A theory I heard that I like, is that if you are getting attacked from the right, and suffer damage to the right side of your head, you probably want your right arm to work more than your left for the highest chance of fighting off the attack.
If your brain is hurt to that degree on either side, you are unlikely to be able to continue to fight. Evolution doesn’t usually work to offset unusual events like this. It is more about optimizing operations on a daily basis.
But maybe you get a few more seconds, one more swing, and take out your opponent. Your tribe kills the lion or wins the war. If the initial mutation wasn't detrimental so wasn't tested right away on an individual basis, but allowed to reproduced to form a population, it would be the group test that gets passed. Just a thought.
it should? natural selection progresses through the reproducers that survive. the ones that could attack on their right side for right side attack survived?
Survived with severe brain damage. Are they going to be able to survive for much longer to reproduce? It sounds that feature is only useful in a very specific circumstance. Evolution is usually happy with good enough. It seldom does micro optimisations like that
