Does the article have any theories as to why people may be missing this part of the brain? I'm curious as to whether it's considered a good or bad thing in an evolutionary sense. Are there survival traits that are enhanced or hampered by having the two hemipspheres connected?

A thread most controversial, that’s what I want to start
Full of impassioned arguments, of posting from the heart
And for this stimulation all will be thankful to me
On come on everybody it won’t work if you agree
