The bony labyrinth of StW 573 ('Little Foot') : implications for early hominin evolution and paleobiology Universiteit Gent
Hip extensor mechanics and the evolution of walking and climbing capabilities in humans, apes, and fossil hominins Universiteit Antwerpen
The evolutionary emergence of humans' remarkably economical walking gait remains a focus of research and debate, but experimentally validated approaches linking locomotor capability to postcranial anatomy are limited. In this study, we integrated 3D morphometrics of hominoid pelvic shape with experimental measurements of hip kinematics and kinetics during walking and climbing, hamstring activity, and passive range of hip extension in humans, ...
Multiple cross-species transmission events of human adenoviruses (HAdV) during hominine evolution Koninklijke Maatschappij voor Dierkunde van Antwerpen
Human adenoviruses (species HAdV-A to -G) are highly prevalent in the human population, and represent an important cause of morbidity and, to a lesser extent, mortality. Recent studies have identified close relatives of these viruses in African great apes, suggesting that some HAdV may be of zoonotic origin. We analyzed >800 fecal samples from wild African great apes and humans to further investigate the evolutionary history and zoonotic ...
Loss of air sacs improved hominin speech abilities Vrije Universiteit Brussel
n this paper, the acoustic-perceptual effects of air sacs are investigated. Using an adaptive hearing experiment, it is shown that air sacs reduce the perceptual effect of vowel-like articulations. Air sacs are a feature of the vocal tract of all great apes, except humans. Because the presence or absence of air sacs is correlated with the anatomy of the hyoid bone, a probable minimum and maximum date of the loss of air sacs can be estimated from ...
Cranial vault thickness variation and inner structural organization in the StW 578 hominin cranium from Jacovec Cavern, South Africa Universiteit Gent
Cytomegalovirus distribution and evolution in hominines Koninklijke Maatschappij voor Dierkunde van Antwerpen
Herpesviruses are thought to have evolved in very close association with their hosts. This is notably the case for cytomegaloviruses (CMVs; genus Cytomegalovirus) infecting primates, which exhibit a strong signal of co-divergence with their hosts. Some herpesviruses are however known to have crossed species barriers. Based on a limited sampling of CMV diversity in the hominine (African great ape and human) lineage, we hypothesized that ...
Locomotion, posture, and the foramen magnum in primates : reliability of indices and insights into hominin bipedalism Universiteit Gent
Evolution and the palaeolithic Universiteit Gent
Evolutionary theory, which has been designed with the sole purpose of describing and explaining phenotypic variability within and between species, is considered to be the base paradigm for the study of all living organisms. Basically, evolution as a process is nothing more than a continuous alteration through time of elements that are already there, without foresight or predetermined goal and therefore not necessarily leading to increasing ...
An inquiry into the different units and levels of language evolution. Vrije Universiteit Brussel
Evolutionary linguistics is a fast rising academic field where scholars working from within a variety of disciplines are providing relevant data to study the origin of language. Mirror neurons (Fadiga et al. 2000; Fadiga, & Craighero 2003; Gallese, Eagle & Migone 2007; Rizzolatti et al. 1996), the FOXP2 gene (Lai. et al. 2001, 2003), the brain genes ASPM and MCPH 1 (Mekel-Bobrov et al. 2005; Evans et al. 2005), pointing (Tomasello. ...
