Early Hominin Movement Patterns at Laetoli, Northern Tanzania
The site of Laetoli in northern Tanzania is famous for its preservation of 3.66-million-year-old footprint trails, among which are several belonging to an upright walking hominin (Day and Wickens, 1980; Leakey and Hay, 1979; Masao et al., 2016; McNutt et

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

A defining feature of the hominin clade is bipedality, often parcelled together with terrestriality. However, there is increasing evidence of locomotor diversity, both within the hominin clade and amongst the Miocene apes that came before them.

Delegation to automaticity: the driving force for cognitive evolution?
The ability to delegate control over repetitive tasks from higher to lower neural centres may be a fundamental innovation in human cognition. Plausibly, the massive neurocomputational challenges associated with the mastery of balance during the evolution

This study proposes an automated method to infer brown bear hair snare interactions by detecting bipedal behavior in camera‐trap images using a pose estimation model and a multilayer perceptron (MLP). A YOLO‐based model, fine‐tuned from humans and dogs to a custom dataset, achieved high performance (≈93% keypoint precision and ≈96% classification ...

The evolution of the medial longitudinal arch (MLA) is one of the most impactful adaptations in the hominin foot that emerged with bipedalism. When and how it evolved in the human lineage is still unresolved.

Growing together: Developmental integration and modularity in the human talus–calcaneus complex
This study investigates morphological integration and trabecular bone development in the human talus–calcaneus complex during postnatal ontogeny. The two bones exhibit strong integration throughout development, with differing bone volume fraction trajectories presumably reflecting their distinct functional roles during bipedal gait acquisition ...

A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Traditionally, feet have had a bad reputation. This is reflected in certain popular expressions, but also in the hierarchy that has been established between the upper parts of the body (brain, mouth and larynx) and the lower part.

Through Time and Across Traits: Evaluating Explanations of Human Evolution
ABSTRACT We argue that current explanatory practice misses two situations that can arise in any lineage, not only ours. The first is dynamic: traits continue changing in one direction when a lineage's own niche construction keeps enlarging the problem it faces.
