Sacral Orientation in Hominin Evolution

open access: yesAdvances in Anthropology, 2013
Sagittal sacral orientation within the pelvic girdle of humans is a key component of posture and obstetrics. On the one hand, sacral orientation has direct influence on the lumbar curvature; while on the other hand, it has an impact on the dorsoventral dimension of the birth canal. In this study, we aim to explore the evolution of sacral orientation in

Super volcano eruptions and their impact on hominin evolution

open access: yes, 2015
Discussions relating to super-volcanic eruptions (Volcanic Explosivity Index 7-8+) and their impacts on hominin evolution tend to focus on eruptions that occurred within the last 100 kya and specifically relate to the impact on modern humans or ...

No gain from pain: Lack of nociceptor activation suggests no adaptation for defence in the evolution of European viper venoms

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Snake venoms show variability in composition at all taxonomic levels, both within and between species, and the selective pressures underlying this variation have long been debated.

And then there was us Et puis nous sommes apparus

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

The evolution of hominin bipedalism in two steps

open access: yesNature
Bipedalism is a human-defining trait1-3. It is made possible by the familiar, bowl-shaped pelvis, whose short, wide iliac blades curve along the sides of the body to stabilize walking and support internal organs and a large-brained, broad-shouldered baby4-6. The ilium changes compared with living primates are an evolutionary novelty7. However, how this

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

Pulsatory volcanism in the Main Ethiopian Rift and its environmental consequences

open access: yesCommunications Earth & Environment
The East African Rift is one of Earth’s largest continental landforms. It is recognized as a critical region for understanding hominin evolution yet has also undergone important transformation through ongoing tectonic and volcanic activity.

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.
