My daughter would like to know why we have a dominant side. I’m pretty darn curious too.

Pretend that your brain starts out as a totally blank canvas that can process anything. When you’re born, the brain is randomly trying to process everything everywhere.
Over time, some parts are more successful than others so more of that type of processing just starts going there. Other parts of the brain pick up doing others things. Sort of like ants finding a path to food. It starts randomly, but the best path is reenforced over time.
This is a massive simplification and doesn’t explain why there are more right handers, but the brain is basically a reenforced training engine, so it starts random and pliable and becomes more rigid over time. (Again massive simplification, there are parts of the brain that always do specific things from birth, like breathing)
Also, compute distance matters so all of tals type A processing will end up happening in the same place because splitting across the brain is inefficient.
