what is the benefit of having a dominant hand/leg as compared to having equally skilled limbs?
In: Biology
There doesn’t have to be an advantage in order for a feature of anatomy to have arisen through evolution. It just has to be small enough of a disadvantage that it does not hamper survival/reproduction chances.
Humans have many flaws, our breathing holes and food holes are combined, and it results in around 5000 deaths per year in the US due to choking on food. It’s significant, but not enough for it to be an evolutionary disadvantage to the species.
Having a dominant an non-dominant hand is the same kind of deal. It’s just not a significant disadvantage.
