Hominin dispersals: causes, conditions, and outcomes Dispersions des hominines : causes, conditions et issues

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The ‘Out of Africa’ model that has dominated palaeoanthropology for nearly three decades was originally based on five elements: a recent ancestry to human populations; an African origin for the ancestral population; limited or no gene flow among archaic hominins and no admixture between modern humans and Neanderthals; a marked difference between the ...

The effectiveness of using carbonate isotope measurements of body tissues to infer diet in human evolution: Evidence from wild western chimpanzees (Pan troglodytes verus)* [PDF]

open access: yes, 2015
Changes in diet throughout hominin evolution have been linked with important evolutionary changes. Stable carbon isotope analysis of inorganic apatite carbonate is the main isotopic method used to reconstruct fossil hominin diets; to test its ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Transhumanism Without Transindividuation in the Age Without Epochality: Stiegler, Vice, and Radical Human Enhancement

open access: yesBioethics, EarlyView.
ABSTRACT At its core, transhumanism is utopic and apocalyptic: it tells us we will be saved through an imminent radical change of our being wrought by radical human enhancement (RHE) technologies. We are rushing, its supporters claim, towards a technological utopia so long as assorted techno‐phobes do not stand in the way.

Entheseal Patterns Suggest Habitual Tool Use in Early Hominins

open access: yesPaleoAnthropology, 2022
Systematic tool use is a central component of the human niche. However, the timing and mode of its evolution remain poorly understood. A newly developed method for the analysis of muscle recruitment patterns (Validated Entheses-based Reconstruction of ...

Atlas of cortical sulcal imprints on Pan endocasts

open access: yesJournal of Anatomy, EarlyView.
This comprehensive atlas documents the frequency, position, and variability of cortical sulcal imprints across 21 extant Pan endocasts, providing the first quantitative baseline for comparative paleoneurology. This atlas serves as a reference for distinguishing ancestral from derived features in hominin brain evolution.

The Endocast of MH1, Australopithecus sediba

open access: yes, 2011
The virtual endocast of MH1 (Australopithecus sediba), obtained from high-quality synchrotron scanning, reveals generally australopith-like convolutional patterns on the frontal lobes but also some foreshadowing of features of the human frontal lobes ...

Mechanical evidence that Australopithecus sediba was limited in its ability to eat hard foods

open access: yesNature Communications, 2016
Dietary adaptations of extinct early humans are often inferred from dental microwear data. Here, the authors employ mechanical analyses to show that Australopithecus sedibahad limited ability to consume hard foods.

A hominin first rib discovered at the Sterkfontein Caves, South Africa

open access: yesSouth African Journal of Science, 2016
First ribs – the first or most superior ribs in the thorax – are rare in the hominin fossil record, and when found, have the potential to provide information regarding the upper thorax shape of extinct hominins. Here, we describe a partial first rib from

Shape Ontogeny of the Distal Femur in the Hominidae with Implications for the Evolution of Bipedality. [PDF]

open access: yesPLoS ONE, 2016
Heterochrony has been invoked to explain differences in the morphology of modern humans as compared to other great apes. The distal femur is one area where heterochrony has been hypothesized to explain morphological differentiation among Plio-Pleistocene
