Evolution revelation
Next question - what makes an assymetric brain a better evolutionary result than a symmetric one? i.e. why do we have a right half and a left half instead of two of every segment and lobe? Is it because the benefits of a compact brain outweigh the benefits of a brain with contingency redundancies? In other words we could not have managed with a brain twice its current size (even at its current size it makes childbirth the most dangerous amongst all living creatures, especially because we also wish to walk erect). In fact why have some organs evolved with redundancies (kidneys, lungs) while others have not (heart, liver)?

Is this only true of humans or do any other creatures indeed possess redundand brains?
