May not be a good place for this, but don't want to give up a chance. A question that has knocked around my head for some time is: Why do we sleep? I know a standard response is that we sleep to cure tiredness, but I wonder why it was ever considered beneficial for a living creature to essentially be prone and vulnerable about 1/3 of its life.
Other organisms developed a completely different cycle and/or different safe guards, especially when compared to humans. Is there much known as to why this was an evolutionary advantage at some point?
