comment Can someone identify this stinging plant?
Common folklore where I live is to sooth the irritation by rubbing the affected area with the leaves of Dock (Rumex obtusifolius) - which often grow near nettles. As a child I recall it being effective (though some of that was probably psychological reassurance).

comment Can extinct animals be cloned?
The premise of Jurassic Park was that mosquitoes, with a meal of dinosaur blood, had been trapped and preserved in amber. This is distinct from fossilization - an answer needs to address this.

comment Is there any biological reason for humans to rest after x days of work?
The 7-day week is a recent innovation. The Romans used an eight day week. The Incas used a ten-day week. I don't know of any evidence that prior to the last ten-thousand years people followed anything other than solar (daily and annual) and lunar (monthly) cycles.

@Alex, Sheep spend 15% of their time sleeping, the rest is either active foraging or chewing cud.
