Handedness: Although VP guides LB in executing actions, most parts of actions (e.g. walking) are highly repetitive, and thus, are operated by LB
(more under title Repetitive Interactions and Condition Based Repetitive Interactions). Another reason for LB executing actions is that, as fine control of actions does not use any past data or future projections (e.g. reaching a location precisely on computer keyboard), though guided by VP
(more under title Executing an Action), LB is more suitable to execute them.
As LB is in the left hemisphere in most of the human population (more under title Location and Architecture),
and as left hemisphere controls the right hand, most of the human population find it "natural" to use their right hand to execute tasks.
Although it is natural, handedness can be modified by habit formation (which may be caused by social factors). In such cases, when done for long enough, it gets hard-wired in LB
(more under title Hard-Wired Interactions). Based on the same, besides random genetic mutations, inheritance of such habit formation is also responsible for genetic basis for handedness
(more under title Inherited Strength).
