Reply To: If a pig was genetically modified to chew its cud, would it be kosher?

Yes, such a pig would be a different species from the treife pig, and it would be kosher. (Every twenty years or so, somebody “discovers” the babirusa pig, which has an stomach similar to that of ruminants, and jumps to the conclusion that it is actually a ruminant pig, and therefore kosher. This causes a huge burst of discussion until someone bursts the bubble by pointing out that it doesn’t actually ruminate, and is therefore treif after all. Twenty years later someone else makes the same discovery and the cycle repeats.)
