“…In conclusion, the findings of this study suggest that chimpanzee hand preferences are heritable, a result that is consistent with human findings (Porac & Coren, 1981); with one previous report in captive chimpanzees (W. D. ; and, to some extent, with findings in monkeys (Brinkman, 1984; but see Brooker et al, 1981;Kubota, 1990;Westergaard & Suomi, 1997). In contrast with previous studies, this is the first heritability study in nonhuman primates in which rearing history was manipulated and allowed for a dissociation of genetic and environmental contributions to the expression of hand preference.…”

Heritability of hand preference was tested in a sample of 188 chimpanzees (Pan troglodytes). Hand preference was measured by coordinated bimanual actions, and concordance percentages were compared between parents and offspring and siblings. Among siblings, concordance percentages were compared for dyads in which both individuals were raised by chimpanzees, both were raised by humans, or 1 was raised in each environment. The results indicated population-level right hand preferences for coordinated bimanual actions. There were no significant associations in hand preference between parents and offspring. In full and maternal half siblings, concordance in hand preference was significantly greater than chance in mother-and human-reared individuals but not in cross-fostered dyads. The cumulative results suggest that the direction of hand preference is heritable in chimpanzees but the mechanism of transmission is not genetic. Several environmental explanations are proposed to explain the findings, including the potential role of maternal cradling bias and in utero fetal position.Approximately 75% to 90% of modern humans report themselves as being right-handed (Annett, 1985;Porac & Coren, 1981). The general view is that human right-handedness evolved within the past 2 to 5 million years, as evidenced by the archeological data suggesting righthand use in tool use and other activities in early hominids (Bradshaw & Rogers, 1993;Corballis, 1991). The pervasiveness of human right-handedness has led to numerous debates about the mechanisms involved in the expression of hand preference (B. Hopkins & Ronnqvist, 1998). Both genetic models (Annett, 1985;Corballis, 1997;Laland, Kumm, Van Horn, & Feldman, 1995;McManus, 1985;Yeo & Gangestad, 1993) and environmental models (Collins, 1985;Provins, 1997) have been proposed to explain the origin of human hand preference. The principal data in support of a genetic basis for hand preference are that it runs in families (Curt, De Agostini, Maccario, & Dellatolas, 1995;Laland et al., 1995;McGee & Cozad, 1980;McManus & Bryden, 1992) and that offspring typically exhibit patterns of hand preference more similar to their biological parents compared with offspring who have been adopted or raised by stepparents (Carter-Saltzman, 1980;Hicks & Kinsbourne, 1976).In contrast with humans, the historical view has been that nonhuman animals, particularly nonhuman primates, do not exhibit population-level handedness (see Ettlinger, 1988;Warren, 1980). In recent years, behavioral research in a variety of nonhuman primate species has revealed that population-level handedness can be found in some species for certain measures (Bradshaw & Rogers, 1993;Fagot & Vauclair, 1991;W. D. Hopkins, 1996b Studdert-Kennedy, & Lindblom, 1987;Ward & Hopkins, 1993). Notwithstanding, considerable disagreement remains about the interpretation of the findings in nonhuman primates as they pertain to human handedness. For instance, McGrew and Marchant (1997) argued that the evidence for population-level handedness in no...

“…These conflicting findings in primates suggest that maternal influences on offspring hand preference vary between primate species (Westergaard et al, 2001b). Furthermore, we did not find an influence of fathers, which is in agreement with findings in chimpanzees and macaques (Westergaard et al, 2001b;Hopkins et al, 2006), but not with the negative father-offspring correlation in capuchins (Westergaard and Suomi, 1997). Between siblings no significant correlations of HI were found.…”

“…In our study we found a negative mother-offspring correlation of hand preference for gray mouse lemurs, which coincides with findings in pigtail macaques (Westergaard et al, 2001b), but is not in agreement with the positive mother-offspring correlations in chimpanzees, capuchins, and rhesus monkeys (Westergaard and Suomi, 1997;Hopkins et al, 2001;Westergaard et al, 2001b;Lonsdorf and Hopkins, 2005;Hopkins et al, Fig. 5.…”

“…Although it is widely acknowledged that genetic factors contribute to handedness in humans, the precise nature of these factors remains to be clarified (Laland et al, 1995). In nonhuman primates, indications of inheritance have been found in chimpanzees (e.g., Hopkins and Bard, 1993;Hopkins, 1999;Hopkins et al, 2001;Lonsdorf and Hopkins, 2005;Hopkins et al, 2006), capuchins (Westergaard and Suomi, 1997) and macaques (Westergaard et al, 2001b). However, it has been suggested that environmental factors, such as prenatal position, hormones, and mother-infant interactions such as cradling, rather than genes, may account for the transfer of hand preference directions from parents to offspring (Westergaard and Suomi, 1997;Hopkins, 1999;Westergaard et al, 2001b;Hopkins et al, 2006).…”

In humans, 90% of the population is right handed. Although population hand preference has been found in some primate species, the evolution of manual lateralization in primates is not yet clear. To gain insight into manual lateralization of ancestral primates, we studied hand usage in unspecialized quadrupedal, nocturnal lemurs, using a large sample size. We compared two closely related mouse lemur species to explore the variation of hand preference within the same genus. We tested 44 gray mouse lemurs and 19 Goodman's mouse lemurs in a forced food grasping task. The tests were videotaped. Measures of hand preference (i.e. the hand that is spontaneously chosen for a specific task) and successful hand usage (i.e. the hand that is successful in completing a specific task) were taken to explore manual lateralization. Both species showed manual lateralization at an individual, but not at a population level. Goodman's mouse lemurs showed stronger individual hand preferences than gray mouse lemurs. This suggests that strength in hand preference is variable within the same genus. No sex and age effects were found. The hand preference of offspring was negatively correlated to that of their mothers, but not correlated to that of their fathers. Thus, no clear genetic effect can be derived from these results. In the Goodman's mouse lemurs, hand preference increased with increasing task experience. However, successful hand usage was not affected by task experience, suggesting that successful hand usage is a more stable measurement for manual lateralization than hand preference.

“…In nonhuman primates, there is some evidence that hand preferences run in families (Hopkins et al, 1994;Matoba et al, 1991) but not all researchers have reported significant associations (Boesch, 1991;Brooker et al, 1981;Byrne and Byrne, 1991;Westergaard and Suomi, 1997), and in most studies the independent effect of genetic from nongenetic factors cannot be easily dissociated (Hopkins, 1999;Hopkins et al, 2001). In other words, the evidence of heritability has mostly come from family studies in which no differential rearing or cross-fostering comparisons are made in the phenotypic expression of handedness.…”

Laterality in Maternal Cradling and Infant Positional Biases: Implications for the Development and Evolution of Hand Preferences in Nonhuman Primates

Left-sided maternal cradling has been widely reported in human populations. In this paper, I review the evidence of laterality in maternal cradling and infant positional biases in non-human primates. The review revealed some evidence of population-left sided cradling in great apes but little consistency in bias was found among Old and New World monkeys. Very little data have been reported in prosimians. I further describe how asymmetries in either maternal cradling or infant positional biases may explain individual and species differences in hand preference.
