we are unique, but we are not magic. our traits are still derived from previous humans who evolved them because they were beneficial. and what do you know, there are studies showing disease caused from circumcision, not its lack. such as penile cancer - the risk of which is increased when one is circumcised in adulthood. the foreskin is a biologically useful mammalian trait that humans share (like eyelids, for instance) because we are not *that* unique. chopping it off does not make biological sense. of course, if you're doing it for religion than that is what it is but don't pretend it's not removing something that we adapted because it was and is biologically useful. which our ancestors lived longer and/or reproduced more successfully with than without, causing it to be passed on into future generations.
