Why aren’t we ambidextrous, do other animals have a dominant hand/paw?
In: 6
As pointed out by other posters, ambidexterity is not common.
Most great apes, Chimps, bonobos, gorillas etc seem to have a preferred hand and it is generally the right one. This seems to even reach the sea mammals as they have fins/flippers that generally are right leaning.
“Just as most people are right-handed – a trait, remember, controlled by the left side of the brain – so do most people do the bulk of their linguistic processing in their brain’s left hemisphere. … Right-handedness, then, may simply be an accidental by-product of the way most of our brains”
