Shmarya Rosenberg believes Hitchens' theory:
In God is not Great, Hitchens notes uneasy similarities between humans and pigs: Porcine DNA and human DNA are very similar, so much so that porcine heart valves can be transplanted into humans; pigs are noticeably smarter than other farm animals; and pig skin looks almost human, so much so that the smell and look of suckling pig and roasting human infants is, according to those who have had the misfortune of smelling and seeing both, disconcertingly similar. And make no mistake about it—many ancient Israelites had that misfortune. Hitchens thought this was the basis for the Jewish taboo against eating pork.
