Dynamics of Human Walking

, 2004
The problem of biped locomotion at steady speeds is discussed through a Lagrangian formulation developed for velocity-dependent, body driving forces. Human walking on a level surface is analyzed in terms of the data on the resultant ground-reaction force

Hominin musical sound production: palaeoecological contexts and self domestication

Anthropological Review
In this article we seek to integrate theories of music origins and dance with hominin fossil anatomy and the paleoecological contexts of hominin evolution.

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

Biological Reviews, EarlyView.
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

From holism to compositionality: memes and the evolution of segmentation, syntax, and signification in music and language [PDF]

, 2015
Steven Mithen argues that language evolved from an antecedent he terms “Hmmmmm, [meaning it was] Holistic, manipulative, multi-modal, musical and mimetic”.

Dynamic finite-element simulations reveal early origin of complex human birth pattern

Communications Biology, 2022
Using finite element models of australopithecine pelvis reconstructions the secondary altricial nature of early hominin newborns is revealed, indicating that the need for cooperative breeding evolved secondary to bipedalism and thus prior to the ...

Variation in trabecular bone microarchitecture across rhesus macaque (Macaca mulatta) load‐bearing joints

Journal of Anatomy, EarlyView.
Aging of bone density (BV/TV) is regional: Forelimb [left] elements gain bone sporadically (orange) but hind limb elements [right] lose bone globally (blue). Abstract Globally, human population structure is quickly trending older, increasing the prevalence and systemic burden of age‐related skeletal disorders such as osteoporosis.

PRIMATES, HOMINIDS, AND HUMANS—FROM SPECIES SPECIFICITY TO HUMAN UNIQUENESS? A RESPONSE TO BARBARA J. KING, GREGORY R. PETERSON, WESLEY J. WILDMAN, AND NANCY R. HOWELL

Zygon, 2008
In this response to essays by Barbara J. King, Gregory R. Peterson, Wesley J. Wildman, and Nancy R. Howell, I present arguments to counter some of the exciting and challenging questions from my colleagues.

Frequency of arboreality is correlated with longer hand skeletons in Gorilla: Analysis of a new skeletal sample of Bwindi mountain gorillas

Journal of Anatomy, EarlyView.
Variation in arboreality across gorilla populations is associated with systematic differences in manual digital lengths. Using a new dataset of linear metrics from the Bwindi mountain gorillas, we quantify metacarpal and phalangeal lengths in eastern and western gorilla populations across all five rays. Consistent with quantified behavioral differences,

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, Volume 248, Issue 6, Page 1026-1063, June 2026.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...
