comment Why have humans evolved conciousness?
A Death Star might be the way to go if we wanted to include ourselves in the noble quest of extermination, but imagine the horror if some tough bacterium would get a foothold on the death star itself! : ) (As for all alternatives that don't include us humans -- it will be tough to get all the bacteria in intestines, mouth, stomach etc out of there)

comment Why have humans evolved conciousness?
@Armatus - Are you sure we could easily eradicate everything else (well, all other life) on earth? Viruses might be a tough game, especially those that live in humans. And extremely small things that replicate often and mutate successfully relatively often may adapt pretty quickly to our efforts to eradicate them (not that it would be easy in the first place).

comment Why do we feel tired if we sleep excessively?
No answers, but some speculations: Perhaps "excessive sleep" simply usually happens when people are excessively tired? Or perhaps people who once in a while sleep excessively do it to "make up for lost sleep", but that it is not really possible to make up for lost sleep, and lost sleep in general might lead to lower quality of sleep. Low quality of sleep may make you want to sleep more. In normal cases where you get up early there is perhaps some sense of acuteness or danger that makes you relatively alert (at a cost, perhaps).
