Development of the Jaws and Teeth in Mouse Lemurs
Rodent models have provided a detailed body of knowledge on craniodental development. Yet, it is unknown how well altricial mammals such as mice parallel primate and specifically human craniodental development. To address this, here we document the ontogeny of jaw‐related structures in a cross‐sectional prenatal sample of mouse lemurs ( Microcebus spp.). Mouse lemurs follow the same developmental sequence as humans and mice with respect to the ea…
Developmental milestones in captive Galago moholi
Systems of the body develop in a modular manner. For example, neural development in primates is generally rapid, whereas dental development varies much more. In the present study, we examined development of the skull, teeth, and postcrania in a highly specialized leaping primate, Galago moholi . Eighteen specimens ranging from birth to adult were studied. Bones, teeth, and the cranial cavity (i.e., endocast) were reconstructed with Amira software…
Ontogenetic Scaling of the Primate Middle Ear
The study of primate auditory morphology is a significant area of interest for comparative anatomists, given the phylogenetic relationships that link primate hearing and the morphology of these auditory structures. Extensive literature addresses the form‐to‐function relationship of the auditory system (outer, middle, and inner ear) in primates and, by extension, provides insight into the auditory system of extinct primates and even modern humans.…
Generation of Microclimates From the Differential Decomposition of Textiles in North Central Florida
The analysis of textiles as trace evidence is an important area of focus in the field of forensic science, because enhanced understanding of the decomposition of textiles may point to more accurate methods for estimating the post mortem interval (PMI) of remains found in association with these materials. This research is especially crucial in areas with unique climates, like the state of Florida. This study examines the generation of microclimate…
Relative tooth size at birth in primates: Life history correlates
OBJECTIVES: Dental eruption schedules have been closely linked to life history variables. Here we examine a sample of 50 perinatal primates (28 species) to determine whether life history traits correlate with relative tooth size at birth. MATERIALS AND METHODS: ) of the upper jaw were measured and residuals from cranial length were calculated with least squares regressions to obtain relative dental volumes (RDVs). RESULTS: Relative dental volumes…
Clavicular curvature and locomotion in anthropoid primates: A 3D geometric morphometric analysis
OBJECTIVES: As a component of the primate shoulder, the clavicle is expected to reflect locomotor adaptations. Whereas previous work has generally focused on clavicular length and torsion, the shape of clavicular curvature may better distinguish taxa and provide additional information about upper limb use in locomotion. This study uses three-dimensional geometric morphometrics to analyze shape differences in the curvatures of the clavicle in diff…
Mapping bone cell distributions to assess ontogenetic origin of primate midfacial form
Midfacial reduction in primates has been explained as a byproduct of other growth patterns, especially the convergent orbits. This is at once an evolutionary and developmental explanation for relatively short snouts in most modern primates. Here, we use histological sections of perinatal nonhuman primates (tamarin, tarsier, loris) to investigate how orbital morphology emerges during ontogeny in selected primates compared to another euarchontan ( …
Modern human origins: Continuity, replacement, and masticatory robusticity in Australasia
Fluctuating asymmetry and stress in a medieval Nubian population
Fluctuating asymmetry is commonly used as a bioindicator of developmental stress. This study addresses asymmetry under nutritional/systemic stress in the human craniofacial skeleton and its utility as an indicator of developmental instability. Crania from the diachronic Christian cemeteries at Kulubnarti (Sudanese Nubia) were chosen as a model for nutrition/systemic stress. Previous studies indicate that individuals from the Early Christian cemet…
The promise of geometric morphometrics
Nontraditional or geometric morphometric methods have found wide application in the biological sciences, especially in anthropology, a field with a strong history of measurement of biological form. Controversy has arisen over which method is the "best" for quantifying the morphological difference between forms and for making proper statistical statements about the detected differences. This paper explains that many of these arguments are superflu…
