Why? I don’t understand the logic of what you’re theorising. If your right side is damaged, why does having your ipsilateral side help? How common would this have been from an evolutionary perspective? And if your right side is damaged, and it’s taken out your right brain, now you’ve got a right side that doesn’t work and a left side you can’t control

But, I think the visual processing explanation is more compelling - since it seems unlikely this scenario would arrive in enough non-catastrophic situations to be evolutionary significant.
