Unexpectedly rapid evolution of mandibular shape in hominins
Scientific Reports, 2018 Members of the hominins – namely the so-called ‘australopiths’ and the species of the genus Homo – are known to possess short and deep mandibles and relatively small incisors and canines.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution
The Anatomical Record, EarlyView.Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

South African Journal of ScienceSince discovery and description of the species, Sahelanthropus tchadensis has been at the centre of a great discussion around its classification as a hominin – the first of our lineage – or an ape.

The mechanism of labor in nonhuman primates: A look inside
The Anatomical Record, EarlyView.Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Frontiers in Earth Science, 2023 Archaeological research in the Philippines has produced a timeline of currently over 700,000 years of human occupation. However, while an initial presence of early hominins has been securely established through several radiometric dates between 700 ka to

The Anatomical Record, EarlyView.Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Isotopic evidence for contrast diets of early hominins Homo habilis and Australopithecus boisei of Tanzania [PDF]
, 2016 Isotopic dietary studies of early hominins have hitherto been confined to specimens from South Africa. We are now able to report isotopic analyses of two species of early hominins from Tanzania : Homo habilis and Australopithecus boisei. The results show

Language evolution and computational capabilities: conceptualization of the first language units
International Journal of Anthropology and Ethnology, 2023 This work addresses from the perspective of evolutionary pressure, the delicate issue of the mechanisms and causes that are behind the emergence of the faculty of language among early Homo sapiens ancestors.

Evolutionary morphology of the haplorhine hamate
The Anatomical Record, EarlyView.Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

A Major Change in Rate of Climate Niche Envelope Evolution during Hominid History
iScience, 2020 Summary: Homo sapiens is the only species alive able to take advantage of its cognitive abilities to inhabit almost all environments on Earth. Humans are able to culturally construct, rather than biologically inherit, their occupied climatic niche to a ...
