But we've also developed distributed abilities with quite boggling amounts of specialization. If you chucked one random human on a desert island, they'd probably die. Chuck a dozen, they have a better chance of survival. Chuck a thousand, you might have a civilization. Conversely if you say chucked 2 or 100 rabbits on an island - end result is probably going to be an island full of rabbits.
