Homo naledi is a previously-unknown species of extinct hominin discovered within the Dinaledi Chamber Rising Star cave system, Cradle Humankind, South Africa. This characterized by body mass and stature similar to small-bodied human populations but small endocranial volume australopiths. Cranial morphology H. unique, most early including erectus, habilis or rudolfensis. While primitive, dentition generally simple in occlusal morphology. has humanlike manipulatory adaptations hand wrist. It...
Techniques that are currently available for estimating stature and body mass from European skeletal remains all subject to various limitations. Here, we develop new prediction equations based on large samples representing much of the continent temporal periods ranging Mesolithic 20th century. Anatomical reconstruction is carried out 501 individuals, calculated estimated biiliac breadth in 1,145 individuals. These data used derive estimation formulae long bone lengths femoral head breadth....
Abstract: When determining an age estimate from adult skeletal remains, forensic anthropologists face a series of methodological choices. These decisions, such as which region to evaluate, methods apply, what statistical information use, and how combine multiple methods, ultimately impacts the final reported estimate. In this study, questionnaire was administered 145 anthropologists, documenting current trends in at death estimation procedures used throughout field. Results indicate that...
Significance Declining mobility levels following the Pleistocene had profound effects on human demography, social organization, and health, but exact timing pace of this critical change are unknown. Here we examine direct evidence for changing from limb bone structural characteristics in a large sample European skeletons spanning past 30,000 y. Our results show that first declined during Neolithic, at onset food production, decline was gradual, continuing several thousand years as...
The Rising Star cave system has produced abundant fossil hominin remains within the Dinaledi Chamber, representing a minimum of 15 individuals attributed to Homo naledi. Further exploration led discovery material, now comprising 131 specimens, second chamber, Lesedi Chamber. Chamber is far separated from system, and represents depositional context for remains. In each three collection areas diagnostic skeletal material allows clear attribution H. Both adult immature present. represent at...
Abstract Qualitative methods of describing sexual dimorphism in discrete cranial traits have been criticized for their subjectivity and statistical limitations. However, researchers yet to be able accurately capture the morphology these individual using traditional metric techniques. This article presents a method quantify morphological variation skeletal browridge chin 3D surface laser scans. Browridge regions are isolated from skull objectively defined landmarks planes. Region areas...
ABSTRACT Sex estimation from the skull is commonly performed by physical and forensic anthropologists using a five‐trait scoring system developed Walker. Despite popularity of this method, validation studies evaluating its accuracy across variety samples are lacking. Furthermore, it remains unclear what other intrinsic or extrinsic variables related to expression these traits. In study, cranial trait scores postcranial measurements were collected four diverse population groups (U.S. Whites,...
Significance The new species Homo naledi was discovered in 2013 a remote cave chamber of the Rising Star system, South Africa. This survived until between 226,000 and 335,000 y ago, placing it continental Africa at same time as early ancestors modern humans were arising. Yet, H. strikingly primitive many aspects its anatomy, including small size brain. Here, we have provided description endocast anatomy this species. Despite brain size, shared some human organization, suggesting that...
Abstract The cranial trait scoring method presented in Buikstra and Ubelaker (Standards for data collection from human skeletal remains. Fayetteville, AR: Arkansas Archeological Survey Research Series No. 44, 1994) Walker (Am J Phys Anthropol, 136, 2008 39) is the most common nonmetric sex estimation utilized by physical forensic anthropologists. As such, reliability accuracy of vital to ensure its validity applications. In this study, inter‐ intra‐observer error rates were calculated using...
As the role of forensic anthropologists expands to medical examiner setting, their expertise is being applied beyond traditional dry skeletal material. In such scenarios radiographic techniques can be when maceration not appropriate. This study explores use analysis laryngeal structures for age-at-death determination. Isolated human (n = 104) from individuals between ages 15 and 89 were removed at autopsy radiographically examined. The cricoid individual regions thyroid cartilage scored...
When faced with commingled remains, it might be assumed that a more "masculine" pelvis is associated cranium, but this relationship has not been specifically tested. This study uses geometric morphometric analyses of pelvic and cranial landmarks to assess whether there an intra-individual between the degrees sexual expression in these two skeletal regions. Principal component discriminant function scores were used dimorphism 113 U.S. Black individuals. Correlation values partial least...
Landmarks are the hallmark of biological shape analysis as discrete anatomical points correspondence. Various systems have been developed for their classification. In most widely used system, by Bookstein in 1990s, landmarks divided into three distinct types based on locations and significance. As others argued that different landmark possess qualities, e.g., Type 3 contain deficient information about variation less reliably measured, researchers began using justification selecting or...
Abstract Decedent positive identification via visual comparisons of frontal sinus radiographs is commonly used in the medicolegal field; however, only a handful studies have empirically tested this method. This study aimed to test accuracy assessment identifications across large and experientially diverse participant sample. A Qualtrics survey presented participants with 25 pairs cropped radiographs, asking them determine if they matched their confidence level. Radiographs were from American...
Forensic anthropology must embrace standards and credentialing that align with other medicolegal disciplines, such as forensic pathology odontology. This involves establishing itself more firmly an essential specialty in the system limiting practice to qualified professionals. Without educational or professional requirements anthropology, competencies of those involved cases vary, despite potentially serious legal impact errors. Negligent work can impede decedent identification wrongly...
