Whereas Charles B. Ferster’s 1957 study of a captive chimpanzee reported more right-handedness than left-handedness, William C. McGrew and colleagues’ 1999 study of wild chimpanzees did not. According to a meta-analysis of studies of nonhuman primates, captive populations are more likely to be described as right-handed than wild populations are. Statistical analysis indicates a handedness study would need a minimum of 176 individuals to show a representative result; however, the study by Ferster included a total population of 1, and the study by McGrew and colleagues included a total population of 13. This suggests that

A
the study by Ferster reliably represents handedness in captive primates but not in wild primates.
B
the study by Ferster reliably represents handedness in captive primates, but the study by McGrew and colleagues likely does not reliably represent handedness in wild primates.
C
neither the study by Ferster nor the study by McGrew and colleagues provides sufficient evidence to make a meaningful comparison about handedness in primates.
D
McGrew and colleagues likely underestimated the prevalence of right-handedness among the wild chimpanzees in the study.
