Tibial torsion and pressures in the feet during walking: Implications for patterns of metatarsal robusticity

JS Wollmann, AS Marshall… - American Journal of …, 2023 - Wiley Online Library
Abstract Objectives The Dmanisi Homo fossils include a tibia with a low degree of torsion
and metatarsals with a pattern of robusticity differing from modern humans. It has been …

Midtarsal break variation in modern humans: functional causes, skeletal correlates, and paleontological implications

JM DeSilva, R Bonne‐Annee… - American journal of …, 2015 - Wiley Online Library
The midtarsal break was once treated as a dichotomous, non‐overlapping trait present in
the foot of non‐human primates and absent in humans. Recent work indicates that there is …

Medial metatarsal rigidity in extant non‐human catarrhine primates

BA Patel - American Journal of Biological Anthropology, 2024 - Wiley Online Library
Objectives This study quantifies hallucal metatarsal (Mt1) and second metatarsal (Mt2) polar
second moment of areas (J) in hominoids and cercopithecoids to address three questions …

Inter-ray variation in metatarsal strength properties in humans and African apes: Implications for inferring bipedal biomechanics in the Olduvai Hominid 8 foot

BA Patel, T Jashashvili, SH Bui, KJ Carlson… - Journal of Human …, 2018 - Elsevier
When measured as a ratio of mean midshaft diameter to bone length, the OH 8 fossil
hominin foot exhibits a metatarsal (Mt) robusticity pattern of 1> 5> 3> 4> 2, which differs from …

Integrative experimental and morphological study of the metacarpal and metatarsal bones of the Japanese macaque (Macaca fuscata)

Y Higurashi, R Goto, Y Nakano - Anthropological Science, 2019 - jstage.jst.go.jp
Primate hands and feet are versatile and offer an opportunity to examine how morphology
reflects compromises among different functions in daily activities. In this study, we …

Proximal metatarsal articular surface shape and the evolution of a rigid lateral foot in hominins

DJ Proctor - Journal of human evolution, 2013 - Elsevier
This study quantifies the proximal articular surface shape of metatarsal (MT) 4 and MT 5
using three-dimensional morphometrics. Humans and apes are compared to test whether …

Linear and angular measurements of the foot of modern humans: a test of Morton's foot types

SG Lautzenheiser, PA Kramer - The Anatomical Record, 2013 - Wiley Online Library
In his classic research, Morton established two functionally different configurations of the
bipedal and non‐bipedal primate foot: one optimized for stability, with a stiff longitudinal arch …

First metatarsal trabecular bone structure in extant hominoids and Swartkrans hominins

K Komza, MM Skinner - Journal of Human Evolution, 2019 - Elsevier
Abstract Changes in first metatarsal (MT1) morphology within the hominin clade are crucial
for reconstructing the evolution of a forefoot adapted for human-like gait. Studies of the …

Metatarsal torsion in monkeys, apes, humans and australopiths

MSM Drapeau, EH Harmon - Journal of human evolution, 2013 - Elsevier
This paper presents an analysis of metatarsal torsion in apes, cercopithecoids and humans,
compares australopiths with these species, and discusses their inferred foot morphology …

Metatarsal torsion in humans and footwear type

MSM Drapeau… - International Journal of …, 2019 - Wiley Online Library
Metatarsal torsion has been hypothesized to be a plastic trait that can be influenced by the
type of shoes worn in human populations. Wearing stiff‐sole shoes tend to result in narrower …
