This actually begs the question, would simians make the cut of Clean animals, of which there would be seven, or unclean, of which there would be two?

Also, just want to point out, isn't that a great way that God pre-called-out the later hypocrisy of the priests and pharisees? Their whole "You're unclean, I won't have any dealings with you," ran in start contrast to the earlier "Noah! Everyone's gonna die, quick, make sure you've got enough of the Unclean Animals to repopulate their species!!!" They may be weird and gross and smell like crap, but damn it, they belong to God too.
