Ook-ook.
Is handedness a left-over (so to speak) specialization of how you hang from a tree branch with one hand while the other one manipulates fruits and other goodies? Makes sense to me. Certainly I perceive a difference not just in dexterity with one hand or the other, but a trade-off between dexterity and gripping strength. Or, at least, in how I choose hands for same.
Ook.
