Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Shared foraging behaviors between hyenas and hominins in the Middle Paleolithic Levant: New evidence from Geula Cave, Israel

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Vegetation context and climatic limits of the Early Pleistocene hominin dispersal in Europe [PDF]

open access: yes, 2010
The vegetation and the climatic context in which the first hominins entered and dispersed in Europe during the Early Pleistocene are reconstructed, using literature review and a new climatic simulation. Both in situ fauna and in situ pollen at the twelve

A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

Patterns of change in in the Plio-Pleistocene carnivorans of eastern Africa: Implications for hominin evolution [PDF]

open access: yes, 2007
This paper uses changes in origination and extinction rates and species richness of eastern African carnivorans through time to discuss issues related to the evolution of hominin behavior.

A morphometric analysis of hominin teeth attributed to Australopithecus, Paranthropus and Homo

open access: yesSouth African Journal of Science, 2016
Teeth are the most common element in the fossil record and play a critical role in taxonomic assessments. Variability in extant hominoid species is commonly used as a basis to gauge expected ranges of variability in fossil hominin species. In this study,

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 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

Mid-Pleistocene aridity and landscape shifts promoted Palearctic hominin dispersals [PDF]

open access: yes
Population expansions and contractions out of and into Africa since the early Pleistocene have influenced the course of human evolution. While local- and regional-scale investigations have provided insights into the drivers of Eurasian hominin dispersals,

A brief update on developments in early hominin biogeochemistry [PDF]

open access: yes, 2013
Although two decades have passed since the first biogeochemical studies of early hominin diet were published, the field has only picked up steam in the last few years.
