Philosophy Of The Cosmos - Why Alpacas Are Fluffy
So we are comfortable.
_Plausible, but actually the fluff on alpacas was produced by human breeding, not natural selection. (That's breeding _by_ humans, not breeding _with_ humans.) Jason_
that makes it a totally valid answer then if we didn't decide we wanted to be comfortable then they would not be fluffy _Josh_
Yup! I was being dumb. Jason
