My gut feel is that this is bat-shit crazy, but wouldn't it be amusing to see the response from the Jewish and Islamic world should it turn out that humans are pig hybrids? ;)
The broad (though not universal) taboo against eating primate meat has some basis in the higher risk of shared/cross-species diseases, due to a closer genetic relationship.
If there's a little pig in us, that'd argue for stronger taboos against eating pork... exactly as in Judaism and Islam.
Which is why it'd be funny.
