“…A similar pattern is observed in the bipedal chimpanzee (Sarringhaus, Stock, Marchant, & McGrew, ). However, in a quadrupedal primate that utilizes all four limbs for locomotion, this pattern between forelimbs and hindlimbs does not exist (tamarin; Reeves, Auerbach, & Sylvester, ). Breno, Bots, & Van Dongen () explain that the pattern of directional asymmetry found in rabbits ( FA Hum > FA Fem ), which is consistent with stronger selection against asymmetry in the hindlimbs due to their more prominent role in locomotion, is present in developing fetuses (i.e., prior to incurring loads associated with locomotion) and is therefore under some degree of genetic control.…”

It has been hypothesized that fluctuating asymmetry (FA) may provide an indication of the functional importance of structures within an organism, with structures that more strongly impact fitness being more symmetric. Based on this idea, we predicted that for tetrapods in which the forelimbs and hindlimbs play an unequal role in locomotion, the less functionally important limb set should display higher levels of FA. We conducted a multispecies test of this hypothesis in anurans (frogs and toads), whose saltatory locomotor mode is powered by the hindlimbs. We also tested whether FA in the forelimbs, which play a more important role during landing, differed between families that differ in the degree of forelimb use in locomotion (Bufonidae vs. Ranidae). We calculated FA from the lengths of humeri and femora measured from disarticulated skeletal specimens of four anuran taxa (Bufonidae: Anaxyrus americanus, Rhinella marina; Ranidae: Lithobates catesbeianus, Lithobates clamitans). Our findings were consistent with the hypothesis that natural selection for increased locomotor performance may influence patterns of FA seen in vertebrate limbs, with all species displaying lower mean FA in the hindlimbs. More subtle functional roles between the forelimbs of bufonids and ranids, however, did not elicit different levels of FA.

“…It should be noted that our study evaluated Gorilla while Morimoto et al () measured Pan —leaving the possibility of genus‐level differences. Lewton () found only a few differences in the articular morphologies of captive and wild chimpanzees; however, articulations appear to be more genetically canalized during growth than cross‐sectional diaphyseal dimensions (Auerbach & Ruff, ; Lieberman, Devlin, & Pearson, ; Reeves, Auerbach, & Sylvester, ; Trinkaus, Churchill, & Ruff, ). Other studies have shown developmental changes in limb bone diaphyseal proportions among wild chimpanzees related to changes in locomotor behavior (Sarringhaus et al, ).…”

“…In spite of the wide interest in 3D trabecular bone structure and its relationship to dietary, locomotor, and other behaviors in humans and other primates (Ryan and Ketcham, ; Fajardo et al, ; Griffin et al, ; Ryan and Walker, ; Ryan et al, ; Lazenby et al, ; Ryan and Shaw, ; Shaw and Ryan, ; Ryan and Shaw, ; Tsegai et al, ; Schilling et al, ; Skinner et al, ; Reeves et al, ; Stephens et al, ), and studies of ontogenetic changes in trabecular bone (Ryan and Krovitz, ; Gosman and Ketcham, ; Raichlen et al, ), there has been very little study of bilateral asymmetry of trabecular bone in the human skeleton. Lazenby et al () investigated directional asymmetry in the trabecular bone architecture of the adult human second metacarpal from a historic population and found significant right‐side bias in several functionally‐relevant structural variables, including higher bone volume fraction, surface density, trabecular number, connectivity, and more plate‐like trabeculae.…”

Many studies have noted that the bones of the human upper limb display bilateral asymmetry, commonly linking this asymmetry in external and internal morphology to handedness and lateralization. Few studies, however, have attempted to track asymmetry throughout ontogeny. This study assesses the ontogenetic development of cortical and trabecular bone asymmetry in the humerus. We predict that directional asymmetry in structural properties will emerge in concert with hand preference and increased activity levels during the juvenile period. Paired humeri from 57 individuals from the Norris Farms #36 archaeological skeletal collection ranging in age from neonate to adult were used in the current study. Cortical bone cross-sectional properties and three-dimensional trabecular bone structure were quantified from microcomputed tomography data. The results indicate significant absolute asymmetry in all measured cortical and trabecular bone variables across all ages. Trabecular bone displays significantly higher absolute asymmetry than cortical bone. Contrary to expectations, however, this study found very little evidence for significant directional asymmetry in humeral length and cortical or trabecular bone variables, except in adults. The presence of significant absolute asymmetry in all age groups, and the lack of significant directional asymmetry in almost all variables at all ages, suggests that structural differences due to higher levels of habitual loading in the dominant arm are overlain on a template of potentially significant existing asymmetry.
