Studies of hand use in nonhuman primates suggest that several species exhibit hand preferences for a variety of tasks. The majority of studies, however, focus on the lateralized hand use of captive nonhuman primate populations. Although captive settings offer a more controlled environment for assessing hand preferences, studies of wild populations provide important insights into how handedness is affected by natural environmental conditions and thus potential insights into the evolution of… 
The evolution of handedness in humans and great apes: a review and current issues.
It is proposed that when referring to "handedness" it is more appropriate to use the terms "hand preference" and "hand use", to avoid confusion with each discipline's own definition of handedness.
Freestanding Bipedal Posture and Coordinated Bimanual Manipulation Significantly Influence Lateralized Hand Use in Rhesus Monkeys (Macaca mulatta) and Chimpanzees (Pan troglodytes)
The data support the hypothesis that both degrees of postural instability and complex manipulation, such as bimanual coordination, may influence the expression of behavioral asymmetries in primates and demonstrate robust lateralization occurs at the individual level.
Postural effect on manual laterality in different tasks in captive grey-cheeked mangabey (Lophocebus albigena).
It is confirmed that postural constraints are a major factor in the emergence of group handedness and lateralization during different tasks in captive grey-cheeked mangabeys during spontaneous food processing and 3 experimental tasks.
Hand preference in unimanual and bimanual tasks and postural effect on manual laterality in captive red‐capped mangabeys (Cercocebus torquatus torquatus)
Generally, individual laterality was found regardless of the task and behavior involved, but the number of monkeys with hand preferences and the strength of the preference increased with the complexity of the tasks.
Trabecular architecture in the thumb of Pan and Homo: implications for investigating hand use, loading, and hand preference in the fossil record.
It is concluded that trabecular bone is capable of detecting right/left directional asymmetry, but coupling studies of internal structure with analyses of other skeletal elements and cortical bone prior to applications in the fossil record is suggested.
Lateralización cerebral en chimpancés: una aproximación filogenética al estudio del cerebro humano
Resumen El estudio de la lateralización cerebral de los primates no humanos resulta esencial para comprender nuestra hominización cerebral y cognitiva, así como la filogenia del lenguaje humano. En


Lack of hand preference in wild Hanuman langurs (Presbytis entellus).
The results suggest that hand use is unlateralized in P. entellus and those individuals exhibiting some hand preferences can be viewed as statistical exceptions or perhaps subject to experiential differences.
Hand preferences in unimanual and bimanual feeding by wild vervet monkeys (Cercopithecus aethiops).
Lateral preference was examined in spontaneous feeding actions in 2 troops of wild vervet monkeys, which showed ambilaterality, with lateralization associated with task complexity, and preference appeared labile.
Laterality of limb function in wild chimpanzees of Gombe National Park: comprehensive study of spontaneous activities
Ethological data on 43 categories of limb movements exhibited by one community of wild chimpanzees in the Gombe National Park, Tanzania is presented, showing lack of lateralization for limb movement in this natural population contrasts with findings of apparent right-handedness in captive chimpanzees.

The findings indicate that postural regulation may influence hand use patterns in nonhuman primates at the population level and support the available primate hand use frameworks.
It's all in the hands of the beholder: New data on free-ranging rhesus monkeys
It is suggested that primate handedness patterns evolved with structural and functional adaptations to feeding, that they are precursors to aspects of human leftand right-hemisphere specialization patterns, and that they evolved in the following order.
It is hypothesised that chimpanzees in confined settings may show right side preferences due to (inadvertent) human influence; these can be tested empirically.
On the Other Hand: Current Issues in and Meta-Analysis of the Behavioral Laterality of Hand Function in Nonhuman Primates
It is concluded that nonhu- man primate hand function has not been shown to be lateralized at the species level—it is not the norm for any species, task, or setting, and so offers no easy model for the evolution of human handedness.

The results suggest that coordinated bimanual tasks elicit strong hand preferences at the individual level and elicit population level right-handedness.
