...nant scientific view has linked hand preference in humans with the area of the brain that controls language. After observing hand preference in chimpanzees, which have no comparable language capabilities, we concluded there must be another reason for handedness.

...Again, that parallels how the right hippocampus in humans is involved in spatial memory. In a second study, Hopkins and Cantalupo report the first-ever evidence of an association between hand preference and asymmetries in three areas of the brain cortex in chimps.
