what is the benefit of having a dominant hand/leg as compared to having equally skilled limbs?
In: Biology
It takes less time training and requires less muscle. The benefit of being ambidextrous is relatively small so it’s almost always better to concentrate on making one limb stronger and more skillful.
Compare two people: one with two equally good arms and one person with a dominant arm. Usually the dominant arm will be better than the equally good arms and the advantage that gives is greater than the disadvantage of having a weaker arm.
So, presumably for this reason, people’s brains have evolved to have dominant limbs.
