Most investigators believe that nonhuman primates do not have population-level
asymmetries of hand preference. This conclusion, if correct, would imply de novo evolution …

The strong predominance of right-handedness appears to be a uniquely human
characteristic, whereas the left-cerebral dominance for vocalization occurs in many species …

The neurobiology of hand preferences in nonhuman primates is poorly understood. In this
study, the authors report the first evidence of an association between hand preference and …

Humans exhibit a population-wide tendency toward right-handedness, and structural
asymmetries of the primary motor cortex are associated with hand preference. Reported are …

Population-level right-handedness has historically been considered a hallmark of human
evolution. Even though recent studies in chimpanzees (Pan troglodytes) have demonstrated …

the claim of consistent hemispheric specialisations across classes of chordates is
undermined by the absence of population-based directional asymmetry of paw/hand use in …

This study examined hand preference in baboons in a sample of 94 subjects for a
unimanual task and in a sample of 104 subjects for a bimanual task. For the unimanual task …

In this paper, we consider human handedness and cerebral lateralization in a general
biological context, and attempt to arrive at some conclusions common to the growth of …

Magnetic resonance images of the brain were obtained from 2 gorillas (Gorilla gorilla
gorilla), 4 orangutans (Pongo pygmaeus), 14 chimpanzees (Pan troglodytes), and 4 …

This paper focuses on the inheritance of human handedness and cerebral lateralization
within the more general context of structural biological asymmetries. The morphogenesis of …
