what is the benefit of having a dominant hand/leg as compared to having equally skilled limbs?
In: Biology
It takes a ton of processing power, more actual muscle, and thousands of hours of practice for your dominant side to be as skilled, dextrous, and powerful as it is.
Making both sides that good would double all of those costs, and NOT double the benefits since most things you can just choose to do with the good hand/arm/leg.
With the time and energy available, if you committed to making both sides equally good, they would end up both being less good than your current good side. Which is worse overall since now you have no hands dextrous enough for fine skills you could previously do.
