Is it? Couldn't it be a bug in our society/economy instead? What if nature wanted us to take some naps through the day and not just one period of sleep in the night? Waking up multiple times at night wouldn't hurt too much then.

It's also a fairly recent phenomenon that we expect small children to sleep all alone in a big room without anyone else around them. Nature tells them they are small and the world (and the dark) is full of danger. Our biology doesn't give a damn if that is no longer true.
