“…longer and more robust extremities) may be involved in compensatory mechanisms allowing them to grasp strongly despite neuromuscular immaturity (Carrier, ; Young, ; Lawler, ; Russo & Young, ; Young & Heard‐Booth, ). Indeed, in this study we highlighted direct relationships between tibia length and foot grasping performance, which confirmed our prediction C. Furthermore, recent studies established a link between relatively large extremities and increased grasping ability in young primates (Young & Heard‐Booth, ; Druelle et al ., ). Moreover, changes in the proportions of the limb segments were associated to a decrease in suspensory behaviors throughout the development in Olive Baboons (Druelle et al ., ).…”

“…Indeed, they had relatively longer metatarsus and tibia lengths relative to body mass. These results agree with previous studies on limb segment size and bone robusticity in another small strepsirhine, the Javan slow lorises ( Nycticebus javanicus ; Poindexter & Nekaris, ), but also with results for several haplorhines including young baboons ( Papio anubis) , capuchin monkeys ( Sapajus apella , Cebus albifrons ), chimpanzees ( Pan troglodytes) and rhesus monkeys ( Macaca mulatta ) (Young & Heard‐Booth, ; Druelle et al ., ; Patel et al ., ). In marsupials (Shapiro et al ., ), morphology was not influenced by relative age but extremities were longer in an arboreal ( Petaurus breviceps ) species than in a terrestrial ( Monodelphis domestica) one.…”

“…For example younger chimpanzees (Pan troglodytes), gorillas (Gorilla beringei beringei) and baboons (Papio anubis) display a wider locomotor repertoire, engage much more in vertical climbing, forelimb suspension and other arboreal behaviors than adults, which remain largely quadrupedal and spend more time on the ground (Doran, 1992(Doran, , 1997Sarringhaus, MacLatchy & Mitani, 2014;Druelle, Young & Berillon, 2017). Studies in baboons (Papio anubis), capuchin monkeys (Sapajus apella, Cebus albifrons), chimpanzees and rhesus monkeys (Macaca mulatta) have shown changes in the morphology of the hands and feet involving differences in bone proportions, size and robusticity (Young & Heard-Booth, 2016;Druelle et al, 2017;Patel et al, 2018). The next step is thus to investigate whether these structural changes are associated with behavioral transitions by exploring the relations between grasping behavior and morphology (Druelle et al, 2017).…”

Ontogeny of food grasping in mouse lemurs: behavior, morphology and performance

In primates, grasping constitutes a vital function involved in many behaviors. Anatomical specializations of the prehensile extremities originated early‐on in their evolution. However, the precise functional and ecological contexts that have driven this evolution remain unclear. Interspecific comparative studies show that a given morphology can induce different grasping behaviors and also that a given behavior can be performed using different morphological structures. In this context, an intraspecific ontogenetic approach offers the opportunity to describe the relations between patterns in grasping behavior and patterns of grasping morphology. We quantified manual grasping strategies and the associated morphometric (i.e. segments lengths) and performance (i.e. pull strength) traits for both limbs during the development of a small arboreal primate, the gray mouse lemur (Microcebus murinus). Our results show an early onset of grasping in young mouse lemurs. Moreover, younger individuals had relative longer hindlimbs (i.e. tibia and metatarsus) allowing them to have near‐maximal levels of grasping strength. This very fast development despite an incomplete neuromuscular development highlights the importance of this grasping function directly after birth.

The importance of locomotion to evolutionary fitness has led to extensive study of primate locomotor behavior, morphology and ecology. Most previous research has focused on adult primates, but in the last few decades, increased attention to locomotor development has provided new insights toward our broader understanding of primate adaptation and evolution. Here, we review the contributions of this body of work from three basic perspectives. First, we assess possible determinants on the timing of locomotor independence, an important life history event. Significant influences on timing of locomotor independence include adult female body mass, age at weaning, and especially relative brain size, a significant predictor of other primate life history variables. Additionally, we found significant phylogenetic differences in the timing of locomotor independence, even accounting for these influences. Second, we discuss how structural aspects of primate growth may enhance the locomotor performance and safety of young primates, despite their inherent neuromotor and musculoskeletal limitations. For example, compared to adults, growing primates have greater muscle mechanical advantage, greater bone robusticity, and larger extremities with relatively long digits. Third, focusing on primate quadrupedalism, we provide examples that illustrate how ontogenetic transitions in morphology and locomotion can serve as a model system for testing broader principles underlying primate locomotor biomechanics. This approach has led to a better understanding of the key features that contribute to primates' stride characteristics, gait patterns, limb force distribution, and limb postures. We have learned a great deal from the study of locomotor ontogeny, but there is much left to explore. We conclude by offering guidelines for future research, both in the laboratory and the field. K E Y W O R D Sallometry, gait mechanics, life history, locomotor independence, ontogeny | I N TR ODU C TI ONPrimates display an impressively broad range of locomotor behaviors, including several highly charismatic and unique behaviors not seen in other mammals, such as strepsirrhine vertical clinging and leaping, hylobatid brachiation, and hominin striding bipedalism (Fleagle, 2013;Hunt et al., 1996;Schmitt, 2010). Even primate quadrupedal locomotion, a comparatively ubiquitous locomotor mode, is characterized by several unique features relative to most other mammalian quadrupeds (Kimura, 1992;Kimura, Okada, & Ishida, 1979;Larson, 1998;Schmitt, 2010;Shapiro & Young, 2016). As such, the biomechanics, ecological context, and morphological underpinnings of primate locomotor behaviors have long been of interest in anthropology and associated fields (Dagosto & & Gebo, 1998;Le Gros Clark, 1959;Muybridge, 1887;Napier, 1967;Prost, 1965;Ripley, 1967;Wood Jones, 1916).The vast majority of previous research on primate locomotion, whether in the field or the lab, has concentrated on adult animals. To some degree, this focus on adults is understandable. The morphologic...
