Assuming all non-humans lifeforms knew that they were meant to attack humans, the "animals" would win. There are plenty of diseases that could easily carry themselves to us in more effective ways if only they had actual brains and such, and even larger beasts are in general more hardy than we are. Humans have only got as far as we have through superior brain power and use of tools











Yeah if this was to go down it would be interesting. Also I don't think I'd class micro-organisms as animals 







I'd say the rest of animal kingdom, although we have guns, give a tiger a forest and you won't see it till it's on top of you ripping your head off.
