross-sectional morphology inform about important biomechanical or even evolutionary aspects. Classic histological studies require destructive techniques that are reprehensible depending on the case (e.g., fossils). In the last years, non-destructive CT-based methods are contributing to complementing previous knowledge without damaging the bone. Even though these methods have been proved to be useful to understand adu…

A 3D morphometric approach to endocast integration in Pan troglodytes and Homo sapiens
Neuroanatomical integration studies aim to analyse the interaction of the different brain regions. The skull and brain morphology of Hominidae presents a series of integration patterns and, one of the keys to understand the evolutionary mechanisms of our genus is to identify and quantify if these integration patterns are shared or species-specific. Delving into studies about neuroanatomical integration is crucial because of the complex interactio…
Ocupación romana de la cueva de Los Toriles (Carrizosa, Ciudad Real): Primeros testimonios y trascendencia
Se dan a conocer los primeros testimonios de frecuentación romana de la cueva de Los Toriles (Carrizosa, Ciudad Real), una gruta con una larga ocupación animal y humana, cuanto menos desde el Pleistoceno y hasta nuestros días. Aunque en la primera campaña de excavación de la cueva sólo se han podido constatar algunos fragmentos de cerámica, estos son lo suficientemente relevantes como para confirmar el conocimiento y entrada a la cavidad durante …
Three‐dimensional analysis of sexual dimorphism in the soft tissue morphology of the upper airways in a human population
OBJECTIVES: Several studies have analyzed the sexual dimorphism of the skeletal cranial airways. This study aimed to quantify the three-dimensional (3D) morphology of the soft tissues of the upper airways in a human population. We addressed hypotheses about morphological features related to respiratory and energetic aspects of nasal sexual dimorphism. METHODS: We reconstructed 3D models of 41 male and female soft tissue nasal airways from compute…
Assessing thoraco‐pelvic covariation in Homo sapiens and Pan troglodytes: A 3D geometric morphometric approach
OBJECTIVES: Understanding thoraco-pelvic integration in Homo sapiens and their closest living relatives (genus Pan) is of great importance within the context of human body shape evolution. However, studies assessing thoraco-pelvic covariation across Hominoidea species are scarce, although recent research would suggest shared covariation patterns in humans and chimpanzees but also species-specific features, with sexual dimorphism and allometry inf…

New postcranial remains from the Roc de Marsal Neandertal child
This paper presents the identification and study of three new human fossil remains belonging to the Neandertal child Roc de Marsal, found in the eponymous cave site, located near Campagne-de-Bugue, Dordogne, France. These three new fragments correspond to a right clavicle shaft fragment, a shaft fragment of the right radius and the dorsal part of a shaft fragment of hand (likely proximal) phalanx. These elements further complete the state of pres…
D geometric morphometric analysis of variation in the human lumbar spine
OBJECTIVES: The shape of the human lumbar spine is considered to be a consequence of erect posture. In addition, several other factors such as sexual dimorphism and variation in genetic backgrounds also influence lumbar vertebral morphology. Here we use 3D geometric morphometrics (GM) to analyze the 3D morphology of the lumbar spine in different human populations, exploring those potential causes of variation. MATERIAL AND METHODS: We collected 3…
Three‐dimensional analysis of sexual dimorphism in ribcage kinematics of modern humans
OBJECTIVES: Sexual dimorphism is an important biological factor underlying morphological variation in the human skeleton. Previous research found sex-related differences in the static ribcage, with males having more horizontally oriented ribs and a wider lower ribcage than females. Furthermore, a recent study found sex-related differences in the kinematics of the human lungs, with cranio-caudal movements of the caudal part of the lungs accounting…

The costal remains of the El Sidrón Neanderthal site (Asturias, northern Spain) and their importance for understanding Neanderthal thorax morphology
The study of the Neanderthal thorax has attracted the attention of the scientific community for more than a century. It is agreed that Neanderthals have a more capacious thorax than modern humans, but whether this was caused by a medio-lateral or an antero-posterior expansion of the thorax is still debated, and is key to understanding breathing biomechanics and body shape in Neanderthals. The fragile nature of ribs, the metameric structure of the…
Morphological and functional implications of sexual dimorphism in the human skeletal thorax
OBJECTIVES: The human respiratory apparatus is characterized by sexual dimorphism, the cranial airways of males being larger (both absolutely and relatively) than those of females. These differences have been linked to sex-specific differences in body composition, bioenergetics, and respiratory function. However, whether morpho-functional variation in the thorax is also related to these features is less clear. We apply 3D geometric morphometrics …
Three‐dimensional analysis of sexual dimorphism in human thoracic vertebrae: Implications for the respiratory system and spine morphology
Sexual dimorphism is important for intraspecific variation and well studied in the human skeleton. In the thoracic part of the spine sexual dimorphism is expected for differences in the respiratory system related to body mass, lung capacity, and energetics, and in the reproductive system for adaptations to pregnancy (lower spine lordosis, posture). However, little is known about sexual dimorphism in this anatomical region. We use three‐dimensiona…
Over 100 years of Krapina: New insights into the Neanderthal thorax from the study of rib cross-sectional morphology
Neandertal talus bones from El Sidrón site (Asturias, Spain): A 3D geometric morphometrics analysis
OBJECTIVES: The El Sidrón tali sample is assessed in an evolutionary framework. We aim to explore the relationship between Neandertal talus morphology and body size/shape. We test the hypothesis 1: talar Neandertal traits are influenced by body size, and the hypothesis 2: shape variables independent of body size correspond to inherited primitive features. MATERIALS AND METHODS: We quantify 35 landmarks through 3D geometric morphometrics technique…
Ontogeny of 3D rib curvature and its importance for the understanding of human thorax development
OBJECTIVES: Sagittal and axial rib orientation relative to the spine are two factors that modify rib cage morphology during ontogeny. Some studies suggest that these factors do not operate in the same way at the upper (ribs 1-5) and lower thorax (ribs 6-10) during postnatal growth, but it is unknown if the ontogenetic thoracic changes are produced by morphological changes of the ribs (intrinsic rib factors) or by external factors related to costa…
The torso integration hypothesis revisited in Homo sapiens: Contributions to the understanding of hominin body shape evolution
Objectives: Lower thoracic widths and curvatures track upper pelvic widths and iliac blades curvatures in hominins and other primates (torso integration hypothesis). However, recent studies suggest that sexual dimorphism could challenge this assumption in Homo sapiens . We test the torso integration hypothesis in two modern human populations, both considering and excluding the effect of sexual dimorphism. We further assess covariation patterns be…

Eco‐geographic adaptations in the human ribcage throughout a 3D geometric morphometric approach
OBJECTIVES: According to eco-geographic rules, humans from high latitude areas present larger and wider trunks than their low-latitude areas counterparts. This issue has been traditionally addressed on the pelvis but information on the thorax is largely lacking. We test whether ribcages are larger in individuals inhabiting high latitudes than in those from low latitudes and explored the correlation of rib size with latitude. We also test whether …
External and internal ontogenetic changes in the first rib
OBJECTIVES: First ribs bear information about thorax morphology and are usually well preserved, compared to other ribs, in bone/fossil samples. Several studies have addressed ontogeny of the first rib by studying changes in bone microanatomy and rib morphology separately, but no studies have combined both approaches to study how internal and external changes covary during ontogeny. The aim of this project is to fill this gap in our knowledge. MAT…
