Three‐dimensional digital analysis of musteloid masticatory muscle architecture

open access: yesThe Anatomical Record, EarlyView.
Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

Evolutionary morphology of the haplorhine hamate

open access: yesThe 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.

The pelvis doesn't walk by itself: Wider pelves reduce the cost of walking over unstable surfaces

open access: yesThe Anatomical Record, EarlyView.
Abstract Walking over variable and/or unstable terrain is a key aspect of daily life and was crucial to the evolution of bipedalism. The ability to find gait solutions that maintained stability over uneven terrain for the least increase in metabolic cost was likely a hallmark of locomotor effectiveness in early humans, in particular acting as an ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.
