The Subadult Virtual Anthropology Database (SVAD): An Accessible Repository of Contemporary Subadult Reference Data

The Subadult Virtual Anthropology Database (SVAD) is the largest available repository of contemporary (2010–2019) subadult reference data from around the world. It is composed of data collected from individuals aged between birth and 22 years. Data were collected from skeletal remains (n = 43, Colombia) and medical images (n = 4848) generated at medical examiner’s offices in the United States (full-body Computed Tomography (CT) scans), hospitals in France, The Netherlands, Taiwan (region-specific CT scans), and South Africa (full-body Lodox Statscans), a private clinic in Angola (region-specific conventional radiographs), and a dental practice in Brazil (panoramic radiographs). Available derivatives include individual demographics (age, sex) with standardized skeletal and/or dental growth and development indicators for all individuals from all samples, and segmented long bone and innominate surfaces from the CT scan samples. Standardized protocols for data collection are provided for download and derivatives are freely accessible for researchers and students.

Digital Copies for Anthropological Research: Virtual Models and Databases

In the last two decades, a large number of anthropological papers have been focused on digital copies of pa-laeoanthropological materials rather than original skeletal remains. According to some foreign scholars, “virtual anthropology” has taken a shape of a separate field of anthropological science. One of the main advantages of “virtual anthropology” is the possibility to develop databases, datasets, digital collections and catalogues accessi-ble to the scientific community worldwide. Digitization of research objects facilitates organizational side of studies, provides access to wider data, expands the toolkit of available research methods, and also provides safety to the original materials. At the same time, the variability of types of virtual models along with the absence of generally accepted protocols complicate verification of morphometric and structures data. The main goal of this review pa-per is to structure the available information on virtual palaeoanthropological databases and the materials they contain. 3D-scanning technologies can be generally divided into surface scanning (including photogrammetry) and tomographic scanning. The first group of technologies provide 3D models of the shape of an object, accurate enough to be used in morphometric studies if resolution of the equipment is adequate for the size of the object and aims of the study. The second group is designed to scan the whole form of an object, which allows the ex-amination of its internal structures or tissues, small surface structures or dental material. Both methods have their strengths and weaknesses: while surface scans are cheaper and easier to obtain, CT scans provide information unavailable from the former technique. Assessment of qualitative and quantitative characteristics of digital copies depends on objectives of the study. The article provides an overview of 17 databases of virtual paleoanthro-pological models, which comprise either surface or CT scans, or both. These materials can be used in various fields of study, including human evolution, primatology, palaeoanthropology, palaeopathology, forensic science, human anatomy, as well as in teaching of these subjects. For each collection, approximate number of objects and terms of use have been specified.

Antropologia Virtual: novas metodologias para a análise morfológica e funciona

Bioanthropology examines skeletal morphology to infer diverse aspects of the funerary behaviour and palaeobiology of past populations. Conventional morphological metric (morphometrics) analysis has typically used linear measurements, ratios and angles. Yet, such quantifications do not allow visualization of the morphological differences nor prediction of the mechanical performance of bones (which may induce morphological differences between populations with diverse behaviours). Virtual Anthropology, which musters several techniques deriving from the exponential technological development of the past decades, provides new approaches to the analysis and understanding of the examined populations. Here, we summarize the techniques used in Virtual Anthropology and how this discipline may augment our understanding of the populations under study.

New genetic and morphological evidence suggests a single hoaxer created ‘Piltdown man’

In 1912, palaeontologist Arthur Smith Woodward and amateur antiquarian and solicitor Charles Dawson announced the discovery of a fossil that supposedly provided a link between apes and humans: Eoanthropus dawsoni (Dawson's dawn man). The publication generated huge interest from scientists and the general public. However, ‘Piltdown man's’ initial celebrity has long been overshadowed by its subsequent infamy as one of the most famous scientific frauds in history. Our re-evaluation of the Piltdown fossils using the latest scientific methods (DNA analyses, high-precision measurements, spectroscopy and virtual anthropology) shows that it is highly likely that a single orang-utan specimen and at least two human specimens were used to create the fake fossils. The modus operandi was found consistent throughout the assemblage (specimens are stained brown, loaded with gravel fragments and restored using filling materials), linking all specimens from the Piltdown I and Piltdown II sites to a single forger—Charles Dawson. Whether Dawson acted alone is uncertain, but his hunger for acclaim may have driven him to risk his reputation and misdirect the course of anthropology for decades. The Piltdown hoax stands as a cautionary tale to scientists not to be led by preconceived ideas, but to use scientific integrity and rigour in the face of novel discoveries.
