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

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

Journal 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 Swanscombe fossil at 90: revisiting its phylogeny, taxonomy, and place in human origins Le fossile de Swanscombe, 90 ans après : retour sur sa place phylogénique, taxonomique et dans les origines de l'humanité

Journal of the Royal Anthropological Institute, EarlyView.
The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

The emergence and complexification of symbolic practices in the Homo lineage: an archaeological and cognitive perspective Émergence et complexification des pratiques symboliques dans la lignée Homo : une approche archéologique et cognitive

Journal of the Royal Anthropological Institute, EarlyView.
Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.
