Lets face it, we are mostly prey.  Left naked and afraid most of us would have our little bits all nibbled off.  We have no armour no claws no fangs.  Just our brute strength opposable thumbs and our mind.  Doesn't help against a hungry tiger.  We are no longer those humans who knew how to survive without tools.  We are a different generation but our ability to survive I think has become a matter of engineering one to accommodate us all and more.We are prey but we can build a hell of a defensive nest.
