Form, function and evolution of the human hand
The modern human hand is an intriguing mix of primitive morphology and derived function.
Traditionally, its form and function are explained as a functional “trade‐off” between the …

StW 573 Australopithecus prometheus: its significance for an australopith bauplan
Abstract The StW 573 skeleton of Australopithecus prometheus from Sterkfontein Member 2
is some 93% complete and thus by far the most complete member of that genus yet found …

The position of Australopithecus sediba within fossil hominin hand use diversity
The human lineage is marked by a transition in hand use, from locomotion towards
increasingly dexterous manipulation, concomitant with bipedalism. The forceful precision …

Cortical bone distribution of the proximal phalanges in great apes: Implications for reconstructing manual behaviours
Primate fingers are typically in direct contact with the environment during both locomotion
and manipulation, and aspects of external phalangeal morphology are known to reflect …

Cognitive enrichment in a social setting: assessing the use of a novel food maze in sanctuary-housed chimpanzees
M Padrell, F Amici, MP Córdoba, M Llorente - Primates, 2022 - Springer
Foraging devices are effective enrichment tools for non-human primates, as they provide
both cognitive and manipulative stimulation that may enhance these animals' welfare. We …

Morphological integration and shape covariation between the trapezium and first metacarpal among extant hominids
Objectives The shape of the trapezium and first metacarpal (Mc1) markedly influence thumb
mobility, strength, and the manual abilities of extant hominids. Previous research has …

The impact of hand proportions on tool grip abilities in humans, great apes and fossil hominins: A biomechanical analysis using musculoskeletal simulation
Differences in grip techniques used across primates are usually attributed to variation in
thumb-finger proportions and muscular anatomy of the hand. However, this cause-effect …
